EFFECT OF CUTTING SPEED ON THE PVD-COATED CARBIDE INSERT IN THE MACHINING ON WASPALOY

Yahya ISIK

Abstract: Waspaloy is a difficult-to-cut material used for gas and steam turbines and aircraft engine components construction that call for considerable strength and corrosion resistance at high operating temperatures. The machining of waspaloy generates high temperatures at the cutting tool edge. The high temperature resulting in the cutting zone critically affects the dimensional accuracy of the job and tool-life of the cutting tool. In this study, the effect of cutting speed on temperature was investigated on tool life and surface quality in the machining on Waspaloy. Experiments were conducted on Waspaloy AMS5708 superalloy samples and a PVD TiAlN-TiN-coated WNVG 080404-IC907 carbide insert was used during the turning process. The highest cutting speed generated higher temperatures. It was concluded that cutting speed the most influencing parameters on chip tool interface temperature and tool life
