【 摘 要 】

Machining with tool that have cutting edge radius provides components with high fatigue strength, microhardness of a largesurface layer and plastic deformation. Finite element simulations of the cutting process give a better knowledge of the chip generationphenomenon, heat generation in the machining area, stress and temperature field results. This study emphasizes the true importanceof the mathematical model that underlies the shape of the tool in the pre-processing steps of finite element analysis. The argumentis that its achievement and definition depend on the network difficulty. This research purpose is to perform simulations series oforthogonal machining with different radius and depth of cut. In this way, conclusions on the impact of these variations on the wholecutting process were drawn. The finite element application used is Deform 2D, the Lagrange incremental method and the JohnsonCook material model. The temperature distribution, stress distribution, von Mises stress distribution, effects on specific tool pressureand wear, and fluctuations in the cutting resistance of the tool tip and C45 workpiece were analyzed.
