CFRP材の穿孔加工における切削温度の影響

抄録

In this study presents the drilling on CFRP continuous 40 hole which is material thickness of 8 mm using drill tool was seven types of different coating and tool form by WC drill of tool diameter of 6 mm. We evaluated the relationship between the tool material and the cutting temperature was measuring with a thermocouple and an infrared thermometer. As the result, the cutting temperature has begun to rise due to the number of holes increases regardless of the difference of the tool shape and coating. After 40 hole drilling has reached about 120°C. In the case of diamond coating tool is low cutting temperature. Cutting chips affect in the cutting-temperature increase.
