Description
Understanding Tolerances and tolerancing schemes is a very important part of Mechanical design .In most cases Tolerances are directly detrimental to the functional performance of a mechanical product.This course attempts to cover the key concepts in tolerance stackup , limits, fits and statistical tolerancing with examples . Tolerance stackup analyses are critical in applications where small changes in dimension of parts can have heavy consequences.What we will cover in the course?What is tolerance? What are sources of variation ?What are Fits , the nomenclature, types and Tolerance zonesHow to decode and interpret a Fit specification and convert it into limitsHow to Define a specification of a Fit for a specific applicationHow to do a simple tolerance stackup ? Generic procedure and factors to be considered?How to develop Loop Diagrams in Stackup ?Assembly shift in Tolerance analysisHow is assembly shift calculated Stackup with GD&T How to find Boundary conditions accounting for size and positional variationshow to derive the individual specifications in tolerance tableHow to develop the envelopes for GD&T controlsStatistical TolerancingWhy Statistical techniques are used? What is normal distribution What is difference between worst case and statistical analysisWhat is Process capability indexThe course is structured to provide learning in a methodical step by step way with clear explanations . Core Learning outcome is to provide a strong foundation concept in Tolerance analyses for mechanical Engineers in design and manufacturing.
