Improve Processed Surface's Precision of Optical Elements by Grinding under Kinematic Program Control

Abstract

Based on the definitions of the local coating coefficient, the average local coating coefficient and the speed coefficient in grinding of optical elements and on theory of multibody kinematics, the software for kinematic program control during grinding process of optic elements was worked out in the Hanoi University of Technology. Using this software some research results for increasing processed surface's precision of optic elements by grinding under kinematic program control were presented in this paper.
