Effect of ultrasonic vibration assisted drilling on cutting temperature and formed exit burrs

Abstract

In precision drilling process、 burr generation is a serious problem。 It is known that ultrasonic vibration (USV) can decrease cutting force and suppress formed burr height in drilling process 。 However 、 the effect of USV on burr mechanism in drilling process is not well understood 。 In this study 、 we focus on the effect of USV on cutting temperature and measured the cutting temperature in the drilling process for AISI 316 stainless steel plates with thermocouples。 As a result、 we found that the cutting temperature is decreased by the assist of USV。
