Comparative assessment on the machinability of EN 24 and EN 36C steels

Abstract

EN 24 steel is medium carbon steel of nickel-chromium-molybdenum grade generally used for manufacturing heavy-duty axles, shafts, etc., whereas EN 36C steel is low carbon, nickel-chromium case hardened steel used widely in the manufacturing of heavy-duty crane shafts, aeroplane gears, cams, rollers, etc. The paper presents the comparative analysis on machinability of two varieties of steels, i.e. EN24 and EN 36C steels. Machining experiments were done according to 3 3 factorial design. Cutting speed, feed and depth of cut are the input process parameters and chip reduction coefficient, Von Mises stress, temperature differential and tool wear are the output parameters considered in the analysis. Metal removal of the work material was done in a conventional way by using carbide tool and lathe.
