چکیده مقاله
Today, with increasing concerns about the harmful effects ofthe cutting fluids on the environment, many efforts have beenmade to reduce the consumption of these fluids Oneproposed solution to reduce cutting fluid consumption inmachining processes is using the Minimum Quantity ofLubrication MQL method This method improvesmachining conditions by atomizing the cutting fluid andspraying it on the tool surface In this research the effect ofthe MQL and the machining parameters, including cuttingfluid’s flow rate, MQL nozzle’s air pressure, feed rate, andcutting speed on workpiece surface roughness in the turningprocess of aluminum alloy 7075, were investigated byemploying the Response Surface Method RSM Based onthe results of experimental tests, the lowest surface roughnessobtained using parameters of the fluid flow rate of 275 ml/h,the pressure of 3 bar, cutting speed of 200 m/min, and feedrate of 0 08 mm/rev was measured as 0 438 microns Evaluating the results showed that the feed rate has a directrelationship with the surface roughness, and as the feed rateincreases, the surface roughness also increases The effect ofcutting fluid’s flow rate, air pressure, and cutting speed on theworkpiece surface roughness does not have a consistent trendand depends on the cutting parameters Therefore, statisticalor experimental analysis methods can be utilized to achievethe optimal values of workpiece surface roughness
