The Leading Tolerance Analysis Solution - What is it?

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 a variety of metrics from Cp, estimated percent out of specification, range of variation, and more. These analyses give you an understanding of your risk of product failure as well as the sources of variation to hone in on the source of the problem.

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.

Model Assembly Process and Part Tolerances - How does 3DCS work?

3DCS for V5 uses three methods of simulation;

1. Monte Carlo Simulation

2. High-Low-Median (Sensitivity analysis) 

3. GeoFactor (RSS equation) Analysis

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.
