Description

technical field

[0001] The invention relates to the fields of electromechanical integrated numerical control interpolation and contour error control, more specifically, an adjustment control system for curve contour error compensation and an error compensation method. Background technique

[0002] In recent years, with the rapid development of the manufacturing industry, multi-axis linkage CNC machine tools have been widely used in the fields of processing tools in aerospace, navigation, precision mold and other manufacturing industries due to their advantages of high speed, high precision and high quality processing. However, multi-axis linkage CNC machine tools often produce contour errors during machining due to mechanical transmission, electrical control, dynamic response characteristics of servo systems, and contour errors to coordinate the parameters of each axis to match each axis.

[0003] The adjustment control system and error compensation method of curve contour e...
