The main objective of the project is to analyze the minimum requirements of cryogenic cooling in the milling of titanium alloy Ti6Al4V to reduce high cutting temperatures by an improved coolant supply using CO2 cooling. The tool wear will, with similar productivity compared to production with conventional emulsion or oil cooling, be slowed and reduced. Through specific CO2 snow cooling the cutting zone is cooled in a way that thermochemical wear can be excluded. Furthermore, it is required to analyze the impact of changes in the thermo-mechanical load using cryogenic cooling on the operational behavior of coated carbide tools for the machining of titanium alloy Ti6Al4V. Complementarily, ecological and economically studies concerning the useful application of cryogenic cooling are be carried out.

该项目的主要目的是分析钛合金Ti6Al4V铣削中低温冷却的最低要求，以通过使用CO2冷却改善冷却剂供应来降低高切削温度。与使用常规乳化液或油冷却的生产相比，在具有类似生产率的情况下，刀具磨损将被减缓和减少。通过特定的CO2雪冷却，切割区以一种可以排除热化学磨损的方式冷却。此外，需要分析使用低温冷却的热机械载荷的变化对用于加工钛合金Ti6Al4V的涂层硬质合金刀具的操作行为的影响。作为补充，还开展了有关低温冷却有效应用的生态学和经济学研究。
