Abstract

Nowadays, Cryogenic Machining has received a lot of attention due to the increasing demand for environmentally friendly production processes. Many studies show that the use of Cryogenic Machining using Liquid Nitrogen (LN2) leads to an increase in tool life, improved shear speed, and material extraction rate compared to other conventional cooling methods such as shear fluid and MQL. In this research, the effect of Cryogenic Machining is investigated on the Roughness and Hardness of AISI 440C Stainless Steel. The results showed that using Cryogenic Machining, the surface Roughness of AISI 440C Stainless Steel was significantly reduced even at a high feed rate. The morphology of the chips showed that with the use of Cryogenic Machining, the surface burn and the accumulation of materials on the inner surface of the chips have been significantly reduced. In this study, it was found that in Cryogenic Machining, the Tool Wear pattern is the erosion pit on the chip surface and has increased the tool life by 400% compared to the dry machining.
