【 摘 要 】

There is a want for materials of high hardness and resistance for aerospace applications. Metal cutting of the said kind of blends and metals needs special machining inserts that occasionally is not cost-effective and even unfeasible. In addition, even the untraditional methods are commonly limited to the socket of sight of productivity. The growth of built-up brink and bonding coat on the insert rack surface also worsens on one needle, the profile and effectiveness of machining insert and on the other needle, the surface quality and measurement accurateness of the finished product. The usage of coated tool inserts will diminish the development of brink and bonding coat to a considerable extent which in turn improves tool life thereby reducing tool wear. This paper will focus on studying the effect of machining constraints on machinability of Ti6Al4V using carbide cutting inserts with double layer and without coating in metal cutting without coolant and by examining the stress spreading, turned surface finish and insert attire. Nine experiments using uncoated inserts and dual layer coated inserts were conducted by varying the machining speeds and feeds. The machining process was also simulated in AdvantEDGE Workbench to study corresponding stress and strain distribution.
