Purpose -The purpose of this paper is to investigate the performance of four cutting oils, two different vegetable-based cutting fluids developed from refined sunflower oil and two commercial types (semi-synthetic and mineral), for surface roughness during drilling of AISI 304 austenitic stainless steel with HSSE tool. Design/methodology/approach -L 9 (3 3 ) orthogonal array was used for the experiment plan. Spindle speed, feed rate and drilling depth were considered as machining parameters. Findings -Results were evaluated statistically. Mathematical models based on cutting parameters were obtained from regression analyses to predict surface roughness. ANOVA was used to determine the effect of the cutting parameters on the surface roughness. The performance results were found to be better for vegetable-based cutting oils than that of commercial ones. Originality/value -The paper reports on the use of refined sunflower oil in drilling stainless steel.

This study focuses on both formulation of vegetable-based cutting fluids (VBCFs) and machining with these cutting fluids. For this purpose, characterizations of chemical and physical analyses of these formulated cutting fluids are carried out. In this study, performances of three VBCFs developed from crude sunflower oil, refined sunflower oil, refined canola oil and commercial semi-synthetic cutting fluid are compared in terms of tool wear, thrust force and surface roughness during drilling of AISI 304 austenitic stainless steel with HSSE tool. Experimental results show that canolabased cutting fluid gives the best performance due to its higher lubricant properties with respect to other cutting fluids at the constant cutting conditions (spindle speed of 750 rpm and feed rate of 0.1 mm/rev).
