PERFORMANCE OF BLEND VEGETABLE BASED CUTTING FLUIDS INCLUDING EXTREME PRESSURE IN TURNING OF AISI304 STEELS

Abstract

In this study, performances of two different blend vegetable-based cutting fluids (BCFs) including 8 and 12% of extreme pressure additives formulated from sunflower and canola oils, and one commercial cutting fluid (mineral) were investigated for surface Roughness (R-a), turning forces (F-c and F-f) and tool wear (VC and VB). The experiments were realized by turning of AISI 304 austenitic stainless steel with carbide insert tool. Spindle speed, feed rate and depth of cut were considered as machining parameters. Flank wear was taken between 0.2-0.6 mm. Experimental results generally revealed that vegetable based cutting fluids resulted better performances than mineral based commercial cutting fluids considering parameters of lower force, tool wear and surface roughness.
