In order to investigate the energy loss of chipbreaker geometric parameters on turning Ti6Al4V titanium al-loy,a simulation model of turning Ti6Al4V titanium alloy with PCD chipbreaker tool is established based on ABAQUS simu-lation software,and the effect of trapezoidal chipbreaker parameters(front angle α,rib width br,counter chip angle θ)on cutting force and tool tip temperature is investigated by single-factor method.Multi-indicator orthogonal experiments are es-tablished,and the degree of influence of each factor on performance and energy loss is investigated by using the extreme difference analysis method.Analyzing the experimental results,it is concluded that the cutting performance is best and ener-gy loss is lowest when α =15°,br =0.07mm and θ =25°.
