摘　　要：针对薄壁零件在铣削加工过程中壁厚的补偿控制,提出一种对铣削机床的壁厚补偿响应周期测量方法。利用超声波探头检测工件厚度变化,壁厚数据通过串口通信发送给数控系统,数据采集软件对壁厚数据处理过程进行实时记录和保存。通过该方法可以有效获得零件加工过程中壁厚变化时壁厚的原始数据、过滤数据和写入数据的响应时间,可为壁厚补偿功能的优化和工艺参数的选择提供参考依据。In regard to the wall thickness compensation control of thin-walled parts in milling process,a measuring response period method of wall thickness compensation based on milling machine tool is proposed.The ultrasonic probe is used to detect the thickness change of the workpiece.The wall thickness data is sent to the CNC system through serial communication.The data acquisition software records and saves the wall thickness data processing process in real time.By the method,the response time of original wall thickness data,wall thickness filtering data and wall thickness writing data can be effectively obtained when the wall thickness changes in the process of parts processing,providing reference basis for the optimization of wall thickness compensation function and the selection of process parameters.
