An implicit enumeration approach to tolerance allocation in sequential tolerance control

The accuracy and precision of a manufactured dimension is largely dependent on the accuracy and precision of the technological processes selected for its execution. It is not unusual to have available several competing techno logical processes for execution of each manufacturing operation specified i n a process plan, where it is generally assumed that as the precision of th e technological process improves, the associated cost and yield of the oper ation increase. This paper presents an implicit enumeration approach to the selection of an optimum subset of technological processes required to exec ute a process plan under a sequential (or adaptive) tolerance control strat egy.
