Sažetak
This paper presents an analysis of stresses value and tool displacement in the cutting tool during hard end-milling of 42CrMo4 steel. During machining cutting parameters: cutting speed (vc), depth of cut (ae), feed rate per tooth (ft) as well as different machining conditions like dry machining, conventional emulsion cooling and cooling by cold compressed air were varied. Numerical simulations by the Ansys Workbench 17.1 software were used to study the influence of machining parameters in different machining conditions on stresses distribution and tool displacement. Analysis was based on finite element method (FEM) and all procedure is demonstrated by using experimental observations of cutting forces Fx, Fy and Fz. The results of this study indicated that machining conditions have a significant impact to the cutting forces. The cutting force results are great indicators of stress value and tool displacement where through the finite element analysis (FEA) can to observe their impact on critical areas in the cutting tool. Having knowledge of FEA results is of great importance for selection of optimal cutting parameters and for define optimal conditions during machining. It is concluded that FEA results in the zone of total tool displacement and maximal stress value is relatively matched with the zone of tool wear observed by experimentally.
