More options in statistical tolerance analysis

An Elite Consulting product story
Edited by the Engineeringtalk editorial team Jul 24, 2008

CETol 6sigma is built on 3D variation behaviour modelling technology which has a fast direct solver and is fully integrated with Pro/Engineer, Catia V5 and SolidWorks.

Until now, anyone wanting to purchase Sigmetrix CETol 6sigma statistical tolerance analysis software was restricted to a high end 3D package for Pro/Engineer or Catia.

That has all changed with the introduction of three cost-effective alternatives.

For those who want a simpler tolerance analysis system, Sigmetrix in conjunction with Parametric Technology Corporation (PTC) has recently released the Tolerance Analysis Extension for Pro/Engineer.

This is a cost-effective easy-to-use solution for doing one dimensional statistical analysis that is available for Wildfire 4.0.

Elite Consulting, the tolerance analysis consultancy and reseller of Sigmetrix software in the UK, is offering a free demonstration to anyone who may have tolerance-related issues or has a six-sigma quality programme.

Ray Ellender, Managing Director of Elite Consulting, said: "Using advanced mathematical solutions, CETol accelerates tolerance optimisation to achieve robust designs ready for manufacturing".

"It enables manufacturers to accelerate product quality maturity and promote engineering best practices throughout the process of product lifetime management".

"CETol 6sigma can produce the most accurate, comprehensive and reliable answers using native Pro/Engineer Wildfire geometry".

"It helps improve product quality and gain design insight by understanding the true, derived relationship between critical product requirements and design input variables".

In addition Sigmetrix has released two new versions of CETol: V8.0 for SolidWorks and V8.1 for Pro/Engineer.

With V8.0, CETol works directly on the SolidWorks model in 3D to calculate either a worst case or a statistical tolerance stack-up.

This software enables design engineers to match tolerances to manufacturing capability and predict yields at the design stage.

CETol V8.1 for Pro/Engineer has a number of enhancements including the ability to animate the effects of tolerance changes.

It can provide flush and gap measurements and includes a model advisor to help the modelling process.

According to Ellender: "Unlike other tools in the industry that rely on slow Monte-Carlo analysis, CETol 6sigma is built on 3D variation behaviour modelling technology which has a fast direct solver and is fully integrated with Pro/Engineer, Catia V5 and SolidWorks - allowing for precise sensitivity, statistical and worst case scenario tolerance analysis".

"You could improve quality and reduce costs by having CETol 6sigma".

"However, if you don't want to have your own copy of the software, but you do have a tolerance problem to solve, give us a call and we will do the analysis for you".
