摘要

Abstract: Developments in 2 axis CNC aspheric machines and aspheric measuring instruments met the growing demand for high accuracy aspheric form machining, machine and machining accuracy have significantly improved in the last six years. It was found that spherical form could be machined and measured to a very high form accuracy, which was not possible to match for aspheric form due to the measurement term of absolute radius with form accuracy. Form correction software for use with the aspheric form measuring instrument (Form Talysurf) was developed by Rank Taylor Hobson (RTH) to eliminate waviness on the diamond cutting edge and radius error from true radius and to reduce aspheric form machining accuracy down to that of spherical form. !2
