“…A decreased contact length results in a decreased chip thickness and accordingly in a decreased deformation of the chip, which in return decreases the chip breakability. According to Balaji et al as well as Friedman and Lenz, a higher thermal conductivity of the work material increases the contact length and thus chip breakability [16,17].…”

Developing improved coated cutting tools to achieve a better cutting performance is one of the key factors in enhancing machining productivity. The present article contributes to the development of electrostatic solid lubricant coating technology to produce high-performance coated tools for machining process improvement. Machining tests and finite element analysis were performed to evaluate the proposed novel coating technique. The results obtained from the experiments and simulations demonstrate the effectiveness of the presented technology in reducing the generated heat during machining as well as enhancing wear characteristics of the tool. The results also prove that the developed solid lubricant coating technique will play an important role in sustainable machining.

“…Heat generated during machining causes two changes in the cutting tool; reduces mechanical and wear resistance [4]. It is proven that the deformation and friction converts 99% input energy to heat [9]. This leads to the tool wear subsequently which reduces the tool's life span [2].…”

Abstract. The usage of cutting fluid in the machining operations will not only poses health risk to the workers but also creates environmental challenges associated with fluid treatment and disposal. The objective of this review paper is to identify present cooling method in dry machining and novel feature than can be included in the cooling system for a better heat removal which tend to increase machining performance. From the review study, it shows that cooling method by internal manner is most widely been researched because researcher believes that it has a promising future in adaptive machining to produce a contamination free products which supports the green manufacturing concept. The suggested novel feature is ecologically desirable and it will become as a necessity for improving the performance of dry machining in the near future.
