In turning processes, the use of cutting fluids is the most common with mineral oil-based cutting fluids flooded to the tool-chip interface. This method bring the environmental, health and cost concerns according to Material Safety Data Sheet. Minimum quantity lubrication (MQL) and the use of vegetable oil-based lubricants have become the focus of attention as the alternative to traditional fluids. This research starts with turning the workpiece in MQL condition using vegetable oil to observe the effects of the response. Then the experiments is designed with tool nose radius, cutting speed, feed rate, and depth of cut as parameters and material removal rate (MRR) and surface roughness (Ra) as response that will be measured. The data from the experiments then will be modeled as multiple regression model so the relationship between parameters and responses can be determined. The model then will be tested statistically to find the significance of each parameters to the response. The effects of using vegetable oil in MQL condition then will be analyzed by comparing the data from this research with another research that use dry machining as cutting condition. Optimum values are then selected by observing which combination of parameters that produces the best outcome of MRR and Ra. This research proves that the use of vegetable oils in MQL condition will improve the surface roughness in turning process.
