The production time and cost of machine parts decrease while fatigue strength increase in manufacturing of cylindrical parts from hardened steels when hard turning is preferred instead of grinding. X40CrMoV5-1 hot work tool steels are commonly used in manufacturing of injection and extrusion mold, and also in process which require high toughness and wear resistance in high temperature. In this study, the main cutting force (Fc) in machining of X40CrMoV5-1 tool steel hardened to 55±1 HRC in vacuumed heat treatment with uncoated ceramic tools were experimentally measured. The machining experiments were performed according to Taguchi L9 orthogonal array with different cutting parameters (cutting speed, feed rate and depth of cut). Kistler 9257B type of dynamometer and its equipments were used for measuring of cutting forces. The numerical analysis for cutting forces was carried out with DEFORM 3D software which has solutions according to finite element method. Moreover, the effects of cutting parameters on cutting forces has been specified with ANOVA in %95 confidence level. It was determined that average of %94 similarity between experimental and numerical analysis results for cutting forces. It was shown that the most important factor on Fc is depth of cut according to ANOVA results conducted based on experimental data.
