摘　　要：基于DEFORM 2D/3D软件,通过硬质合金平头倒角立铣刀进行高速铣削AISI4340合金钢的仿真实验,在主轴转速1270r/min、进给速度104m/min、切削深度0.1mm的参数下,利用刀具的几何磨损模型和仿真模型模拟了不同刀具磨损类型对切削力与切削热的影响以及刀具二次磨损的主要位置。研究发现,刃口钝化对切削力的影响最大,其次为前后刀面磨损、后刀面磨损和前刀面磨损;后刀面磨损对切削热影响最大,其次为前后刀面磨损、刃口钝化和前刀面磨损。本研究促进了刀具的结构设计的发展和加工工艺的更优选择。In this paper,through the simulation experiment of high-speed milling AISI4340 alloy steel with cemented carbide flat chamfered end milling cutter based on DEFORM 2D/3D software,under the parameters of spindle speed of 1270r/min,feed rate of 104m/min and cutting depth of 0.1mm,the effects of different tool wear types on cutting force and cutting heat and the main positions of tool secondary wear are simulated by using the geometric wear model and simulation model of tool.It is found that edge passivation has the greatest influence on cutting force,followed by both rake and flank wear,flank wear and rake wear.Flank wear has the greatest impact on cutting heat,followed by both rake and flank wear,edge passivation and rake wear.This reasearch promotes the development of tool structure design and better selection of machining process.
