Abstract
Precision manufacturing is a process to produce products with tolerances smaller than 1 part in 104 or 105. The process is based on dimensional precision, angular precision, form precision, surface roughness, kinematic precision, and surface layer alternations. There are sources of error in precision manufacturing that are enemies of precision processes. In this chapter, these sources are explored and a Markovian model is developed for evaluating process robustness and machine accuracy. An illustrative example is presented here in order to demonstrate the application of the model in industries dealing with precision processes.
