| Abstract: | In this paper the effect of in-process measurement error, machining error and the machining target on machining result is investigated. The optimization mathematical model of machining target, the safety margin and the applications of machining target in grinding of inner race of bearings are given. It is concluded that the machining target should properly deviate from middle point of tolerance zone in order to reduce the rejections and the machining cost. |
