A105 Work-Material Turning Experimentation using L9 Orthogonal Array Runs with Dry, MQL and Nano-Al2O3 Assisted MQL Machining Conditions

Abstract

A105 carbon structural steel material exhibits high strength and hence pose machining difficulties such as excessive tool wear due to high cutting temperatures. Abrupt cutting actions due to improper selection of feed rates have posed to bad surface finish of work-pieces. These materials find best applications in flanges and pipe fittings and generally turning operations are conventional methods to change its dimensions and attaining accuracy levels. An attempt is made to experiment on A105 work material using lubricant vegetable coconut oil under minimum quantity lubrication ( MQL) assisted by nano-particles such as Al2O3 in order to find suitable combinations of working environments, to compare with dry cutting, and also to decide suitable feed rates and cutting speeds combinations.
