Experimental Determination of Cutting Temperature and Force when Turning Assab Steel with Coated Carbide Inserts

Abstract:

The study is about an experimental investigation of the different factors influencing the temperature occurring at the coating/substrate and chip interface when machining Assab steels 760 and DF2 with two different coated carbide tools. Results show that tool temperature was higher when turning Assab steel 760. Temperature along the major flank face was higher that that at the minor flank. However, the magnitude of temperature was lower than expected with maximum only around 260 oC near the tool tip. The performance of Al2O3 coated WC inserts appeared to be better compared to TiN coated WC inserts. The cutting temperature was lower with alumina coated tools. While turning Assab DF2 steel, cutting temperature was lower compared to Assab 760 steel for the same coated tool.
