【 摘 要 】

The error compensation of Micro Four Axis CNC milling machine is mainly about the basic principle of error compensation and the realization of error compensation. It also analyzes the problems that should be paid attention to in error compensation, so as to improve the effect of error compensation. The method of superposition additional instruction and direct calculation for correcting NC instruction is expounded. According to the error modeling of the four axis CNC milling machine, the theoretical and practical relation between the tool path to the NC instruction, the theory and the actual relation of the NC instruction to the tool path are given by the direct calculation method, and the calculation of the actual numerical control instruction is made by using the relation formula, which provides the software compensation information for the micro four axis CNC milling machine.
