Optimization of Process Parameters About Automatic Drilling Holes System of Robot

以铝铝、钛钛和钛铝3种典型叠层构件为研究对象,利用专用试切台和钻孔质量检测仪,研究了机器人自动制孔系统钻削工艺参数。研究表明,铝铝和钛钛叠层构件机器人自动制孔系统可采用一次连续制孔方式实现高精度钻孔,对于铝铝叠层制孔系统采用主轴转速为4000r/min和进给速度为1200mm/min的参数较为合适。钛钛叠层制孔系统采用主轴转速为800r/min和进给速度30mm/min的参数较为合适。钛铝叠层构件自动钻孔时,当叠层厚度大于10mm时,制孔系统采用多次变主轴转速方式钻孔较好,且跟据各层材料选用工艺参数;当厚度小于10mm时,制孔系统采用一次连续方式钻孔,且以钛合金工艺参数进行钻孔。

Al/Al, Ti/Ti and Ti/Al etc. three typical laminated members are adopted as the target materials in this paper. Using a dedicated test cutting station and hole quality detector, process parameters about automatic drilling holes system of robot are studied. The results show that automatic drilling holes system of robot using Al/Al and Ti/Ti laminated members can achieve high-precision drilling holes through using a continuous way of drilling holes. Al/Al laminated member drilling holes system with a 4000r/min spindle speed and feed rate of 1200 mm / min parameter are more appropriate. Whereas Ti/Ti laminated member drilling holes system with a 800r/min spindle speed and feed rate of 30 mm / min parameter are more appropriate. During Ti/Al laminated member automatic drilling, when lamination thickness is greater than 10 mm, using multiple variable spindle speed drilling is better. Moreover, process parameters are selected according to layers material. When lamination thickness is less than 10 mm, drilling holes system uses a continuous manner, and drilling holes select the process parameters of the titanium alloy.
