Tolerance Stack Mechanical Tolerance Analysis Stack Analysis Electronic Design Seminar Series Tolerance Stack Analysis Seminar Goal • Provide an understanding of the various methods of performing mechanical tolerance stack analysis. So that you can: 1. Select the appropriate method of analysis for the application 2. Perform the analysis correctly. Electronic Design Seminar Series Tolerance Stack Analysis Seminar Overview • Section 1: Tolerancing Basics • Section 2: Worst Case (non-statistical) Tolerancing Overview • Section 3: Rapid Statistics (Relevant) Review •Section 4: Tolerance Allocation: “Risk of Misassembly” Method •Section 5: Probability Method of Statistical Tolerancing •Section 6: Statistical Tolerancing using Monte Carlo Simulation •Section 7: Summary: Choosing the Right Method Electronic Design Seminar Series Tolerance Stack Section 1: Analysis Where Tolerances Should Come From • Process Knowledge (I.e., Knowledge of Process Capability): This requires a variation data feedback loop between the manufacturer and the design engineer. •Dimensional Requirements to Ensure Proper Function of the Finished Product: This requires analysis of tolerance schemes and values. •Design Guidelines. •Etc. •PUTTING A TOLERANCE ON A DRAWING DOES NOT MAKE IT SO!
