Abstract
A contour error compensation method for computer numerical controlled (CNC) non-circular grinders is introduced. The compensation method collects set and actual positions of each axis from servo controllers during the dry run process and calculates compensation data for the interpolator of the CNC system. It can be executed quickly and iteratively without real grinding. It can also be integrated in existing CNC systems without modifying interpolation or servo control algorithms. Brief introductions to the servo controller simulation model and contour error displaying module when developing the compensation method are also given. Grinding results demonstrate high contour accuracy of a cam workpiece and efficiency of the compensation method.
