Abstract
In this research, effect of physical vapor deposition–coated (TiAlN–TiN) carbide inserts with various edge preparations (cutting edge radius) and rake angles on cutting forces and temperature is studied at different cutting parameters for the interrupted machining of Ti6Al4V. It is noted that with the increase of edge radius, cutting and feed forces as well as temperature increase, and the effect on the feed force is more significant. Similarly, forces and temperature are measured for three different rake angles at two different feed rates keeping all other parameters constant. Forces and temperature show a decreasing trend with increasing rake angle. A comparison of the machining performance of Ti5553 and Ti6Al4V is also presented. Ti5553 alloy shows higher temperature as compared with Ti6Al4V at all cutting parameters because of its high hardness and strength attained due to the higher concentration of β stabilizers (Mo and V). Results of this research would be helpful for the tool manufacturers in designing novel geometries for coated cutting tools, used to machine wide range of α/β and β titanium alloys.This publication has 13 references indexed in Scilit:
