摘　　要：为了研究面铣刀铣削钛合金时背吃刀量、铣削速度和进给量对刀齿所受切削力的影响,建立面铣刀铣削钛合金的模型。采用单因素实验法,基于ABAQUS有限元仿真软件对所建模型进行铣削仿真,在不同背吃刀量、铣削速度和进给量的条件下,分别对刀齿切削力的变化规律进行分析。研究表明:面铣刀铣削钛合金时,背吃刀量的改变对切削力影响程度最大。在中高速铣削条件下,使用小背吃刀量和大进给量,可以降低切削力,提高刀具寿命。In order to study the influence of back-cutting amount,milling speed and feed rate on the cutting force of cutter teeth when milling titanium alloy with face milling cutter,a model of face milling cutter milling titanium alloy is established.Adopting the single factor experiment method,based on ABAQUS the built model is simulated.Under different milling conditions of back-cutting amount,milling speed and feed rate,the changing law of cutting force of cutter tooth is analyzed.It is shown that when milling titanium alloys with face milling cutters,the change in the amount of back-cutting has the greatest impact on the cutting force.Under the conditions of medium and high-speed milling,small back-cutting and large feeds should be used for milling to reduce cutting force and improve tool life.
