- Machining process is one of the cutting or metal forming process often done in the manufacturing industry, a product by means of a chisel (cutter) spins and each tooth or slicing by cutting. In this process there is the effect of surface roughness value as a result of the slicing. Surface roughness is one of the parameters to determine the specification of good or not a product. Factors that are. Affecting surface roughness are: cutting speed, feeding motion, cutting depth. In this research will analyze the effect of cutting parameters on surface roughness inprocess side milling. To analyze the surface roughness at this test was done 16 times testing with machining condition based on CCD (Central Composite Design) with three cutting parameters namely cutting speed, feeding motion, cutting depth. The workpiece used is a low carbon steel with dimensions of 25 mm x 95 mm x 95 mm by doing machining side milling on the side of the workpiece. Where side milling is cutting by using side cut side (side) from cutting tool. Scaling is done with as many as 16 times with different parameters according to table 3.4 test parameters with a constant radial feeding thickness of 0.5 mm. In the process of machining the cutting fluid used is sunflower oil by the method of use discharged in the active cutting field. Based on the data analysis obtained from the testing process it is known that the correlation of the cutting speed to the surface roughness value is the larger the cutting speed, the smaller the resulting surface roughness, whereas the relation of feeding and the cutting depth to the surface roughness value is the greater the value of feeding motion and the depth of cutting the greater the resulting surface roughness. The highest surface roughness values in this study were in the test variables with Vc = 9.6 m/min, fz = 0.1 mm/tooth, and aaxial = 8 mm of 1.51 μm. While the lowest surface roughness value was studied in the test variables with Vc = 9.6 m/min, fz = 0.05 mm/tooth, and aaxial = 4 mm of 0.59 μm.
