About Tolerance Design Training
Who is Tolerance Design Training for?
Tolerance Design is most often used by Product Design Engineers and their management. In our course, Texas students learn:
Tolerance Design Training Course Overview:
How many billions of dollars do you suppose have been lost due to tolerances being either too tight or too loose? If they're too tight, manufacturing cost is unnecessarily high. And often the relationship between Product Engineering and Manufacturing is strained, damaged, and contentious. If tolerances are too loose, warranty cost will be high and relations with external customers will be damaged exposing your organization to market share being stolen by competitors. Who wants to live this way? Certainly, most of the companies we visit do no tolerance design at all relying on arbitrary block tolerances. It is absolutely certain that block tolerances are costing you. Probably a 6-7 digit annual cost depending on the size of your company.
The primary focus of our 1-day Introduction to Tolerance Design is conveying how to improve profit by setting tolerances at the optimal balance between external (warranty) cost and internal manufacturing cost. Sometimes this is attained by tightening tolerances. Sometimes it is attained by loosening them. Through presentation, examples, and hands-on exercises, Texas students will learn through doing the following in a highly interactive and fun setting:
 | | Prioritize. Tolerances based on their ability to impact product functionality / performance through application of Design of Experiments. This introductory course is limited to 2-factor designs; 2 levels of tolerance variation one high and one low. We do offer an Advanced Tolerance Design class to address 3-factor designs. |
| | Analyze. Cost implications associated with changing tolerances through constructing quality loss functions, calculating average quality loss, and conducting cost benefit analysis. |
| | Choose. Which tolerances to tighten or loosen and by how much. |
Prerequisites. Basic:
| | Knowledge of Product Design / Engineering |
| | Math: Algebra, Summations |
| | Excel |
Details.
| | All Texas students receive a binder of slide print-outs. |
| | Texas students will also be asked to evaluate the class. |
| | Comprehension will be measured with a quiz. Passing grade is 80%. Texas students scoring less will receive a call from their instructor to review weak points. |
| | Once understanding is confirmed, certificate proofs will be emailed for error-checking. |
| | Certificates will then be printed and delivered by normal mail. Certificates are individually serialized with no expiration date although annual refresher training is recommended. |
Schedule. The day is usually 8am-3pm including time for breaks and followed by a quiz. Lunch is between 30-60 minutes depending on client preference.
