Experimental Study on Ultrasonic Vibration Drilling of Titanium Alloy Micro-hole

摘要

Through the analysis of the basic principles of vibration drilling and vibration drilling process, in the drilling device and the cutting parameter sides, combined with the actual structure of the workpiece as well as the ultrasonic vibration drilling processing methods to elaborate, using the ultrasonic vibration drilling device to carry out the TC4 titanium alloy micro-hole drilling test. The test prove that selecting reasonable cutting parameters can solve the problem of drilling TC4 titanium alloy micro-hole that size is Φ1.5mm × 12mm, fully reflects the superiority of the ultrasonic vibration drilling. A new method was afforded for titanium alloy micro-hole drilling.
