al2o3基陶瓷具有较高的硬度和耐磨性，是加工淬硬钢最合适的刀具材料之一。然而，它们的高度脆性往往导致结果不一致和突然的灾难性破坏。这就需要在使用基于Al2O3的陶瓷刀具加工硬化钢时进行工艺优化。本文概述了采用田口技术实现这一目标的实验研究。采用正交阵列和方差分析（ANOVA）研究了切削速度、进给速度和切削深度3个切削参数对刀面磨损（VB）和表面粗糙度（R-a）两项性能指标的综合影响。得到各性能指标的最优切削参数；并利用多元线性回归确定了各参数与绩效指标之间的关系。(c) 2006 Elsevier Ltd.版权所有。
Due to their high hardness and wear resistance, Al2O3-based ceramics are one of the most suitable cutting tool materials for machining hardened steels. However, their high degree of brittleness usually leads to inconsistent results and sudden catastrophic failures. This necessitates a process optimization when machining hardened steels with Al2O3 based ceramic cutting tools. The present paper outlines an experimental study to achieve this by employing Taguchi techniques. Combined effects of three cutting parameters, namely cutting speed, feed rate and depth of cut on two performance measures, flank wear (VB) and surface roughness (R-a), were investigated employing an orthogonal array and the analysis of variance (ANOVA). Optimal cutting parameters for each performance measure were obtained; also the relationship between the parameters and the performance measures were determined using multiple linear regression.
