Abstract

Orthogonal cutting experiments of three kinds of hardness AISI 1045 steel are performed. The change of chip morphology with cutting conditions are investigated through metallurgical observation, and the critical cutting speed of adiabatic shear for AISI 1045 steel at different cutting depths, rake angles and hardness are given. In addition, the characteristic of chip deformation before the occurrence of adiabatic shear is also analyzed. The results show that the critical cutting speed decreases with the increase of cutting depth and hardness, but increases with the increase of rake angle. The deformation coefficient tends to one when the adiabatic shear occurring.
