Study of Carbon/Carbon Composite Material Surface Morphology on Ultrasonic Vibration Assisted Milling

Abstract:

Carbon/carbon composite is composite material using carbon fiber as reinforcement and carbon as matrix. However, it is the difficult-to-machine material due to some characteristics of the material. The thesis uses ultrasonic milling cutting in order to improve the surface quality. Surface quality becomes better with the improvement of milling speed; surface quality becomes poor with the increases of per tooth feed and cutting depth; S_ku increases after adding ultrasonic, and which explains that the mechanism of ultrasonic milling is different from that of ordinary milling; the increase of S_al indicates that surface defects of all kinds reduces in ultrasonic milling and the surface quality is better than that of ordinary milling.
