A New Interpolation Algorithm for Ultra-Precision CNC Machining

摘要

In Optical design, aspheric lens are frequently adopted because optical system can be simplified and aberration of light can be reduced. Most conventional CNC machines support only the functions of straight line and circular interpolations and they can not machine aspheric surfaces. This paper introduces a new interpolation algorithm which is designed for ultra-precision machining. It can process general curves instead of pre-processing them out of CNC. Implementation of those algorithms is introduced in detail and some examples are given.
