Error Compensation of Aspheric CNC Machining by Tangent Method
摘要
Abstract
The paper contraposed tangent method principle of aspheric CNC machining speed inter-polation,an error predictive compensation method was proposed,that was based on the HMM theory, combining threshold constraint technology and expectation evaluation ideas of statistics.According to the method,the paper established “aspheric CNC machining by tangent method”error compensation model.Through the practical applications and the experimental analysis the error predictive compensa-tion method can solve the error's problem of CNC machining effectively,the method can be applied to interpolation principle of the control system,and applied other interpolation principles.The error pre-dictive compensation method proposed is a new attempt in the field of error compensation research,in the long run,it will have good prospects for development and a more broad space for applications.关键词
