Two-day course
Learn a simple procedure for determining the clearance/interference relationships between pairs of components that have been geometrically dimensioned and toleranced. The method is easily interpreted. Results can be quickly and easily checked, and revisions can be made with ease. If the work is interrupted, the analysis can be continued later without confusion. The mathematics involved in extracting and specifying assemblability tolerances for the mating features of conventionally-toleranced workpieces will also be reviewed.
This course is intended for personnel who are familiar with the principles, concepts and practices contained within ASME Standard Y14.5; and who now need to gain a further knowledge regarding an efficient method of performing tolerance stack-up analysis on the components of assemblies where conventional tolerance methods are specified, or a mix of both is specified.
