摘要:
本文首先阐明了金属切削中热电效应的基本原理。接着,通过试验,按刀具一工件自然热电偶的伏—安特性,定量分析了切削区热电流的大小。然后,采取施加与不施加外加电流,为抑制刀具的磨损进行了一系列试验。由采用高速钢刀具(W18Cr_4V)切削不锈钒钢管的试验可得出如下结论:绝缘法优于普通切削法,而各种方法中又以热电流补偿法效果最佳,施加同向电流法效果次之。最后,通过机床电阻的测量,使我们获得了有关改进机床结构设计,选择机床最佳主轴转数,发展非金属刀具材料与硬质合金涂层刀片等问题一系列新的启示。
Abstract:
This paper deals first with the basic principles of the thermo-electric effect in metal cutting. Through repeated tests, the magnitude of the thermo-electric currents in cutting zone has been analysed quantitatively. On basis of the V-A property of the tool-work natural thermocouple. Then, a series of tests with and without externally applied currents have been made to prevent the tool wear by means of various methods. From the result of the experiment, the following conclusions could be drawn, while turning stainless steel pipes (1Cr18Ni9Ti) with high speed steel (W18Cr4V): the insulating method is superior to the general cutting method, the effect of thermo-electric compensating currents applied externally is the best in alI various methods and subsequently it is shown that the externally applied current flows in the same direction as the generated thermo-electric current. Lastly, by actual measuring the external machine resistance, we may obtain a series of new suggestions about the improvement of the machine structure design, thechoice of the optimum revolution of machine spindle, the development of the non-metallic tool materials and the coated carbide inserts etc.
