Abstract

This study investigates the influence of the Minimum Quantity Lubrication (MQL) technique and spindle speed on the surface roughness of AISI 1020 steel during turning operations. recycled cooking oil was utilized as an environmentally friendly MQL lubricant, offering potential as a substitute for conventional mineral oils. In this experiment, two independent variables were considered: the lubrication condition (MQL and dry cutting) and spindle speed, which was tested at three levels (630 rpm, 800 rpm, and 1000 rpm). The dependent variable was surface roughness. MQL was selected due to its ability to enhance cooling and lubrication efficiency while minimizing environmental impacts. Experimental results indicated that at a spindle speed of 1000 rpm, surface roughness achieved 2,221 µm with MQL, compared to 2,824 µm without MQL. These findings highlight that recycled cooking oil-based MQL significantly improves the surface finish and demonstrate that the proper combination of lubrication parameters and spindle speed enhances machining quality. Moreover, this research supports sustainable manufacturing by promoting the use of Recycled Cooking Oil as a green lubricant alternative.

Abstract

This study aims to determine the effect of spindle speed and air pressure on surface roughness and tool wear in the turning process of S45C steel using the Minimum Quantity Lubrication (MQL) system with used cooking oil as an environmentally friendly alternative cutting fluid. The spindle speed was varied at 800, 1000, and 1200 rpm, while the air pressure was set at 1, 2, and 3 bar. The experiments were carried out on a conventional lathe machine with controlled variables including the S45C workpiece material, a feed rate of 0.017 mm/rev, a depth of cut of 0.5 mm, and the use of a carbide insert tool. The dependent variables observed were surface roughness and tool wear. The results show that the application of the MQL system significantly reduced surface roughness and slowed down tool wear compared to dry cutting. The lowest surface roughness value was obtained at a spindle speed of 800 rpm and an air pressure of 2 bar under MQL conditions, while the highest tool wear occurred at 800 rpm and 1 bar without MQL. An air pressure of 2 bar provided the best balance between lubrication and cooling effects, maintaining the stability of the lubricant in the cutting zone. The combination of MQL at 2 bar air pressure and 800 rpm spindle speed proved effective in producing a smoother surface finish, extending tool life, and supporting green manufacturing practices through the utilization of used cooking oil as an eco-friendly alternative cutting fluid.
