Effect of processing parameters on surface integrity

Abstract

In this study, the surface roughness of PMD 23 cold work tool steel in milling with multilayer TiAlN coated cutting tools was experimentally investigated. The effect of surface roughness on the rotation, feed ratio, and MQL flow rate was investigated. The Taguchi technique was used to optimize the milling process. Also, variance analysis (ANOVA) was used to determine the effect of each parameter on the obtained results. Finally, the relationship between dependent variables and independent variables was modeled by regression analysis. In this study, the optimal machinability of PMD 23 cold work tool steel with multi-layer TiAlN coating was determined.
