Understanding Dimensional Variation in Common Mechanical Processes, How IT differs in plastic Parts, and Minimizing It
This paper breaks down the causes of variation in mechanical parts into its constituents. It then distinguishes the variation in other processes from plastic parts where the material selection, design rules, tooling and processing have a much greater effect on variation. Once these differences are understood, two very powerful CAD based tools are introduced to be used to minimize the tolerance build up.
Understanding Tolerance Build Up In Mechanical Parts & Assemblies – and Dealing With Them - Historical And MBD Approaches
For any product to be assembled in mass production, it is important that any component in the assembly fit with rest of the components regardless of the batch or source of production and meet the assembly and functional needs.
