How to Create Creo PMI (GD&T) and Run a Tolerance Stack Up

3DCS for Creo - Using Embedded Geometric Dimensioning & Tolerancing PMI to Create 3D Stack Ups

Written by Priya Vijayakumar, DCS Variation Analyst - Creo Specialist

 

The integrated version of 3DCS in Creo can utilize any embedded GD&T (PMI) to quickly create tolerance analysis studies and give you the information you need to make quality decisions.

As an integrated tolerance analysis software, 3DCS utilizes Creo PMI to validate design objectives and simulate potential build issues. To use PMI in your tolerance analysis software, you first have to create it in Creo. For this tutorial, the terms GD&T and PMI are used interchangeably.

SOVA - Stream of Variation Analysis System for Multistage Manufacturing Processes

SOVA - Stream of Variation Analysis System for Multistage Manufacturing Processes

This piece is based on the work done by DCS Dimensional Control Systems in cooperation with Dr. Jianjun (Jan) Shi at the University of Michigan and Drs. Darek Ceglarek and Shiyu Zhou at the University of Wisconsin - Madison, with the support of a two million dollar grant from the Advanced Technology Program of the National Institute of Standards and Technology.

SOVA is a method of applying variation analysis as part of the design and manufacturing process to drive robust design in order to reduce costs in manufacturing. 

Developed in the late 90's and early 2000's and documented in the book "Stream of Variation Modeling and Analysis for Multistage Manufacturing Processes" (Jianjun Shi, 2006, CRC Press, ISBN 1420003909), it forms a basis for many of the programs DCS provides for customers and is similar to many process established by leading manufacturers in the automotive and aerospace industries.

Vector Loop Analysis and Stream of Variation Analysis - SOVA

What are Some Methods of Variation Analysis?

There are a number of different methods developed to both describe variation on models and drawings, as well as analyze and control the impact of that variation. 

In a typical assembly process, dimensional variation is affected by tolerances (including component and operationinduced tolerances) and operations. Tolerance Analysis is focused on tolerances and assumes operations are known. Dimensional Variation Analysis analyzes both tolerances and operations. For example, operation sequence or operation type is an analysis topic for Dimensional Variation Analysis.
