Machining of Carbon Steel under Aqueous Environment: Investigations into Some Performance Measures

In this study, a new machining approach (aqueous machining) is applied for mill and its performance compared with traditional wet machining. AISI 1020 steel employed as the test material Taguchi statistical methodology implemented to analyze compare of two approaches. The cutting speed, feed rate, depth cut were parameters used both types machining, while selected response variables surface roughness hardness. Temperature variations also recorded in aqueous Compared resulted lower (up 13%) same operating conditions about 14% 16% enhancement hardness due formation finer pearlite, revealed by microstructure analysis. parent unmachined surface, machined surfaces was 24% 31% higher 44% 51% Another benefit energy gain, which ranged from 718 8615.96 J. This amount heat can be waste preheating domestic hot water, running organic Rankine cycle inlet saline water desalination, vacuum etc. If successfully future, idea will provide step towards achieving sustainable saving lubricants toxic wastes addition secondary applications.
