In the machining process, the friction between the tool and the surface being machined, in addition to the destructive effects on tool wear and surface quality, increases the cutting force. By applying lubricant, it is possible to reduce the friction force in the machining process, and as a result, the cutting force is reduced. Due to the harmful environmental effects of excessive use of lubricants, the method of minimum quantity lubricant (MQL) can be helpful. In this method, fluid is applied with controlled flow and pressure. In this research, the effect of machining conditions on the cutting force for the machining process of AISI 304 stainless steel, using the method of minimum quantity lubricant has been investigated. The results show that with the increase in the cutting speed, the cutting force has decreased. Also, with the increase of injection pressure when applying the lubricating fluid using the method of the minimum quantity lubricant, a significant increase in the cutting force has been observed.
