This study has been conducted to analyze the effects of turning the Inconel X-750 superalloy, which is a member of nickel-based superalloy family that is frequently preferred in aerospace and nuclear energy industries in particular, under Minimum Quantity Lubrication (MQL), cryogenic liquid nitrogen (LN2) and carbon dioxide gas (CO2) cooling/lubrication conditions, with different cutting speeds (Vc= 65, 95, 125, and 155 m/min), constant feed rate(f=0.1 mm/rev), and cutting depth (a=0.5 mm) parameters, on the processability of Inconel X-750, hence on the surface integrity. In this context, the results obtained from the tests have been comparatively examined through surface roughness, tool wear, and chip formation. Comparison results show that the cryogenic CO2 method has generally provided the best surface roughness, tool wear values. MQL method has provided the best chip formation.

切削条件对Inconel X-750高温合金车削表面质量的影响

进行了这项研究来分析车削Inconel X-750高温合金的影响,该合金是镍基高温合金家族的一员,该合金在航空航天和核能工业中尤其是在低温下的最低润滑量(MQL)下通常是首选的液氮(LN 2)和二氧化碳气体(CO 2)的冷却/润滑条件,具有不同的切割速度(Vc = 65、95、125和155 m / min),恒定进给速度(f = 0.1 mm / rev) ,以及切削深度(a = 0.5 mm)参数,这取决于Inconel X-750的可加工性,因此也取决于表面完整性。在这种情况下,已经通过表面粗糙度,工具磨损和切屑形成对从测试中获得的结果进行了比较检查。比较结果表明,低温CO 2该方法通常提供了最佳的表面粗糙度,工具磨损值。MQL方法提供了最佳的切屑形成。
