Study on the Combined Machining Technology of Sawing and Grinding for Drilling Aramid/Epoxy Composites

Abstract:

Aiming at the problem of poor machinability in conventional drilling of aramid/epoxy composites, the formation reason for fuzzing damage was analyzed. In order to obtain better machining quality, a combined machining technology based on sawing and grinding mechanism was proposed and the corresponding drilling tools were developed. Drilling experiments were conducted to explain the machining performance of the drilling tools. The results show that the sawing drilling tool with negative rake angle can effectively restrain fuzzing damage and the sawing-grinding drilling tool decreases the thrust force about 20%~55% with electroplated diamond abrasives. The combined machining technology of sawing and grinding achieves damage-free machining quality in drilling of aramid/epoxy composites.
