Abstract
Several attempts to find sustainable manufacturing methods led us to study the performance of vegetable-based oils as cutting fluids in machining processes. Vegetable-based oils, despite having lower lubricating potential compared to mineral oils, tend to be less harmful to the operator's health and are more biodegradable. The roughness generated by the tool during chip removal significantly affects friction properties, surface wear, heat transmission, mechanical strength, fatigue, and fluid transport. Specifically, for parts with strict dimensional tolerances, these properties are closely linked to their performance in service. Cutting speed, feed rate, depth of cut, cutting forces, workpiece material characteristics, and tool properties directly affect the resulting surface integrity of the produced part. Thus, the aim of this study is to investigate the performance of sunflower-based vegetable oil applied as Minimum Quantity Lubrication (MQL) during face milling of ABNT 1045 steel in terms of roughness. The results obtained were compared with the performance of the commercial lubricant LB 2000, also applied in MQL form. It is concluded that at a flow rate of 50 ml/h, the machining parameters, in combination with the fluid used, determine the surface roughness of the workpiece. Neither of the oils proved to be more efficient with all the tested cutting parameters.
