Abstract
The location accuracy of CNC machine tool is the key factor for its machining quality. The incremental error compensation algorithm was proposed by aimed at the accumulation and repeatability of location error of CNC machine tool. A universal incremental error compensation model was built,which was applied in the Aspheric CNC machine tool by Tangent Methoddeveloped in freedom. The experimental analysis shows that this incremental error compensation algorithm can improve the location accuracy of CNC machine tool by a wide margin.
