Dry cutting: A sustainable machining technology

Conventional cutting fluids with flood cooling are used to reduce the heat generation during machining but at the cost of environmental degradation. The hydrocarbon-based conventional cutting fluids are harmful to the operator’s health, environmentally unfriendly, and problematic to disposal and recycling. The possible solution being explored is machining without cutting fluid or lubricant. Dry cutting has been investigated for many years to overcome the machining challenges. However, tool wear still remains a problem in dry cutting. Dry cutting at optimum parameters and using coated and treated tools can be the possible solutions. This chapter sheds light on dry cutting of various engineering materials via some case studies. The chapter aims to facilitate researchers working on green or sustainable machining and to encourage them to establish the field further. © 2021 Elsevier Inc. All rights reserved
