In this research, we had studied the sensitivity for machining of cobalt-based superalloy Haynes 188 with ceramic cutting tool. The investigation had focused on the effects of the cutting speed, on the cutting forces, and on the surface roughness based on Taguchi’s experimental design. The effects of machining parameters were determined using Taguchi’s L27 orthogonal array. The signal-to-noise ratio was calculated for the average of surface roughness and the cutting forces, and the smaller were used to determine the optimal cutting conditions. The analysis of variance and the signal-to-noise ratio had effects on the parameters on both surface roughness and cutting. Three different types of cutting tools had been used in the experiment, namely KYON 4300, KYS 25, and KYS 30. The cutting force of Fz was considered to be the main cutting force. Depending on the material which had been used as cutting tool, the Fz had the lowest cutting speed and the lowest surface roughness with the KYS25 ceramic tool. The cutting force and the surface roughness of KYON 4300 cutting tool had shown better performance than other cutting tools. The flank wear and notch were found to be more effective in the experiments. The long chips were removed at low and medium cutting speeds, while the sawdust with one edge and narrow pitch at high cutting speeds was obtained.

在这项研究中，我们研究了陶瓷刀具加工钴基高温合金 Haynes 188 的敏感性。基于田口的实验设计，研究的重点是切削速度、切削力和表面粗糙度的影响。使用田口的 L27 正交阵列确定加工参数的影响。计算表面粗糙度和切削力的平均值的信噪比，并使用较小的值来确定最佳切削条件。方差分析和信噪比对表面粗糙度和切削参数都有影响。实验中使用了三种不同类型的刀具，即 KYON 4300、KYS 25 和 KYS 30。Fz 的切削力被认为是主要的切削力。根据用作切削刀具的材料，使用 KYS25 陶瓷刀具时，Fz 具有最低的切削速度和最低的表面粗糙度。KYON 4300刀具的切削力和表面粗糙度均表现出优于其他刀具的性能。在实验中发现后刀面磨损和缺口更有效。长切屑在低、中切削速度下被去除，而在高切削速度下得到单刃和窄节距的锯末。在实验中发现后刀面磨损和缺口更有效。长切屑在低、中切削速度下被去除，而在高切削速度下得到单刃和窄节距的锯末。在实验中发现后刀面磨损和缺口更有效。长切屑在低、中切削速度下被去除，而在高切削速度下得到单刃和窄节距的锯末。
