Abstract: In this work, an experimental investigation was carried out to establish the influence of surface temperature, cutting speed, feed and depth of cut on cutting forces, surface finish, and tool wear in hot machining. For this purpose, an oxy-acetylene hot machining set-up was designed, fabricated and installed on a lathe machine. Experiments were carried out both in hot machining and conventional machining conditions to determine the relative advantage offered by hot machining. An expression for the effects of cutting conditions, namely, cutting speed, feed and depth of cut on cutting forces, surface roughness, and flank wear was determined using a mathematical model developed by a factorial regression method. Cutting forces, surface roughness and flank wear in hot machining were compared with the conventional machining. It was found from the experimental results that hot machining was effective in bringing down the cutting forces, surface roughness and flank wear by about 34%.
