Study of machining parameters while turning austenitic stainless steel AISI304

Author(s): Rajendra S Ghatode, Mahindra N Pande, Jeevan R Gaikwad
Abstract: Stainless steels are hard materials and difficult to machine as seen in research work done until now. A machining industry which aims for higher quality and higher productivity at low cost, will definitely face problem with elevated temperatures at the metal cutting zone during the machining process, as the conventional cooling methods fail to reduce the heat at tool –chip interface thereby affecting the performance. This problem can be handled largely by reducing the cutting temperature. Hence, a cryogenic coolant is highly recommended for this purpose. Based on the results obtained from the experimental work done until now, it can be concluded that machining with the cryogenic CO2 cooling had a substantial benefit with respect to the cutting temperature, cutting forces, chip thickness and morphology, surface roughness, shear angle, and tool wear, when compared with the other conventional cooling methods. In this project, works on the various machining parameters affecting the effectiveness of turning AISI 304 are reviewed for improving surface finish. Process parameters such as cutting speed, feed rate, depth of cut mainly under conventional cooling and cryogenic cooling conditions are considered. Cryogenic cooling setup for supplying CO2 gas was developed. The work material Austenitic stainless steel AISI 304 is selected for performing various experimentations. The result is further confirmed by experiments. Finally output parameters like surface finish can be optimized for economical production.
