The AGPM Control Error Compensation Research

Abstract

The article contraposed AGPM (Aspherical Grinding Polish Machine) co ntrol system, proposed an error prospective compensation method that based on the HM theory, combined threshold constraint technology and expectation evaluation ideas of statistics. Meanwhile, the corresponding control error compensation model was establis hed. By experimental verification, the error compensation method can effectively solve the problem that error compensation of CNC, it also provided a new attempt for error compensation of NC system and its similar.
