In this Question Line video, Jason explains surface vs. axis interpretation for positional tolerance at MMC and why ASME Y14.5 states to follow the surface interpretation when extreme form error is present.
In this Question Line video, Jason breaks down what the MMC modifier does, how bonus tolerance works, and why there is minimal benefit of applying MMC on a threaded hole.
In this Question Line video, Jason answers questions regarding True Position and how to calculate diametric deviations. He discusses the difference between "True Position" and "Position" and walks through the process of determining whether the part passes inspection.
In the Question Line Video below, Jason answers a student’s question regarding whether a feature of size can be designed to both Maximum Material Condition (MMC) and Least Material Condition (LMC) boundary constraints.
Can you use the MMC modifier and still ensure a minimum wall thickness? To answer this question, we are going to look at a drawing of a flywheel and compare how using the MMC modifier or the LMC modifier affects the minimum wall thickness.
