Abstract :

This article exposed the results of an experimental study on the machining of steel annealing 42CRMO4 with Brinell hardness HB 174, with two cutters: White zirconia ceramic (Al2O3 and ZrO2 ) and the carbide (made of tungsten carbide WC). The test series is devoted to the study of the influence of cutting conditions on the main criteria of the roughness of machined surfaces (Ra, Rz and Rt). For this, we have made plain factorial trials and based on multifactorial method of experimental design, the variable parameters: Cutting speed, feed per revolution and the depth of cut were designed. Modeling results helped in leading mathematical models like Gilbert (Taylor model generalized). Machining of the steel pure ceramic gave very good surface states with high cutting speeds.
