摘要
针对零件的材料特性和结构特点,开展精密群小孔数控钻削和检测工艺实验,研究影响小孔加工精度和效率的主要因素,研究微小群孔精密高效的检测方法。通过研究,采用Visual Basic6.0开发了多孔网栅钨膜片交互式孔位自动编程系统,采用热装式夹持系统和数控钻削技术加工多孔网栅钨膜片,并采用超声波清除毛刺,单孔加工时间约2s,单只钻头能加工1000多个孔,小孔加工精度和效率均满足要求;采用影像仪检测技术,能够满足多孔网栅钨膜片小孔检测的精度和效率要求。
Based on the material properties and structure of parts, the machining experiments of NC drilling and detecting process were developed. Through the experiments, the main factors were examined which influence machining quality and efficiency. The detection methods of multiple micro holes were investigated. Finally, an automatic programming was developed by use of Visual Basic6.0.The grid of tungsten foils were machined by use of thermo grip and NC drilling. Simultaneously, the burrs were wiped off by use of equipment of ultrasonic. The results showed that the process time of drilling was about 2 seconds and a single bit could drill more than one thousand holes. The quality and efficency all meet the requirement. The computered radiography is suitable for rapid and precise detection of the grid of tungsten foil.
