Abstract:

In this study, orthogonal turning experiments are performed to analyze the machinability of Ti-5Al-2Sn-2Zr-4Mo-4Cr (Ti-17), a β-rich, α+β type alloy. PVD TiAlN coated carbide tool inserts are applied, because they are used widely for machining this material. The cutting forces and cutting temperatures are examined under different cutting conditions, which the cutting speeds are varied from 44m/min to 123m/min, the feed rates are 0.06mm/r, 0.08mm/r, 0.10mm/r and 0.12mm/r,respectively.There are some different varying trends of both the cutting force and the thrust force with the change of cutting speed. The cutting temperatures are found to increase with cutting speeds as well as feed rates.
