Abstract

In this paper, the results of experimental work in dry and high speed turning of AISI 304 austenitic stainless steels using multilayer TiN/TiAlN coated cemented carbide insert are presented. The coating was deposited on fine-grained K-grade (K-20) cemented carbide cutting insert using Cathodic Arc Evaporation (PVD) technique. Micro-hardness of TiN/TiAlN coating was found to be 34 GPa for the thickness of 3.8 μm.  The turning tests were conducted for cutting speeds in the range of 100 to 340 m/min, feed in the range of 0.08 to 0.20 mm/rev keeping depth of cut constant at 1 mm.  The influences of cutting speed, feed and tool coating were investigated on the cutting force and average chip-tool interface temperature. The interface temperature 938°C was observed at 180 m/min cutting speed and 0.16 mm/rev feed. Cutting speed was found to be the dominant parameter for the chip-tool interface temperature whereas feed is the dominant parameter for cutting force. Built-up edge was not observed during turning. Cutting force was found decreasing with the increase in cutting speed.
