Simulation and Response Surface Analysis of Cutting Performance of Ti(C,N) Based Cermet Tools

Le résumé fourni par la source

A simulation analysis was performed using Deform-3D 45 steel in order to improve processing efficiency and ensure the durability and accuracy of Ti(C,N)-based ceramic tools. Response surface analysis is used to compute and construct a secondary response surface mathematical model in which the cutting force and tool tip temperature vary according to the tool parameters (anterior angle,back angle,edge radius). Based on the analysis of variance and significance test of the response surface model, the effectiveness of the response surface prediction model is demonstrated in this study. The influence of tool parameters on cutting force and tool tip temperature during the turning of 45 steel with Ti (C, N) based ceramic cutting tools is analyzed to obtain the optimal tool parameters. The results show that the blunt radius has the greatest impact on cutting force and tool tip temperature. Proper reduction of the front angle, back angle, and blunt radius can effectively reduce cutting force and tool tip temperature. Ultimately, an anterior angle of 9°, a back angle of 8°, and an edge radius of 0.02mm constitute the ideal combination of tool parameters.
