The cutting tool edge preparation is considered as one of the important technologies that were recently developed micro-machining due to its impact on cutting forces and stresses, tool life, temperature distribution and surface integrity and precise tool-edge geometrical measurements. The most frequent tool edge preparation include round edge, chamfered edge and sharp edge. It is not easy to determine, for a given workpiece material, the appropriate tool edge preparation or the machining parameters that should be used, as they might affect several machining performance indicators. The objective of this thesis is to conduct a research study on the effects of three cutting tool edge geometries and the cutting parameters on the machining characteristics such as cutting temperature, effective stress, chip thickness and tool wear. The cutting tool edge geometries were round, chamfer and sharp. This study consisted of simulating numerically the orthogonal cutting process of AISI 1045 steel using 2D finite elements DEFORM software
