过去学习苏联金属切削原理时,我们曾经对切屑形成过程中某些现象加以综合分析研究。由于车削与拉削较容易入手,故本文即以苏联学者的研究以及目前国内有关单位对车削及拉削所做试验为依据,把常用的45号碳素钢与20X钢的金相组织对加工表面光洁度的关系,以及加工表面在切削过程中形成不平度的关系加以初步探讨,以供同志们参考与指正。采用车削与拉削试验的理由如下:(1)车削过程的切削原理较易理解,在实际
In the past to learn the principle of metal cutting in the Soviet Union, we have conducted a comprehensive analysis of some phenomena in the chip formation process. As turning and broaching easier to start, so this article that the Soviet scholars and the current domestic relevant units of the lathe and broaching done by the test, the commonly used 45 carbon steel and 20X steel metallurgy on the processing Surface finish, as well as the processing surface roughness in the cutting process of the relationship to be initially discussed for comrades reference and correction. The reasons for using the turning and broaching tests are as follows: (1) The cutting principle of the turning process is easier to understand. In practice
