Error Model for Grinding of Noncoaxial Aspheric Based on Kinematics for Multi-Body System

Abstract:

The error compensation is an essential issue for improving the accuracy of the machining process. To solve the error compensation for parallel grinding of the noncoaxial aspheric lens, a kinematics model of six-axis ultra-precision machining system has been developed in the present study. Based on the theory of multi-body system, a kinematics errors analysis is presented. The interpolation errors of the parallel grinding method are discussed according to the kinematics errors analysis. Simulation results show that the rotation errors of the grinding system are crucial factors affecting the accuracy of the machining process.
