History of creation

Initially, the system was called "Unigraphics" and was developed by the American company United Computing. In 1976, McDonnell Douglas (today Boeing) acquired United Computing to form the McDonnell Douglas Automation Unigraphics Group. EDS acquired the business in 1991. Following the acquisition of EDS by Structural Dynamics Research Corporation in 2001, the Unigraphics product was merged with SDRC's I-DEAS CAD software. The gradual addition of I-DEAS functionality to the Unigraphics core code became the foundation of the existing NX product line.

Additional Imageware functionality has been integrated into the NX system in order to develop scanning data processing functionality (point clouds and STL data) to support reverse engineering processes.

NX Solutions

Design (CAD)

The set of applications included in the NX CAD package allows you to solve the problems of developing a complete electronic layout of the entire product and its components for subsequent use in the processes of technological preparation of production.

The functionality of the applications allows you to automate the stages of product design and release of design documentation in various forms of presentation. Both "bottom-up" and "top-down" design technologies are supported with the ability to build end-to-end development processes from product requirements to the stage of issuing data for production.

Industrial Design

Engineering Analysis (CAE)

The set of engineering analysis tools in the NX system is an application of pre- and post-processing (Pre / Post) and interface-connected computational solvers. Both the NX Nastran package and software packages from other developers can act as solvers. The engineering analysis environment can work both independently and in integration with the Teamcenter PLM system. In the latter case, all calculated data is stored in the PLM system and managed in terms of access rights, revisions, release and approval processes, etc.

The pre/post-processing application is built on the common NX CAD application platform and takes full advantage of the Parasolid geometric core. The calculated models are linked to the original 3D models, and if it is necessary to make any changes or simplifications, the user has the opportunity to edit the associated geometry without affecting the original model, but keeping track of all changes.

The functionality of the tools included in the NX engineering analysis package allows you to analyze the static loading of a structure, search for natural frequencies (dynamics), aerodynamic and thermal analysis, and also solve a number of applied specialized tasks.

Tooling design

In addition to applications responsible for the design of the product itself, the NX CAD system offers a number of solutions responsible for the design of manufacturing facilities:

• Mold Wizard is a package for designing mold elements for molded products.
• Progressive Die Wizard is a progressive die design package.
• Die Engineering and Die Design - Die design and die structure modules.
• One Step Formability - A one-step formability analysis for evaluating the feasibility of cold forming a sheet metal part.
• Electrode Design - tool design module for electroerosive machining.

Applications are created taking into account the principle of the master model and provide an associative link both with the product (CAD) and with the tooling project in CAM.

CNC programming (CAM)

Supports various types of processing: turning, milling on 3-5-axis CNC machines, turn-mill, wire EDM. The NX CAM system supports advanced types of machining and equipment: high-speed milling, feature-based machining, turn-mill multifunctional machines. Contains a built-in machine tool simulation module running in G-codes, which is used for NC analysis and provides collision control.

Association link between the original model and the generated toolpath provides automatic data updates when changes are made.

Coordinate measuring machine programming and measurement data analysis

The module for programming coordinate measuring machines (CMM) provides the preparation of control programs for CMM and analysis of measurement data, including comparison of measurement data with a 3D model. A measurement program can be created using PMI objects - information about dimensional tolerances and deviations of shapes and surfaces. In this case, the amount of manual data entry is reduced, and the control program can be associated with the original model and, accordingly, track changes. Simulation of the CMM measurement process based on the NC code (usually DMIS) is supported.

System functionality extension tools

The NX system provides a set of mechanisms that allow you to extend the standard functionality and develop your own automation tools based on the NX platform. For development, major programming languages ​​such as .NET, C++, Python, Java can be used. The system also provides an opportunity to use the internal KBE (knowledge based engineering) programming language.

Synchronous technology

The synchronous simulation technology developed by Siemens was first implemented in the NX 6 release, which was released on June 30, 2008. This technology allows you to work with a topological description of the model geometry without taking into account parametric dependencies or their absence. Traditional parametric modeling tools have a number of well-known limitations when working with non-parameterized geometry or in the presence of complex parametric dependencies. Synchronous technology makes it possible to work with such models and edit them, automatically recognizing geometric elements and relationships between them.

Application

NX is widely used in mechanical engineering, especially in industries that produce products with high density layout and a large number of parts (power engineering, gas turbine engines, transport engineering, etc.) and / or manufacturing products with complex shapes (aviation, automotive, etc.). In particular, the system is used by such large companies as Daimler, Chrysler, Boeing, Bosch, NASA Jet Propulsion Laboratory (JPL), Land Rover BAR, Red Bull Racing, MMPP Salyut, OKB im. Sukhoi”, “MVZ im. Mile", PJSC "KAMAZ", "GKNPTs" im. Khrunichev, JSC Aviadvigatel, JSC Metrovagonmash, OKB Aerospace Systems, NPO Saturn, PKO Teploobmennik, LLC All-Union Research Center for Transport Technologies (VNICTT) and others. NX is widely used by companies producing consumer goods, medical equipment, electronics.

From the editor of the site: This publication was made possible thanks to the decisive support of the Moscow office of Siemens PLM Software and the kind permission of the authoritative author, editor-in-chief and co-founder of the DEVELOP3D magazine, in which the original article was published.

Despite the 30-year history of development, more and more innovations appear in the NX system from Siemens. Al Dean takes a look at what's new in NX11, talks about topology optimizations, a new rendering platform, and discusses the future of the Parasolid core.

Where to start talking about a system like NX from Siemens? Its history begins in the 1970s with Unigraphics and the merger with I-DEAS. All the latest years go by optimization of the solution aimed at improving the usability of the system.

NX 11 introduces a new variant of the already existing Ray Traced Studio renderer. Now the module is built on
LightWork Design Iray's state-of-the-art Iray renderer that produces high-quality images in accordance with the laws of optics

With NX 11, Siemens PLM Software has skillfully added innovations and improvements to a highly advanced system.

New in basic functionality

Per last years the principles of user interaction with the NX system have undergone significant processing. The result is a fresh, clear and user-friendly interface.

Although there are no such changes in the current version, a number of system architecture updates will be noticed by almost every user. Therefore, we will first talk about them.

Most significant change One that NX users have probably already heard about is the replacement of the previously used photorealistic rendering engine (also called renderer) with LightWorks' new iRay module.

Visualization tools used to be of high quality, but now they have reached a fundamentally new level. AT new version the most modern means of creating photorealistic images based on the laws of optics appeared.

The iRay module (or iRay+ variant) uses CPU computer to calculate the path of the rays. To receive images outstanding quality, it is recommended to install the NVIDIA chipset.

The iRay+ module comes with a set of ready-to-use materials in the open MDL format developed by LightWorks. In this case, the appearance of materials is specified by layers.

For example, a car body paint job consists of a metal backing, a regular paint layer, a shimmer paint layer, and a clear lacquer top layer. This approach allows you to create realistic materials, and not their inaccurate and low-quality models.

The standard delivery also includes a set of background images with high dynamic range (HDR), speeding up and facilitating the process of setting up lighting. The system has both a rich library of ready-made HDR images and tools for working with lighting, in particular -HDRLightStudio.

Interestingly, in version NX 11, Siemens also offers a cloud-based network visualizer. This is a free solution from Siemens, but requires an NVIDIA iRay server from NVIDIA.

You will be able to perform distributed rendering on multiple network computers at once. There is talk about the emergence of a cloud-based visualization service, but it is too early to discuss this issue.

One final interface note: all of the above visualization tools are built into the existing Ray Trace Studio module and therefore available to all users (with the exception of the network distributed renderer). There are no restrictions on the resolution of the generated images. For presentations, you can even render 4K images around the clock.

Points and Facets

One of the main innovations in this version is a significantly expanded support for working with point clouds and facets.

NX already had tools for working with facets and converting meshes to surfaces (the traditional "reverse engineering" approach).

The new NX Topology Optimization module implements the expected workflow. The user sets the search space for design solutions. This indicates which structural elements should be retained, which sections of the geometry are to be optimized (in the following figure they are marked with a transparent pink), and which ones should not be touched at all (marked in yellow in the same figure). Then boundary conditions are introduced: loads, constraints, material properties, etc.

Siemens licensed topology optimization tools from Frudtrum and integrated them directly into NX

Finally, the parameters of the optimization process are set, such as the target mass of the product (therefore, it is required to specify the properties of the material, and not just the required weight reduction in percent).

It is possible to indicate symmetrical elements (there is such an element in the previous figure), as well as the speed and step of the optimization process. As a result, we get exactly what a modern topology optimization module should do: a part of the best shape that ideally solves the problem set by the designer.

Interestingly, the second generation of such instruments is already appearing.

Together with the new integrated modeling tools, you get an excellent work environment for the design and technological preparation of the production of parts and assemblies made by additive methods and characterized by exceptionally low weight.

However, these same tools have great potential in the preparation of traditional production, although the creation of a model of a cast or machined part based on a mesh is a little more difficult process.

Construction of sweeps

AT latest versions NX introduced a number of tools focused on specific industries, and primarily on the aerospace industry.

In NX 10 version Special attention was given to the design of spars and ribs of the wing. This trend is continued in the NX 11. In particular, there are tools for designing connections between spars and ribs and constructing flange cutouts in ribs.

In addition, this version introduces tools for constructing unfolded surfaces of double curvature, and they do not depend on the manufacturing technology and the material used (fabric, plastic, metal).

For several years now, NX has been able to unfold one or more complex surfaces, thereby obtaining a model of the workpiece. But it was a complex process done in the CAE module, so the developers at Siemens decided to create a similar tool in the construction environment.

New development tools work in a different way - without involving the CAE approach and the finite element method. They use an algorithm that does not depend on the properties of the material for calculating the minimum deformations. It gives almost the same results, but works several times faster. It takes seconds, not hours, to prepare the calculation.

It is enough to select one or more unfolded surfaces, specify a point in space through which the unfolding will pass, select the main unfolding direction - and you're done!

Analysis tools are also provided, in particular, plotting surface curvature diagrams showing potential points pinchings and places of tears.

It is also interesting that the new approach made it possible to implement a number of additional features. In particular, you can create a sketch on a flat pattern (cutout, stiffener or an additional layer of composite material), and new elements will automatically be transferred to the original “folded” model.

There are new tools for projecting a 3D sketch onto a surface (to create a cutout), and the cutout geometry will correspond to the shape of the surface (rather than a projection onto a plane). This is very convenient, for example, when constructing windows and other openings in the fuselage.

In NX 11, commands created for designing ribs are now available when modeling sheet bodies. These include "Flange Cutout" (built on a reamer) and "Lightweight Cutout" (a flange with a stiffening flange bent to a given angle). In addition, you can build a plane, based on the base surfaces, which is used when building the external and internal geometry of molds.

It is necessary to mention certain changes in the configuration of various system options. Now all the tools for working with sheet bodies for the aerospace industry have been transferred to the advanced sheet body design module. All of them are collected in one place, and they do not have to be bought separately.

NX 11 introduces new fast unfolding tools for complex surfaces that do not use the CAE approach

Variable displacement surfaces

We rarely cover any one new feature in CAD. But, in my opinion, this feature deserves special mention. It shows how perfect modern intelligent systems have become, and how big influence users are exerting on the direction of their further development.

So, let's talk about the "Variable Displacement Surfaces" feature.

Suppose we have a set of surfaces - say, describing the outside of a car door. Now imagine the inside of the door being welded to the outside.

This inner part very different in design. It has reinforcing elements necessary to reduce weight, as well as many other elements that provide access to the inside of the door, the installation of various equipment and cladding panels.

Designing the inside of the door - difficult task. As a rule, when solving it, offsets relative to a single outer surface are used. Introduced in NX 11, the new "Variable Offset" operation allows you to create basic geometry and set offsets in specified areas as a single element.

Consider the following figure.

New Variable Displacement Surface operation creates complex and lightweight structures from a single set of surfaces

It shows how, based on a single surface, a new surface, not only separated from it by equal distance, but also containing all the necessary reinforcing elements.

You are in full control of the process by setting the offset values ​​and choosing how the blend is built for each offset, all based on a single sketch and a single feature.

Design and technological information and 3D elements in the drawings

The last new feature in NX 11 that we'll look at is not modeling or blueprinting in isolation, but a combination of the two.

Drawing-based design information (PMI) or 3D design elements have been actively discussed for several years.

In a number of industries, these elements have not been widely adopted, while in a number of others they have been successfully implemented.

One of the difficulties is that in many cases PMI elements are affixed directly to the models and then transferred to the 3D drawing. The reverse sequence of actions is used extremely rarely. This makes sense if the design is done from scratch. But if there are materials accumulated over years and decades, then the process of transferring extremely important dimensional and geometric tolerances from an old drawing to a 3D model turns out to be lengthy and very laborious.

To solve this problem in NX 11, you can create a product model associated with drawings and basic dimensional and geometric tolerances. Then complex algorithms transfer information from the drawing back to the 3D model.

The possibilities of new design tools for aerospace structures have expanded, and their distribution among the system modules has been simplified

Conclusion

It's always difficult for me to write about NX.

In the world of 3D design, the system has become legendary. It has existed in its current form for more than a decade, and its roots go back to the 1970s, during the days of I-DEAS and Unigraphics.

Such a rich past is evident both in the breadth of the system's capabilities and in its user base. NX has designed some of the world's most complex products. It is able to solve problems that other design tools do not even approach.

Despite the high perfection already achieved, new innovations are added in each version. In this version, it is worth noting the appearance of the combined modeling technique built into the Parasolid core, which belongs to Siemens and is developed by its specialists.

Although teamwork with meshes, surface and solid models is not absolutely new concept, and some systems implemented this years (if not decades) ago, the appearance of such functionality in such a popular environment as NX clearly shows what can be achieved even in the early stages of development.

Other innovations are topology optimization tools that are of increasing interest. This is due to the growing use of metal 3D printing technologies, although topology optimization is applicable in many other areas.

Siemens NX is a program (complex of utilities and modules) that consists of CAD, CAM and CAE systems. This software is universal tool used by professional engineers and designers.

NX modules

The NX Modular System allows you to purchase only the modules you need today.

Modeling (CAD)

NX allows you to design complex products, including piping, electrical wiring, sheet metal, and plastics, helping you increase productivity, reduce development time, and reduce costs.
Studio for Design - connection industrial design and modern means engineering analysis in one integrated package allows you to quickly and accurately display various options without limiting the designer's freedom of action. This solution eliminates compatibility issues and data loss, does not require future users to be trained in many applications.

Product appearance is influenced not only by aesthetic or engineering considerations, but also by layout and manufacturing constraints. That's why industrial designer, who is ultimately responsible for the aesthetics and convenience of the product, must be able to adjust its shape at all stages of development. NX developers took this into account: the designer and the constructor work in the same system, the model is built only once, associativity allows you to reflect changes in the appearance of the product at all stages of its design.

Industrial Design

NX offers the Studio for design solution: a set of tools for solving industrial design problems. The provided opportunities are in no way inferior to the capabilities of specialized programs.

The designer is offered tools for creating and managing the appearance of surfaces, allowing to build models of very complex shapes with micron accuracy. Freeform surfaces are stretched, compressed, and sheared by moving the slider in the dialog box.>

For dynamic analysis of surface quality, a special tool is used, through which it is possible to evaluate its shape. How important this is is known to every specialist. For example, discontinuity of the second derivative on the surface of a car means a glare visible to the eye, in aero- and hydrodynamics it means a local change in the flow conditions. The results of the analysis can be obtained both in graphical and numerical form.

Visualization tools allow the designer to prepare visual presentations without making expensive layouts. Various textures and materials overlay functions are available, which provides the required realism without modeling complex surface reliefs. The designer can also create special effects and insert bitmaps. To achieve the desired result, you can change the light sources, color, shadows, background image. It is possible to dynamically build photo images on one or several views, and even on a fragment of a model view.

Design, release of technical documentation

You can create an assembly of any nesting depth, consisting of an unlimited number of components.

NX is a 3D solid hybrid modeling system that provides the engineer with everything needed to work with solid, surface and wireframe models. All functions for working with a solid body and a surface are reflected in a fully associative, parametric construction tree. The navigator visually represents the elements of the model and the order of its construction, allows you to select structural elements, quickly change them and the links between them. The history of building the model can be viewed step by step, it is allowed to copy and paste structural elements into the model. The number of elements from which the part is built is not limited. . NX allows the designer to work directly with the geometric elements of the 3D model, which allows you to make necessary changes both parameterized and non-parameterized models, as well as converting surfaces and solids into generic elements and entering them into the design database for reuse.
Full featured spreadsheets allow you to specify not only complex systems equations, but also geometric expressions. You can create and manage families of parts, perform iterative analysis against specified criteria, and build a library of standard products used in your business.

Contextual search, change management, intersection detection, powerful visualization tools, data management - all this ensures that data integrity is maintained throughout the design process. When modeling assemblies, the coordinated work of the entire development team is carried out within the framework of a single concept and uniform requirements for the product being developed.

The presence of an associative connection between parts greatly simplifies the work: when one part changes, all associated with it automatically move or even change their geometry. It is possible to simplify exact models by replacing them with conditional bodies, which is especially convenient when analyzing options, when only the approximate outlines of an object are important, indicating its location.

The assembly modeling system has its own means of controlling the intersections of parts and calculating the mass-inertia characteristics of assembly units. These tools are optimized to work in an assembly with a large number of parts. You can iteratively carry out such calculations in the course of product design. A three-dimensional model of a large assembly allows the developer to evaluate the possibility of mounting and dismounting various units of the designed product, the convenience of access to them. You no longer need to create complex full-size layouts. All this together with early detection mutual intersections parts allows not only to improve the quality of the project, but also to reduce the time of its creation, reduce costs.

The drafting environment includes a set of tools that can be used to create any drawing based on an existing 3D geometric solid model, wire model, and sketches. You can create a drawing of any complexity and according to any standards. Full associative connection of the drawing with the geometric model is supported.

Basic functionality when working with drawings:

• graphical interface with extensive use of icons;
• interactive setting of graphic attributes;
• inheritance of existing properties graphic elements drawing;
• automatic construction of orthogonal and additional views with the removal of hidden lines;
• automatic dimensioning on geometry built from sketches;
• special symbols associated with geometry (welding, surface finish, tolerances for geometric deviations);
• automatic creation of product composition specifications;
• convenient functions for setting and editing text.

It is possible to control the image by hiding or showing individual drawing objects according to specified conditions. In addition, you can specify whether one or another part intersected by the cutting plane should be cut (in some cases, for example, cuts of bolts and shafts are not shown).

Production (CAM)

The CAM (Computer Aided Manufacturing) modules of the NX system are among the best in the world. The NC program generator is based on proven machining processes. It includes processing rules designed to create programs with minimal input from an engineer.

The distribution of data between the design module and other NX modules (including CAM modules) is based on the concept of a master model. The associative relationship between the original parametric model and the generated toolpath makes updating the latter quick and easy.

The resulting tool path can be edited in graphic or text mode, and then view the changes in the processing program on the entire path or only on the selected section, changing the speed and direction of movement. There are functions that allow you to extend or cut the toolpath to certain limits (clamp, jig or notch on the part itself).

To run a program on a particular machine, it must be recoded into the machine codes of that machine. The NX system includes a special module for setting up postprocessors for any control systems and CNC machines. The post processor program uses the tcl language, which opens up ample opportunities for making any unique changes to the post processor.

All basic turning operations are combined in a special module, which provides the technologist with powerful functionality for roughing and finishing, grooving, threading and drilling on a lathe. Automatic detection processing area for roughing and finishing operations allows you to get the result faster - especially in sequential operations.

The animation of the processing process is very informative: a three-dimensional workpiece is displayed on the screen, the removal of material is displayed during the playback of the operation. The tool used for all types of turning can be easily defined using a set of parameters or taken from a tool library pre-generated at the enterprise.

For milling, the workplace of a technologist, depending on the complexity of the tasks to be solved, can be equipped with a different set of tools available in CAM modules. This approach makes it possible to obtain a solution that is optimal in terms of cost / efficiency and gives the engineer the opportunity to form such tool paths that can be implemented on the existing machine park of the enterprise.

At the stage of preliminary removal of material, it is possible to determine various ways cutting into the workpiece and machining strategies. At the same time, the cutter diameter overlap on subsequent passes, depth in height when moving to the next platform, clearance to vertical walls, and bottom line processing. The high-speed machining generator has the capabilities of a circular and helical approach to the part, creating a helical toolpath of a machining template, slowing down at corners, controlling multiple pockets at the same time, and spline interpolation of the output toolpath.
At the roughing stage, it is possible to create the necessary trajectory on elements of the most complex shape. If the geometry being processed was created in other systems and after the transfer a lot of overlaps and gaps were found between the surfaces, the system tool will allow them to be corrected or processed with the specified accuracy. Thus, the roughing process is almost completely automated.

During the finishing phase, the engineer is offered a wide range of tools to obtain toolpaths for both 3-axis and 5-axis machining, where there is complete freedom spatial orientation cutter axis. The system has intelligent functions for selecting the processing area, provides the use of a variety of processing methods and templates, including processing along the borders, radial, concentric circles, zigzag along a given path, spiral and arbitrary. In addition, there are methods for controlling cutting conditions when moving the tool up and down, as well as in a spiral. You can define and save the boundaries of raw areas.

With five-axis machining, it is possible to specify the tool axis using surface parameters, additional geometry, and geometry that defines the cutting path. Provides high quality surface finish.

Enormous time savings in the pre-machining or finishing of a part are guaranteed by a special function that analyzes the entire geometry of the part and finds double contact points. In other words, it determines the angular conjugations of surfaces. The processor automatically generates single or multiple tool passes to remove material in these areas.

In situations where the engineer needs to control every step of creating a toolpath, a feature will come to the rescue that allows you to interactively create a toolpath in parts, while maintaining full control at each step.

A special module provides electrical discharge machining of parts in the mode of two and four axes, using models in wire geometry or a solid body. When editing and updating the model, all operations retain associativity. Various types of operations are offered, such as external and internal processing with multiple passes and processing with complete combustion of the material. Trajectories are also supported, taking into account the location of the clamps on the workpiece, various types of wire and generator operating modes. As with milling operations, an invariant postprocessor is subsequently used to prepare data for a specific machine. Popular EDM machines are supported: agie, charmilles and others.

NX has developed a procedure for measuring with RENISHAW sensors in five dimensions. Measurement control points can be located anywhere on the surface that is accessible to the probe.

Machine Simulation (CSE)

Allows you to control control programs before transferring them to the shop. This will protect the equipment from any damage and breakage, as well as reduce the debugging time of the program on the machine and increase the productivity of processing. Many CAM systems perform machine tool simulations based on an internal representation of the toolpath. Such simulation does not take into account postprocessor errors and requires additional verification on the machine or a specialized software package.
NX performs machining simulation in G-codes, which guarantees the identical operation of the machine and the simulator. Tracks collisions with tooling and machine components, as well as limit movement along the axes.
At your request, we can develop a kinematic model of CNC equipment for subsequent use in the NX built-in simulation module.

Engineering Analysis (CAE)

The NX system implements the ability to create and analyze complex mechanical systems with large relative displacements. Available tools allow performing static, kinematic and dynamic analysis of mechanical systems.

Simulating the movement of a mechanism allows you to directly see the movement of its parts. This is important, but often it is not enough. NX provides the engineer with a tasking tool to analyze intersections, minimum clearances, and trace moving parts. During the subsequent simulation of the movement, different conditions can be set: stop the movement when the gap between the parts touches or decreases, create a body at the intersection of the specified links, give a message about the violation of the condition and continue the movement. Analysis of the operation of the mechanism also includes the possibility of determining and presenting in a tabular or graphical form the fields of displacements, velocities and accelerations of points of interest. The reaction forces are analyzed, which can be used to calculate the strength of these parts.

To solve the problems of modeling mechanical loads and heat transfer processes, strength analysis of the designed structure, a special tool is used, which, like all previous ones, is deeply integrated and associated with the system database.

The mechanism can be determined as based on a simple set individual models in one part (file) and at the assembly level. The latter option is more convenient: it allows you to convert the specified assembly constraints (joining conditions) into kinematic relations. Here is another one implemented basic principle NX: once entered information is used in the work of other modules in solving a variety of problems.

The creation of the mechanism includes the following steps:

• definition of mechanism links as a set of any geometric elements: solids, surfaces, curves, points;
• setting kinematic relations between links: rotation in a plane, linear movement, rotation with movement along the axis of rotation, screw pair, belt drive, universal joint, spherical joint, two-axis movement in a plane, gear rack, gear train, movement of a point along a curve and "running in" curve by curve;
• definition of springs (rotational and translational motion), damping elements and elements of mixed type;
• specification of the applied forces and torques, as well as various occasions, which are the result of the interaction of two bodies;
• setting the law of motion in the form of a standard linear function, a harmonic function, a certain function of motion of a general form.

Upon completion of these stages, a time interval is set, and motion is simulated.
In order to achieve the optimal result and the required performance of the mechanism, it is sometimes necessary to create and calculate various scenarios (or, in other words, options) for the behavior of the product. The script tree navigator will help you with this. A new script of the mechanism can be obtained on the basis of the existing one: by copying it and then making changes. Such a function does not require a redefinition of the mechanism. Fast direct access to changes in the geometry of parts defined as links makes it easy to check various options for the placement and operation of the mechanism.

To conduct research on various design options (which may differ from each other in geometric dimensions, the presence or absence of structural elements, material, loading conditions, fastening, etc.), as in the case of working with mechanical systems, scenarios are assigned. To eliminate the need to redefine some data, new script can be obtained on the basis of a previously created one, the data of which will be inherited automatically.

The NX system provides special means, which allow you to build a finite element mesh based on existing geometry. Supported elements are shells (triangles and quadrilaterals) for sheet products, tetrahedra for solids, and various linear elements, including beams, flexible links, and springs. Directly on the model, you can set the local and overall mesh density. All completed constructions are associated with the part model, and therefore, when changing the parameters, the parts change automatically. Node and element data can be displayed in a variety of ways.

When the finite element model is built, the data is transferred to the specified calculation application. NX's own tool offers a wide range of calculation methods, including linear statics, natural vibrations, buckling, support for contact elements, and stationary heat flow calculations. Isotropic, orthotropic and anisotropic material models are supported; temperature changes in the material can also be taken into account.

The results of the analysis of the stress-strain state of the product are presented in an intuitive color graphical form, which facilitates their interpretation. They can be shown as animations and data from different scenarios (load cases) can be compared in the same result window.

This approach, based on the assignment and analysis of scenarios, allows you to manipulate at the early stages of the project various options products and find the optimal design solution.
For plastic injection modeling, a special module has been created, which has a preprocessor, analysis tools and a postprocessor. By specifying a calculation model associated with the geometry of the part, it is possible to analyze the casting process in terms of pouring time, the probability of formation of air bubbles, lines of soldering flows and the probability of obtaining a complete casting. The library is used in the calculation typical materials. There are tools for visual emulation of the process on shaded or wireframe geometry. The results of the analysis include animation of the movement of the casting front, filling time, the location of the seam lines, the degree of filling, and temperature changes during the casting process.

All this allows you to evaluate the suitability of the created model and, if necessary, make changes to it.

Special applications

NX offers a wide range of tools for specialized applications. Design of sheet parts manufactured by stamping, drawing, forming weldment creation assistant, tools for designing pipelines, cables, electrical wiring and a module for creating parts from composite material.

Master processes reflect the world's design experience for common types of structures and technical processes. They are an example of the accumulation of knowledge of the world industry and are presented in the form ready-made solutions. The master processes offered by NX are characterized by:

• clear step by step instructions building and execution;
• linking a chain of complex operations into an automatically executed sequence;
• the ability to customize to your own standards and rules;
• open architecture for writing your own master processes.

MoldWizard. An automated application focused on the mold design process allows users to create models that are fully associative with the geometry of the molded part, even for parts whose geometry has been imported into NX from other CAD systems. MoldWizard allows you to reduce the time of designing molds for molding plastic parts by more than ten times.

Progressive Die Wizard. The master process for the design of progressive dies can significantly reduce the time for designing dies and reduce the number of errors made by the designer of dies during design.

Die Engineering Wizard. The process of designing die tooling for car body parts. Determination of technological transitions for obtaining a part, designing extrusion cutting and flange dies, accounting for springback compensation when cutting, when bending flanges, as well as local springback in certain areas. This allows you to get a more accurate geometry of the working surfaces of the stamp.

Die Structure Design. Design of dividing dies for body parts. The master process allows the user to create separating die features such as top cutoff blades, bottom cutoff blades, slitting blades, workpiece scrap removal surfaces, and so on.

Optimization Wizard. The optimization master process allows the designer to confidently solve complex engineering problems. Offers a quick and easy method to obtain an optimal design solution based on given variables and constraints.

Circular sections are used in hydraulic, pneumatic lines and electrical harnesses; sections of the appropriate shape are used for metal structures of heating and ventilation systems. Each application has its own library of standard elements: sets of connectors, fittings and fasteners. Special tools are used to build complex 3D alignments in an already created assembly. The results of the work include accurate calculation of cable lengths, tables of pipe bends, calculation of diameters of cable bundles, automated generation of wiring diagrams and a significantly simplified procedure for creating specifications.
Another special module of the NX system will help to execute the prototype model of the wiring layout. The initial information for laying cables is a connection table, which can be obtained from your program. Working in three-dimensional space, the designer outlines the location of the center lines of future wiring and electronic components. Next, the system checks for the presence of all necessary connections, builds solid models of bundles according to center lines, controlling the minimum bending radius, and releases the specification.

It is possible to design sheet parts that are made by stamping, drawing and forming. The main functions are a bend along a curvilinear rib, as well as a connecting surface built between two bodies. Edges and curves can be used as the geometry for constructing a connecting surface. A sheet body is built in the context of an assembly using the geometry of other parts. There are functions for unfolding complex surfaces. These functions use different algorithms specific to different processes and materials.
Reamers of various parts in any quantity can be used for optimal layout on a sheet blank. The parts to be laid out, the number of copies, and the type of blank to be used are selected. "Automatic nesting" allows you to choose between alternative strategies by controlling the placement of nested parts. The program optimizes tool change and part punching to minimize sheet movement.

The Welding application allows you to design welded joints using commonly used welding methods in the industry. Designer can design spot welding, roller weld and arc welding of various shapes (grooves, grooves, ribs, etc.). After the model is created, a drawing and accompanying documentation are automatically created. The module also supports the creation of adhesive joints.
