A Review on Optimization of Hot Machining Process

One of the main goals of the metal-mechanical industries is the reduction of the production costs through the productivity increase. In the attempt to reach this goals, many researchers have been used the hot machining method. This method consists, basically, in the heating of the work piece hundreds of degrees Celsius above room temperature with aid of an external source of heat. Thus, the reduction of the shear stress of the material of the piece is gotten and, hence, is possible to obtain a smaller wear of cutting tool in relation to the conventional machining. This paper presents a review of hot machining, where the different techniques are presented together their results. This review paper presents a survey on variation in process parameter i.e. temperature, cutting speed, feed etc. and their effect on surface roughness, hardness, material removal rate, tool wear, tool life.
