Method for measuring offline error correction system and apparatus in automatic error compensation method of numerical control (NC) machine tools

摘要

The present invention relates to an automatic error compensation method for precision machining of an Irva numerically controlled machine tool, and more particularly, to a method and apparatus for measuring an off-line error correction system. GEOMETRIC ADAPTIVE CONTROL is an off-line geometric adaptive control system that can compensate for repetitive kinematic errors such as various error factors. After measuring the center of the ball with the touch probe, the volume error of the machine tool calculated on the computer ERRER) is compensated by the position control capability of the numerical controller.
