本文讨论了不同难切削材料车削过程中冷却策略对热机械刀具载荷的影响。目的是描述如何控制作用在切削刃上的复杂载荷，以达到适合切削刀具材料和工件材料的不同组合的条件。作为介绍，本文介绍了使用硬质合金和高压润滑剂供应来车削 TiAl6V4 和 Inconel 718 时刀具温度、切削力和磨损行为的测量和分析。基于这些结果，评估了采用高压润滑剂供应和传统溢流冷却的 Inconel 718 车削过程中晶须增强切削陶瓷的刀具磨损行为。此外，本文还介绍了在低温条件（液氮和二氧化碳-雪）下用硬质合金车削 TiAl6V4 时的刀具温度、切削力和磨损行为的结果。低温条件下的测试结果将与高压冷却剂供应的结果一致。因此，可以将不同磨损机制的量限定在不同冷却条件下的总刀具磨损上，并显示它们如何受到具体影响。 (C) 2013 CIRP。
This paper deals with the influence of the cooling strategy on thermo-mechanical tool load during turning of different hard-to-cut materials. The aim is to describe how to control the complex of loads acting on the cutting edge to achieve suitable conditions for different combinations of cutting tool material and workpiece material. As an introduction, measurements and analysis of tool temperature, cutting forces and wear behaviour during turning of TiAl6V4 and Inconel 718 with cemented carbide and high-pressure lubricoolant supply are presented. Based on these results the tool wear behaviour of whisker reinforced cutting ceramics during turning of Inconel 718 with high-pressure lubricoolant supply and conventional flood cooling is evaluated. Additionally this paper presents results of tool temperature, cutting forces and wear behaviour during turning of TiAl6V4 with cemented carbide under cryogenic conditions (LN2 and CO2-snow). The results of the tests under cryogenic conditions will be brought in line with the results of the high-pressure coolant supply. Thereby it is possible to qualify the amount of different wear mechanisms onto the total tool wear under different cooling conditions and to show how they can be influenced specifically.
