The Most Powerful Tolerance Analysis Software
Manufacturers across the globe reduce defects and improve their products with 3DCS software for Tolerance Analysis
OEM's and Suppliers across the globe use 3DCS to improve their product quality while reducing manufacturing costs. As a part of Design for Manufacture and Assembly (DFMA) as well as Model Based Definition (MBD), 3DCS is a powerful tool for simulating both assembly processes and part tolerances together to validate design specifications, improve design through iterative changes and root cause build issues.
Why Use a CAD Integrated Software?
Integrated CAD tools provide a streamlined approach to analysis that improves adoption, training and process implementation. With the ability to open 3DCS for CATIA V5 in the CAD platform, and utilize PMI, FTA, and CAD characteristics, implementation of 3DCS as a tolerance analysis tool becomes easy to learn and apply. With an integrated modeling approach, 3DCS saves the analysis data in the model files, letting users manage their CAD model in leading PLM systems like Teamcenter, Windchill, Enovia and 3DEXPERIENCE and automatically bring their tolerance analysis along. This answers the challenge of both file management and version control.
The Leading Tolerance Analysis Solution - What is it?
3DCS Variation Analyst CAA V5 Based (3DCS for V5) is an integrated software solution in CATIA V5 that simulates product assembly and part tolerance 3D stack-ups through Monte Carlo Analysis and High-Low-Mean (Sensitivity) Analysis.
Activated as a workbench in CATIA, 3DCS for V5 simulates part and process variation with three kinds of simulation to provide an understanding of your product's quality. This can be viewed as an estimated percent that will be out of specification, giving you an understanding of your risk, as well as current Ppk, Cpk and a variety of other metrics.
In addition, 3DCS lists the contributing features for every measurement in your model, giving you an understanding on where the variation is coming from, not just what it is.
Model Assembly Process and Part Tolerances - How does 3DCS work?
3DCS for V5 uses three methods of simulation;
By accurately modeling the assembly, you can see how both the assembly process and the part tolerances contribute to the product's overall variation. Together, this creates a virtual prototype that can be used to make decisions about design changes and tooling while reducing non-conformance that leads to scrap and rework.
Gain Greater Insight Into Your Design
Simulating products in a digital environment gives engineers the ability to account for variation in key areas; reducing rework, non-conformance and scrap at final assembly early in the design phase when changes are least expensive.
In addition to this, specifications deemed less critical can be relaxed, increasing tolerances and allowing the use of less expensive manufacturing processes. Creating 3-dimensional tolerance stack-ups let engineers know where to focus when measuring and designing, and the ability to create what-if studies allow them to determine solutions that include both process and part tolerances to keep quality high and costs down.
The 3DCS technology brought our commitment to product quality and safety by design to an even higher level. The tool not only can quantify our technical decisions but truly helps our IPD teams to numerically and visually discuss spatial dimensional variations and its management early in the design phase.
