Machining and Heat Generation, Pros and Cons: A Review

Abstract

Machining is an important component in the manufacturing sector especially for hard materials at higher parameters level as it enables the fabrication of complex components. These processes are accompanied by the generation of heat, and though this has positive effects on the workpiece it also has negative impacts on it. This review paper goes into the phenomena of heat generation during machining and its ramifications in the manufacturing business. It investigates the factors that lead to heat generation in depth, including plastic deformation, friction, cutting pressures, and tool wear. The paper discusses the benefits of heat generation, such as enhanced plastic deformation and surface finish, as well as the drawbacks, such as thermal damage and tool wear. The need for additional cooling method research (as some have been discovered to be dangerous to humans causing several health as well as environmental issues), the study of new tool materials and coatings, breakthroughs in modeling and simulation techniques, a partnership between academia and industry, and promotion of sustainable machining practices are among the key recommendations. As the knowledge of heat generation during machining is critical, this review paper is an essential resource for researchers, engineers, and manufacturers looking to optimize machining operations and ensure high-quality product manufacturing while taking heat generation into account.
