Different Aspects of Machinability in Turning of AISI 304 Stainless Steel: A Sustainable Approach with MQL Technology

Machining of AISI 304 austenitic stainless steel is considered to be difficult due its structural aspects and low thermal conductivity, which leads increased temperatures during machining. To overcome the challenges machining steel, several cooling lubricating techniques have been developed. The main objective this experimental study evaluate different turning conditions AISI304 under dry minimum quantity lubrication (MQL) environment conditions. experiments were conducted using a two-level full factorial design method utilized TiC-coated cutting tool. tool-tip temperature, force surface roughness analyzed regarding three parameters namely, speed, feed rate depth. Also, chip macro-morphology was investigated define interaction at tool-chip-workpiece region. medium affects significantly (more than 100%) for all parameter values. In some environmental conditions, high speed provides 10% lesser parameters. decreases by 20% in However, effect disappeared forces rates depth both MQL environments. Cutting observed as most influential factor on roughness, followed rate. cut that caused temperature increase environment.
