摘　　要：针对机床加工精度低和稳定性差的问题,提出以数控机床为研究对象,设计一种基于PLC的智能工业机电一体化机床控制系统。首先构建热误差建模算法,然后通过PLC实现热误差的补偿控制调节,可提高机床的加工精度和稳定性。具体实现为,由状态信息采集模块实现机床温度的测量;再在上位机数据处理模块中,通过建立机床温度与热误差同步测量系统,实现对热误差值的预测;再将预测值输入PLC控制模块,由PLC控制程序完成热误差预测值的补偿;并且对SIEMENS系统温度补偿功能的热误差补偿方法进行了研究。实验结果证明:在热误差补偿功能开启后,热误差最大值降低了78.9%。由此可知,本研究构建的机床控制系统可有效提高机床的加工精度以及稳定性,在实际应用中具有可行性。Aiming at the problem of low machining accuracy and poor stability, an intelligent industrial electromechanical integration machine tool control system based on PLC with CNC machine tool is proposed. The thermal error modeling algorithm is constructed first, and then the thermal error compensation control and adjustment is realized through PLC, which can improve the machining accuracy and stability of the machine tool. Specifically, the machine tool temperature is measured by the state information acquisition module;in the data processing module, the thermal error synchronization measurement system for the thermal error value is fed into the PLC control module, and the thermal error prediction value is compensated by the PLC control program;and the thermal error compensation method for the temperature compensation function of the SIEMENS system is studied. The experimental results show that the maximum thermal error is reduced by 78.9% after the thermal error compensation function is turned on. It shows that the machine tool control system constructed in this study can improve the machining accuracy and stability of the machine tool, and is feasible in practical application.
