Assessment of Chip Morphology, Cutting Forces and Tool Wear in Precision Turning Process of Ti-6al-4v Alloy

摘要

This research work focuses on precision machining of Ti6Al4V material. The cutting parameters considered for the experiments include the cutting speed, feed rate depth of cut and nose radius. PVD coated carbide cutting inserts with different nose radius and constant rake and clearance angle are being considered for experimentation. The experimentation will be designed based on Taguchi's L 27 orthogonal array. Three different levels of cutting parameters are being considered for the experimentation. The knowledge of cutting forces developing in the various machining processes under given cutting factors is of great importance, being a dominating criterion of material machinability. Chip morphology and segmentation play a predominant role in determining machinability and tool wear during the machining of titanium alloys. Based upon the experimental values, will be conducted to understand the influence of various cutting parameters on cutting force, tool wear and chip morphology during precision turning of titanium alloy. Further experiments will be conducted to understand the trend of variation in each measurable parameter for the variation in every cutting parameter. As a result the machinability of the said material could be understood which will provide a good understanding for the users of the material in different applications.
