Study on process and performance of laser heating assisted micro cutting of alumina ceramics

摘要

For the study of alumina ceramic micro turning machining performance, using (IPGPhotonis) fiber laser heating assisted cutting. Due to the high strength and hardness of the alumina ceramics, using cubic boron nitride (CBN) tool for turning experiment. The effects of different processing parameters such as laser power, spindle speed and feed rate on the surface roughness and tool wear were studied. Compared with the experimental results obtained by laser heating and non-laser heating, we found that the surface quality is improved by laser heating, and the service life of the cutter is prolonged.
