In this work, the manufacturing steel has been machined on a CNC lathe without cutting fluid, at various cutting speed, feed rate and depth of cut. Effect of cutting speed, feed rate and depth of cut on surface rougness were investigated by machining the manufacturing steel by a carbide insert without coating. In the experiments three different feed rate values between 0.1, 0.2, 0.3 mm/dev, three different depth of cut 1, 1.5, 2 mm and three different cutting speed 100, 180, 280 m/min were used and the manufacturing steel (st1050) that is known mechanics and chemical properties was processed. In this experiment, total 27 specimens were turned. Surface roughnesses that was found were measured and wearing rate of cutting tools was investigated. In this way, Surface roughnesses and optimum cutting parameters for the manufacturing steel was determined. In this work, optimum cutting parameters and minimum surface roughnesses were tried to determine for selected material and cutting tip. © 2017, ModTech Publishing House.
