Design of Adaptive Machining Control System Based on Constant Torque
Cutting force has a significant impact on machining quality and efficiency.In response to the dif-ficulty of directly measuring cutting force,an adaptive machining control technology scheme with constant spindle torque is proposed with the goal of efficient and stable cutting.Based on the relationship between e-lectromagnetic torque and cutting parameters,an adaptive milling machining model based on spindle motor vector control was established by Simulink.With constant electromagnetic torque as the target,fuzzy adap-tive control strategy was adopted to carry out simulation experiments on the machining model,and an adap-tive machining system was developed for cutting experiments.Both experimental results show that the pro-posed method has higher machining efficiency,better machining stability and lower spindle load fluctuation than the traditional PID adaptive machining method.A virtual-real adaptive machining control system is es-tablished,which effectively reduces the development cost of the system.The virtual-real experimental re-sults confirm each other and improve the reliability of the proposed technical scheme.The scheme has good engineering reference value.
