本文对Inconel 718在常规和各种高压冷却条件下的可加工性进行了试验研究。实验设计基于田口L18正交阵列，在三种不同的切削速度、进给速率和压力水平以及两种不同的切削深度下进行。用（Ti,Al）N+TiN涂层CNMG0812车削加工Inconel 718时，测量了切削力和刀面磨损。为了确定切削参数对刀面磨损和切削力的重要性，采用方差分析（ANOVA）。通过回归分析，得到了刀面磨损、切削力和切削参数之间关系的多元回归方程。实验结果表明，使用高压冷却液可显著降低刀面磨损和切削力。方差分析结果还表明，高压冷却对刀面磨损有显著的有利影响。
The paper deals with the experimental investigation on machinability of Inconel 718 in conventional and various high pressure cooling conditions. The experiments designed based on Taguchi L18 orthogonal array at three different cutting speed, feed rate and pressure levels and two different depth of cuts. The cutting forces and tool flank wear were measured, while turning of Inconel 718 with (Ti,Al)N+TiN coated CNMG0812. In order to determine the importance of cutting parameters on tool flank wear and cutting forces, ANOVA (Analysis of variance) was employed. Moreover, with regression analysis, multi regression equation which indicating relation between tool flank wear, cutting forces and cutting parameters were obtained. The experiment results have proven that the tool flank wear and cutting forces considerably decrease with the use of high pressure coolant. ANOVA results also indicate that high pressure cooling has significant beneficial effect on tool flank wear.
