摘要
传统的数控机床机械加工零件过程缺少对螺距综合补偿值计算,导致零件精度控制性能差、反向间隙补偿效果不好等问题。研究提出了基于目标补偿法的数控机床机械加工零件精度控制方法,建立了数控机床坐标系,对数控机床机械加工零件数据进行预处理。采用目标补偿法对螺距补偿后的综合补偿值计算,并设定阈值,控制各轴单周期的补偿量使用满足机床各轴进给速度的平滑性要求。运用目标补偿法对数控机床加工零件精度控制,完成数控机床机械加工零件精度的控制。实验结果表明,研究方法比传统方法加工零件精度控制效果好,可对反向间隙进行有效补偿,满足数控机床机械加工零件精度控制需求,具有一定的实际应用意义。
Traditional CNC machine tool machining parts lack of the calculation of the comprehensive compensation value of the pitch, which leads to the poor precision control performance of the parts and the poor effect of the reverse clearance compensation. In this study, the precision control method based on the target compensation method is proposed. The coordinate system of CNC machine tools is established to preprocess the data of machined parts. The target compensation method is used to calculate the comprehensive compensation value after the pitch compensation, and the threshold value is set to control the compensation amount of each axis in a single cycle to meet the smoothness requirements of the feed speed of each axis of the machine tool. The aim compensation method is used to control the precision of machining parts of CNC machine tools. The experimental results show that the research method is better than the traditional method in the precision control of machining parts, and can effectively compensate the reverse clearance to meet the requirements of the precision control of machining parts of CNC machine tools, which has a certain practical significance.
