摘要:
同步超声复合电加工的关键问题之一是超声幅值的在线检测与加电间隙的在线控制;选用高速激光位移传感器测量工具头端面的振动幅值,并经数据采集卡输送至计算机中,基于LabVIEW开发监测与控制程序,通过RS232C串口对激光位移传感器公差比较器值进行在线调节,进而改变加电间隙;利用所完善的超声复合电加工系统,合理选择加工参数,对硬质合金进行超声复合电加工试验,结果表明了超声及其复合电加工技术在加工硬脆性和难加工材料的技术优势。

Abstract: Ultrasonic vibration amplitude on-line measurement and inter-electrode gap on-line controlling are the key issues of synchronizing ultrasonic compound electric machining. The vibration amplitude of end face of the tool head is measured by selecting high-speed laser displacement sensors, and then these data are transferred to computer by data acquisition card; based on LabVIEW development monitoring and controlling program, it can adjust tolerance comparator set point of laser displacement sensors on-line by RS232C, and then change the inter-electrode gap. Using the optimized ultrasonic compound electric machining system, selecting the reasonable processing parameters, the processing tests are conducted with cemented carbide. The results show that the ultrasound technology and compound electronic processing technology have technical advantages in machining hard and brittle difficult materials.
