Research on Error Compensation Technology for CNC Machining

Aiming at the thermal error problem in the procedure process of CNC machine, this study develops a new thermal error compensation technology. First, spindle and linear axis error are analyzed and measured. Then, a comprehensive error compensation model are proposed, which combined with spindle and linear axis. Finally, we use an example to illustrate the proposed method. Experimental results have shown that the proposed approach is able to reduce the influence of the thermal error on machining precision
