Evaluating machining performance of AlSI 1014 steel using gingelly oil as cutting fluid

ABSTRACT

Cutting fluids are generally used for lubrication and cooling the machined surface during the turning operation. The petroleum-based oil, when used for the machining process, has raised many health and environmental issues. The use of bio oils during machining process results in environmental-friendly working atmosphere, with minimal health hazardous among workers. Many researchers have worked on the effect of process parameters, surface characteristics of the machined surface by using bio oils as lubricants. The metallurgical transformation takes place on the machined surface during the machined surface. But the studies on using the bio oils on improving the machined surface, chip formation and generation of cutting force needs to be studied in details with comparison with other process methods. The change in the microstructure, during the machined process also needs to be studied thoroughly, where mere literatures are available.

With this direction, the experimental studies were conducted to study the machining parameters during the turning process by using gingelly oil as cutting fluids. The studies showed that there was a gradual decrease in cutting force and improved surface finish on the machined part. The improvement in the machinability during the cutting process with respect to chip length, pitch and surface roughness was discussed for all the process. Finally, the changes in the microstructure on the metal surface for the different cutting forces were studied.
