摘要
切削能绝大部分会转化为切削热,进而直接影响切削温度,因此研究切削参数对切削能的影响规律对切削温度的研究有重要意义。文章以新型硬质合金微坑车刀切削304不锈钢为例,通过理论计算结合切削实验,研究新型硬质合金微坑车刀在切削过程中切削参数对切削能的影响。结果表明,对剪切能影响最大的是切削深度,其次是切削速度,最后是进给量;对摩擦能影响最大的是切削速度,其次是进给量,最后是切削深度。
Most of the cutting energy is converted into cutting heat, which directly affects the cutting tem- perature. Therefore, it is important to study the influence of cutting parameters on cutting energy. In this pa- per, a new type of cemented carbide micro-turning tool cutting 304 stainless steel as an example, through theoretical calculation combined with cutting experiments to study the new carbide micro-pit turning tool in the cutting process cutting parameters on the cutting energy. The results show that the cutting depth has the greatest influence on the shear energy, followed by the cutting speed, and finally the feed rate. The cutting speed has the greatest effect on the friction energy, followed by the feed rate and finally the cutting depth.
