摘　　要：切削力和切削温度是衡量刀片切削性能,影响工件表面质量的两个重要物理量。本研究基于AdvantEdge有限元仿真软件建立了45号钢车削三维模型,研究了两种不同断屑槽刀片的切削力和切削温度变化规律,同时开展了相应的切削试验研究,并测量了刀片全寿命周期内的切削力和切削温度。结果表明,在研究切削参数范围内,具有较大前角的槽型A刀片的切削力和切削温度更低。本研究对刀片断屑槽结构优化设计,降低切削力和切削温度具有一定的指导意义。Cutting forces and cutting temperatures are two important physical quantities that measure the cutting performance of a blade and affect the surface quality of the workpiece. In this study, a three-dimensional turning model for 45 steel was established using the Advant Edge finite element simulation software. The study investigated the variation patterns of cutting forces and cutting temperatures for two types of blades with different chip breakers. Corresponding cutting experiments were also conducted, and the cutting forces and cutting temperatures were measured throughout the entire service life of the blades. The results indicate that within the studied cutting parameter range, the blade with groove type A, which has a larger rake angle, exhibits lower cutting forces and cutting temperatures. This study provides guidance for optimizing the design of blade chip breaker structures to reduce cutting forces and cutting temperatures.
