Abstract

Hot machining as one of the clean production techniques is used to improve the machinability of hard-to-cut materials. In this technique, an external heat source is used to soften the workpiece material and improves its machinability and sustainability by reducing the machining forces and eliminating cutting fluid application. In the present work, the conventional and hot turning of precipitation-hardened AISI630 stainless steel was evaluated in both numerical and experimental methods. Turning experiments were carried out using PVD-(Ti, Al)N/(Al, Cr)2O3-coated carbide tools, and the flank wear was measured by using scanning electron microscopy (SEM). Numerical analysis was carried out by finite elements method (FEM) to calculate the cutting tool temperature, cutting force values, and cutting force fluctuation. The numerical results showed that the hot turning not only decreases the cutting force but also decreases the amplitude of cutting force fluctuations up to 47%. The experimental results showed that hot turning at 300 °C reduces the tool’s flank wear and machined surface roughness up to 33% and 23%, respectively. Therefore, hot machining could be one of the realistic alternatives that can rise the machining processes on a sustainable level.
