Increase Competitiveness Through Integrated  Mold & Tool Design

The pressure on mold and tool-makers is relentless. Time is always of the essence, and as cycle times reduce, further demands are made. Mold & tool production that took 4 months last year is now demanded in 3 months this year.  And so it goes on. Even when a part design is delivered late, the completion target for the mold or tool often remains unchanged

With these ever decreasing design-to-manufacturing cycle times and increasing complexity of the parts to be produced, toolmakers need to maximize the efficiency of the complete mold and tool design process

To do this toolmakers need to be able to:

  • Accelerate the design of molds & tools and ensure that that can produce the most complex of parts, reliably and to the required cost and quality targets.
  • Simulate, early in the design process, and compensate for the effect of deformation introduced by the manufacturing process such as material shrinkage, warping or spring-back.
  • Respond quickly to change requests – whether through late changes to the design of the part to be produced, or the need to address problems found during the manufacturing process itself. 

To addresses these challenges, the CATIA Mold & Tool design solution from Dassault Systèmes provides comprehensive and fully integrated capabilities specifically developed to meet the needs of mold and tool designers. These capabilities include the following features:

  • Rapid design of molds and tools
  • Process specific mold & tool design capabilities such as semi-automatic creation of parting surfaces, mold cores, cavities, runners, lifters and inserts.
  • Faster and safer design of complex tool assemblies through ‘smart’ components and standardized resources that embed custom behavior.
  • Advanced simulation & validation: Simulate the part forming process in order to quickly and accurately compensate for material deformation.
  • Integrated change management – Quickly identify the impact of a part change on the mold or tool, with full associativity between the part the mold and tool forming surfaces so that design changes can be propagated to the mold & tool designs.

Many leading companies have gained significant competitive advantage through these capabilities, with typical benefits being:

• Improved the whole mold & tool design process time by 70%.
• Achieved time savings of 30% across the initial mold design process.
• Reduced the time for manufacturability analysis from DAYS to hours
• Accelerated mold core & cavity design by 70 %.

In today’s digital world it is more competitive every day. To get ahead of the curve, companies are looking for a means to expand their engineering capabilities such as electromechanical, human engineering, industrial design and styling, tooling and fixture design, or factory design. Many companies have a dedicated pool of NX licenses and are simply looking to add a couple of add-on modules for a few specific jobs but hesitate to buy them due to cost. Wouldn’t it be nice to have a pool of add-on licenses from which to pick and choose for those one-off jobs?  Now you can — through Siemens’ NX Product Engineering Token Licenses, also known as Value-Based Licensing.

Whether you manage or own a small, medium, or large company…token licensing can add flexibility and value to your product design capabilities and save you money. You can have access to a broader NX product portfolio without making a large investment.

What is NX Token-Based Licensing?

Token licensing provides a flexible and cost-effective method for you to run almost any NX Product Engineering add-on module including multiple translators. The token pool does not include products with royalty or programming authoring tools (NX Open Authoring). However, with more than 50 products in the pool from which to choose, you will have the flexibility to perform the engineering and design work necessary for your needs without having to make a separate purchase. Look at the wheel graph below to see a sample of the many available modules.

Token licensing is like “per-seat” floating licenses as both require you to check out a needed license, then check it in when you are done using it — making it available for access by a different user. The two options differ in that access to products in the per-seat floating license scenario is comprised solely of the products the company has purchased whereby token licensing allows access to every product in the token license pool. You have a greater set of products that can be easily accessed when you need them. No more infrequently used software sitting on a shelf.

How does NX Token-Based Licensing Work?

For starters, tokens are added to a base application such as: Mach 1 floating and above, or an NX Automotive Bundle, or a Daimler Supplier Bundle. Each NX application in the token pool consumes a defined number of tokens when in use. The total number of applications and which specific applications can be checked out (on top of the Base Application) is limited by the number of tokens the user has available.

Here is an example of how tokens work. Let’s consider a configuration of five Mach 1 floating seats (NX11001) and a 100 token value pack.

At 9 AM the token pool is full and ready for use.

At 9:30 a User 1 starts using NX Human Modeling… the Human Modeling app uses 26 tokens leaving a remainder of 76 tokens available for use.

Now at 9:45 AM, User 2 starts using NX Realize Shape. This app uses 35 tokens leaving a balance of 39 tokens available for use.

At 10:15 AM, User 1 finishes with Human Modeling and the tokens are returned to the pool leaving a balance of 65 tokens available, and ready for use.

Finally, at 10:30 AM, User 4 starts Routing Base, and… well you get the picture…!!!

We can help you size the pool and get the best configuration to suit your needs. You will need to consider the number of users accessing the pool and the “daily use” NX products versus “occasional use” NX products. Tokens are best used for “occasional use” products, so if you have a product that you rely on daily, it may be better as a floating add-on. Token pools are most cost-effective when there is a wide variety of NX applications needed.  In general, if four or more add-ons are needed then token-based licensing is an attractive option. You can mix tokens and floating add-on licenses to give you the most flexibility at a good price.  For example, if you have someone who uses a particular floating add-on license every day and another person who uses it on occasion, it might be best to purchase one floating add-on for the every day user and a value pack of tokens for the occasional user.

NX token based licensing offers numerous advantages:

    Access to multiple products
    • More than 50 apps currently in the pool and growing
    • As new modules are added to the pool, you will be able to use them without additional effort from your internal purchasing team.
Extreme flexibility
  • Run the add-on module you need, when you need it
  • Run occasionally needed products without having to make a separate purchase
Useful for a variety of users
  • Electromechanical, Industrial Designers and Styling, Mechanical Designers, Tooling and Fixture Designers, Translators, etc.
Cost effective
  • Access to individual add-on licenses for all the products in the NX Product Engineering token pool would be cost prohibitive.

If your business can benefit from a broader NX portfolio without having to make a large investment — Token-Based Licensing is for you.

As a follow up to the BOM in Excel article, what would constitute a perfect system for managing Bills of Material (BOM) in a PLM system?

Let’s divide the capabilities of this ideal system into three categories; mandatory, essential and nice-to-have.

For the sake of definition, a Part is an end item in a BOM structure, and an assembly is a collection of Parts arranged in a BOM structure. Also, this discussion is restricted to eBOM; other types of BOM’s is a much larger topic.

Mandatory

  • Manage Parts making up the BOM
  • Manage Part Attributes such as Date Created, Owner, Make/Buy etc.
  • Manage Documents or Files associated with the Part (CAD, Drawings, Specs etc.)
  • Manage BOM structures of Parts, with indent capability
  • Handle version and revision levels for all Parts
  • Handle version and revision levels for all Assemblies
  • Allow for search capability on Parts and Assemblies
  • Enable reuse of existing Parts in new Assemblies
  • Facilitate comparison of current BOM structures
  • Allow for “where used” enquiries or reports
  • BOM structure export to facilitate external system integration
  • Collapse / expand indented levels
  • One BOM for all – accessible by all users

Essential

  • Manage lifecycle of BOM (In design, Released, In Production, etc.)
  • Distinguish between various types of Parts in Assemblies (Designed, Bought, Complete, In Work, Customer etc.)
  • Allow for comparison between various versions and revisions of BOM
  • Enable BOM view based on release date and different release configuration
  • Duplicate BOM (Save As) allowing for alterations and edits during the process
  • BOM templates for generic products
  • Allow for BOM variants and configurations
  • Based on configuration rules, resolve to exact BOM
  • BOM costing (roll up)
  • Launch BOM selections into Digital Mockup session
  • Enable clash and interference analysis

Nice to Have

  • Pictorial BOM
  • Search in BOMs
  • Part Classification to facilitate reuse
  • BOM weight roll up
  • Link BOM to Requirements
  • Allow for BOM visualization
  • Specific views dependent on user or context

Obviously, each of these requirements is a complete topic in of itself. Also, additional requirements may exist.

The Problem

Before computers, engineering designs where carried out by armies of draftsmen toiling over drawing boards in vast offices. Some may still express nostalgia for those days, but like all else, change came along. Today sophisticated computer programs allow engineering designs to be created in a full 3D virtual world with great degrees of precision. In the initial phases of the 3D modeling revolution there was a great debate over 2D vs 3D and because software vendors feared rejection over adoption, they included capacity to derive 2D drawings from the 3D model. The CAD programs essentially allowed the production of documents equivalent to what could be produced by a draftsman. But 3D CAD programs have continuing to improve in terms of functionality and capability; so much that all the information (and more) that used to be communicated via a 2D Drawing can be included in the single 3D model. Such an approach is far more efficient.

However, when asked organization after organization will admit to releasing and maintaining 2D Drawings for all sorts of purposes.

So, if technology has moved on beyond the 2D drawing, why are they still widely used in the industry?

The Technology

If you dig into the reasons why 2D Drawings still exist, various technical reasons are commonly offered:

  1. Dimensioning and tolerancing cannot be fully completed on a 3D model
  2. Tabled parts are difficult to create in 3D
  3. Consumers of drawings do not have the capability to view 3D
  4. 3D models cannot be printed out

Current Technology has an answer to all these problems:

  1. CAD software has core modules that can create a fully annotated model in 3D with all information included
  2. Design tables or configurations can achieve this very easily
  3. All major vendors offer viewers for 3D formats; the most basic of these are normally free.
  4. Viewers remove the need for printing; beside printed copies are uncontrolled and can lead to errors

It can easily be demonstrated that any technical objection can be overcome with correct tool deployment.

So, why do 2D drawings still exist?

The Culture

If you dig a bit further, other reasons start emerging from the shadows:

  1. We have always used drawings
  2. It would be difficult to retrain the shop floor
  3. Our suppliers don’t have the capability to use 3D models
  4. It would take years to redesign our processes

Finally, here are the true reasons why 2D drawings still exist and they are all cultural in nature. It is similar to the neighbor who trudges down the driveway in the snow and picks up a hard copy newspaper. Just sit up in bed and pick up a Smartphone!

So, how do you address the cultural issues?

The Change

Here is a high level journey from 2D to 3D

2D to 3D
  1. Technology – Choose the best technology
  2. Best Practices – Figure out how to take information in2D to 3D
  3. Impact – Evaluate impact to downstream processes
  4. Strategy – Design a strategy to replace 2D Drawings
  5. Planning – plan the transition and the OCM (more on that later)
  6. Implement – roll out the transition and goodbye to drawings

Here are some more critical elements of the journey

Best Practices – answer questions like Current information on Drawings? Critical vs Non-Critical? Common standard for GDT information? Company Standards?

Downstream Impact – In a complex organization, there are probably many users of 2D Drawings both within and without the organization. It is important to identify all these users before suddenly removing drawings!

Strategy – the various strategy components that must be considered include how to convert 2D information to 3D; technology purchase; repurpose downstream systems; training courses required; Project Plan; what to do with legacy data

Planning – As noted previously, the biggest obstacle to converting from 2D to 3D is cultural resistance. A well prepared organizational change methodology (OCM) and plan is vital. Considerations include communication, training, support and identifying champions.

Good luck!

Product and Manufacturing Information (PMI) consists of non-geometric data, that is attached directly to a 3D CAD model to define geometric dimensioning and tolerancing (GD&T), engineering and manufacturing specifications, dimensions, and text.  PMI is part of Model Based Definition (MBD) and together these two elements are a part of a Digital Twin.

Applying PMI to a 3D model can reduce or eliminate the use of 2D drawings and can be used downstream to perform tolerance analytics and coordinate-measuring machine (CMM) inspection.

PMI is a command within NX that gives you the ability to create/attach dimensions and annotations to define the 3D model, and requires model views similar to the views on a drawing.  These dimensions and annotations are associative to the 3D geometry, and if it is decided that a 2D drawing is required, then the PMI can be inherited from the 3D model and automatically applied to the drawing views.

We think of MBD and PMI as new technologies and 2D drawings as “old school,” but there are valid uses for a 2D drawing.  Given the ability in NX to quickly create 2D drawings with associative dimensions inherited from the 3D PMI… this gives you the best of both worlds.

The image below demonstrates what PMI looks like in a 3D model view, and the next image down demonstrates the inherited PMI in a 2D drawing view:

NX Realize Shape is a powerful and intuitive subdivision design tool that makes use of primitive shapes to create concept design models.  In the image below you can see a sphere has been chosen, but there are a number of other shapes to select from such as cylinder or block to name a few.

These primitive shapes can be placed over top of background data like sketches or even art work similar to what you see in the image above.  When a primitive shape is created, a cage is automatically created that surrounds the shape.  The shape can be morphed into designs by transforming that cage.  By selecting on, and dragging the cage elements (lines or points), you can mold the shape to fit the background image.

 

As seen in the image above, you can split a face into smaller faces (subdivide) in order to create more cage elements. This gives you greater control of the cage anytime more detail is required in a given area of your design.

By selecting cage elements (lines or points) and dragging them up or down, left or right, the concept designer is able to morph a simple shape into a complex form in a relatively shorter period of time versus having to work with .

Why do we promote the use of Realize shape?

Simple, this model represents the birth of the digital twin.  This digital twin is then used for detailed design, documentation, validation, simulation, and all the way to traditional or additive manufacturing… all within a single unified environment like NX… means you are going to use trusted data from concept to manufacturing… without requiring conversion or translation, and this is going to shorten your innovation lifecycle, getting you from concept to market faster!
