摘　　要：为研究机夹车刀在切削过程中,刀具所受的应力、应变、稳定等因素对刀具磨损、破损的影响,在Pro/ENGTNEER软件中建立了机夹车刀刀片、刀体的实体模型,再将机夹车刀装配组件文件导入到ANSYS软件中,采用有限元分析法对刀具的进行了切削力和切削热分析.通过分析得到刀尖和主切削刃靠近刀尖部分的应力、应变和切削温度最大,此处是刀具最容易发生磨损和破损失效,此研究对于提高刀具的耐用度、使用寿命和缩短产品的研发周期、制造等提供了参考.In order to study the tool wear and dilapidation from the effects of stress, strain, stability and other factors in cutting process, this paper built the tool models of blade and body with the application of Pro/ENGINEER software, and then analyzed the cutting force and cutting heat by using finite element method after transferring the assembly file into ANSYS software. Through the finite element analysis,the stress, strain and cutting temperature of blade tip and the portion of cutting edge near the nose are larger, where the tool mostly prone to breakage and wear failure. This study provides a reference for improving the durability of the tool, the service life, and shortening the cycle of product development and manufacturing.
