摘　　要：通过分析切削过程发现,切削力对刀具磨损的影响较大,不稳定的切削力是引起刀具磨损和失效的重要因素,尤其是硬质合金材质刀具。从加工工艺切削要素入手,减小切削力或提高系统对力的承载能力,减慢刀具的磨损速率,从而提高加工效率和加工质量,降低制造成本。在高速成型铣削加工薄壁工件内螺纹或内环槽时,受工件内径尺寸等条件限制,对切削力要求很高。结合硬质合金可换头内槽成型铣刀,从刀刃的对称和错齿结构入手,利用软件仿真和实验数据验证,可达到减小刀具切削力和优化刀具结构目的。Through the analysis of cutting process,it is found that cutting force has a great influence on tool wear.Unstable cutting force is an important factor causing tool wear and failure,especially for carbide cutting tools.Starting from the cutting elements of machining process,cutting force can be reduced or the bearing capacity of the system can be improved,and the wear rate of the tool can be slowed down so as to improve the machining efficiency and quality.The purpose of reducing manufacturing cost is to reduce the internal thread or inner ring groove in high-speed forming milling.Limited by the internal diameter of workpiece and other conditions,as well as the higher cutting force requirement of thin-walled workpiece,this paper combines with carbide interchangeable internal groove forming milling cutter manufactured by our company,starting from several structural factors such as symmetry of cutting edges and staggered teeth,and is proved by software simulation and experimental data.The new tool can reduce cutting force and optimize tool structure.
