The Effectiveness of Hot machining process for the Machinability of Hard to cut materials: A REVIEW

In the manufacturing field of industrial firms, some materials are hard to cut and do not meet the mechanical operation requirements in conventional and unconventional machining methods due to their high mechanical properties which poorer their machinability. The need is ongoing and growing to these materials in important industries, therefore hot machining is considered one of the most advanced methods of machining which help to solve the problem of these materials. This process involves heating the work piece at elevated temperature during or before machining on conventional cutting machine by using various external heating techniques, which soften it and becomes more ductile and this leads to improve the machinability. This paper displays a review on hot machining process and presents its effectiveness for the industrial firm in machining hard-to cut-materials which reflect on cost and productivity in relation to other aspects of machining. The review paper presents a survey on various researches which indicates the effect of variation process parameters in hot machining.
