What is tolerance analysis?

Tolerance Analysis (or Geometric dimensioning and tolerancing – GD&T) refers to the study of the effects that the manufacturing variations of parts will have on the functions of the product. The norm ASME Y14.5 defines it as “a symbolic language used on engineering drawings and CAD models to define part geometry and communicate allowable variation“.  

This analysis can be done with different techniques, like: 

  • Worst case Approach
  • Statistical Approach 
  • Monte Carlo 

All three methods are available in Enventive Concept and Enventive 3D&T.

CAD models are perfect, real world is not

A product may work at the nominal in the CAD software, but manufacturing introduces imperfection that could compromise the performance of the product. On the other hand, precision is expensive. Choosing the right tolerance is not a trivial task even for simple assemblies.

Enventive Why Us

The sooner the Better

Some decisions made on the conceptual design phase are critical

Enventive Concept helps the designer in making optimal early-stage design decisions based on GT&D, working with a conceptual model. Enventive 3D&T also supports early-stage decisions, but this time based on imported 3D CAD models. Finally, Enventive 360 helps manufacturing coordinators, designers and project managers make better-informed decisions almost instantly when parts fail to meet specifications.

Enventive Product development process

Example

For a rotating machine, the gap between the stator and the rotor is very important. It will affect performance, safety and cost of the final product. The variation of this gap will be affected by a very large number of parameters. In this example, Eventive Concept will inform the designer about the relative importance of each contributor of the stack-up.

Our conceptual design abilities combined with Enventive Concept’s tolerance analysis and design optimization tools make Enventive Concept a superior tool for mechanical engineering design. One Enventive customer tells us that using Enventive Concept is 10 times faster than using their CAD system for his mechanical engineering design projects:
