Tolerance Analysis
This discusses the importance of assigning tolerances to the dimensions. Tolerance analysis is the process of assigning suitable tolerances. Proper assignment of tolerances is important, because tight tolerances may result in good performance. However, when tolerances are overly stringent, parts may get rejected unnecessarily and production cost increases.
This unit discusses number of systems that help to allocate tolerances on various components. A brief discussion about the geometrical tolerance methodology is given.
The relationship between tolerances and manufacturing cost is explained.
The unit also discusses about the tolerance analysis which is the process of checking the tolerances to verify that all the design constraints are met. Tolerance analysis is sometimes known as design assurance.
The two methods of tolerance analysis - Worst-case Arithmetic Method and Worst-case Statistical Method.
