This two-day course teaches participants how to solve assembly stacks using both traditional and Six Sigma methods. We highlight the design risks that are associated with the classical methods of tolerance analysis, and introduce Six Sigma methods that will eliminate these risks.
The goal of the Six Sigma techniques is to teach the participants how to assess the manufacturing and design risk of their tolerances. This risk is quantified in terms of manufacturing defects and assembly defects. These methods are unique because they allow the participants to optimize their designs by making trade-offs between assembly defects and manufacturing defects.
This is a lecture course, with many opportunities for participants to work on problems. We walk the participants through each of the tolerance analysis and allocation methods. After they master each method, we show them an Excel® spreadsheet that automates each method. This course is unique because it teaches participants to apply Six Sigma techniques to predict their design and manufacturing risk before they build parts.
Participants receive an Excel® spreadsheet to automate the tolerance analysis and allocation methods and a participant guide as a hands-on reference.
It is recommended that participants bring a laptop, which has the Excel® software loaded onto it. Additionally, participants must bring a calculator with square and square root functions.
