Abstract |
Titanium and its alloys possesses superior properties such as high strength/weight ratio and corrosion resistance, however machinability of these alloys are considered to be poor. In order to overcome this disadvantage, improvements in machining processes, cutting tool materials and geometries have been carried out. The purpose of this study is to investigate the influence of textured cutting tools on machining performance of Ti6Al4V. For this purpose, a Finite Element Method model is developed regarding the conditions defined in literature and it is validated. Two different texture geometries are modelled through this model. Orthogonal cutting simulation is performed for four different rake angle values. Resulting cutting force, chip length and cutting temperature values are compared with untextured tool results. It is found that that textured geometry with 10 μm groove depth resulted in a 31% reduction in cutting force, while the tool with 95 μm groove depth did not yield a significant difference. The results show that using a textured tool geometry is an effective method for improving machining performance;however, texture geometry and machining parameters should be selected carefully.
