Abstract : Hot-machining tests in turning, boring, and milling were conducted on AISI 4340, AISI 4150, and on manganese steel workpieces to improve the shaping of both conventional and difficult-to-machine alloys. The workpieces were heated during the machining operations by one of three methods, namely a sliding electrode, a TIG torch, and friction elements. Test tool materials were of various types of ceramics, tungsten-titanium carbides, titanium carbides, and titanium-coated carbides. Cutting force measurements were made with a three-component dynamometer. (Modified author abstract)
