Although Inconel 718 is an important material for modern aircraft and aerospace, it is a kind material, which is known to have low machinability. Especially, while these types of materials are machined, high cutting temperatures, BUE on cutting tool, high cutting forces, and work hardening occur. Therefore, in recent years, instead of producing new cutting tools that can withstand these difficult conditions, cryogenic process, which is a heat treatment method to increase the wear resistance and hardness of the cutting tool, has been applied. In this experimental study, feed force, surface roughness, vibration, cutting tool wear, hardness, and abrasive wear values that occurred as a result of milling of Inconel 718 material by means of cryogenically treated and untreated cutting tools were investigated. Three different cutting speeds (35-45-55 m/min) and three different feed rates (0.02-0.03-0.04 mm/tooth) at constant depth of cut (0.2 mm) were used as cutting parameters in the experiments. As a result of the experiments, lower feed forces, surface roughness, vibration, and cutting tool wear were obtained with cryogenically treated cutting tools. As the feed rate and cutting speed were increased, it was seen that surface roughness, vibration, and feed force values increased. At the end of the experiments, it was established that there was a significant relation between vibration and surface roughness. However, there appeared an inverse proportion between abrasive wear and hardness values. While BUE did not occur during cryogenically treated cutting tools, it was observed that BUE occurred in cutting tools which were not cryogenically treated. Also, in this study, the statistical validity of the experimental values was tested with the help of second-order equations and analyses of variance (ANOVA). R² values obtained as 99.14%, 99.76%, and 97.98% for vibration, surface roughness, and feed force values were modeled statistically with the help of second-order equations, respectively.

Inconel 718 虽然是现代飞机和航天的重要材料，但它是一种材料，众所周知，它的可加工性低。特别是，在加工这些类型的材料时，会出现高切削温度、刀具上的 BUE、高切削力和加工硬化。因此，近年来，代替生产能够承受这些困难条件的新切削刀具，已经应用了作为提高切削刀具耐磨性和硬度的热处理方法的低温工艺。在这项实验研究中，研究了进给力、表面粗糙度、振动、刀具磨损、硬度和磨料磨损值，这些值是通过低温处理和未经处理的刀具铣削 Inconel 718 材料而产生的。在恒定切深 (0.2 mm) 下，三种不同的切削速度 (35-45-55 m/min) 和三种不同的进给速率 (0.02-0.03-0.04 mm/齿) 被用作实验中的切削参数。作为实验的结果，低温处理刀具获得了较低的进给力、表面粗糙度、振动和刀具磨损。随着进给速度和切削速度的增加，可以看出表面粗糙度、振动和进给力值增加。在实验结束时，确定振动与表面粗糙度之间存在显着关系。然而，磨料磨损和硬度值之间出现了反比。虽然在低温处理的刀具中没有发生 BUE，但观察到在未经低温处理的刀具中发生了 BUE。分别借助二阶方程对振动、表面粗糙度和进给力值获得的 99.14%、99.76% 和 97.98% 的R ²值进行统计建模。
