一、前言 随着我国科学技术和各项工业的迅速发展,不锈钢的应用范围逐渐广泛。在机械、航空、化工、食品、轻工等工业中,各种零件、部件采用不锈钢材料已日益增多,其中奥氏体不锈钢应用最广,是具有代表性的一种。这种钢虽有强度高、耐高温、耐腐蚀和非磁性等特性。然而,由于其物理机械性能与一般碳钢不同。因此在掌握其切削性能方面还是不很完善的。一般说来,不锈钢被认为是切削加工性能较差的金属材料,它比低合金钢更难切削,在加工时切削力大,切削
I. Introduction With the rapid development of science and technology and various industries in our country, the application range of stainless steel is gradually expanding. In the machinery, aviation, chemical, food, light industry and other industries, a variety of parts, components of stainless steel has been increasing, including the most widely used austenitic stainless steel, is a representative of a. Although this kind of steel has high strength, high temperature resistance, corrosion resistance and non-magnetic properties. However, due to its physical and mechanical properties and general carbon steel is different. So to master the cutting performance is still not perfect. In general, stainless steel is considered to be a poor machinability machining metal material, it is more difficult to cut than low-alloy steel, machining cutting force, cutting
