A Study direction milling affecting surface roughness by the Taguchi method with a 10 mm. bite milling cutter, the direction of milling is clockwise, G41 and counter clockwise milling. G42 is intended to measure the milling direction of the workpiece by testing with brass and aluminum materials. By measuring the milling direction, the feed rate is 100 mm / min, the speed is 1500 rpm and the depth of milling is 3 mm. The clockwise and counterclockwise hands provide better surface roughness and, from the test, the factors that affect the roughness of the surface are brass and aluminum. The coefficient of variation in surface roughness of the test specimens was 4 factors, namely, feed rate of 80, 100 and 120 mm/min, speed of 1200, 1500 and 1800 rpm. The 3, 4 and 5 mm workpieces are machined and the milling direction is divided into two parts: G41 clockwise bite counterclockwise G42 brass and brass material testing. It is found that the correct direction for brass milling is the direction of machining G41, with a cutting speed of 1200 rpm. The feed rate is 120 mm/min. And the depth of bite is 4 mm. The surface roughness of the workpiece is minimal. The surface roughness is 0.84 ?m. The optimum direction for aluminum milling is G42 cutting direction. The cutting speed is 1200 m/min. The feed rate is 120 mm/min. And the depth of biting is 5 mm. The surface roughness of the workpiece is minimal. The surface roughness was 0.75 ?m.
