Abstract

The quality of production goods usually considered good if it has a good surface roughness component quality. Some various factors that cause surface roughness are cutting speed, cut of depth, and feeding movement. This study will analyze the effect of cutting parameters on surface roughness in the process of side milling. To analyze the surface roughness in this test conducted 16 times of test by machining conditions based on CCD design CCD (Central Composite Design) with three cutting parameters, namely: cutting speed, feeding movement, and cut of depth. The workpiece used is a low carbon steel with dimensions of 100 mm x 100 mm x 20 mm machined side miling process on the side of the workpiece. Side milling is cutting by using side pieces of cutting tool. cutting is done with the number of 16 times with different parameters according to table 3.3 parameter testing, with a constant radial depth of 0.5 mm. In machining cutting fluid process that used is coconut oil with the method of use poured in the active cutting field. Based on data analysis obtained from the testing process, it is known that the relationship between cutting speed toward the value of surface roughness is the optimum condition of cutting occur on Vc condition amounted to 16,33 m/min. Whereas the relationship of feeding movement and cut of depth on the value of surface roughness is the greater the value of feeding movement and cut of depth then the greater the value of surface roughness. The highest value of surface roughness in this study is in the variable test with Vc = 9,58 m/min, Fz = 0,1 mm/flute, and aaxial = 10 mm amounted to 5.17 μm. Whereas the lowest value of surface roughness in this study is in the variable test with Vc = 16,33 m/min, Fz = 0,26 mm/flute, and aaxial = 7,5 mm amounted to 1,64 μm. The result of analysis of surface roughness with mult iple linear regression equation by using SPSS software given the average percentage of difference to Ra test amounted to 16,17 % with the largest percentage difference shown in the third test amounted to 38,35 %. Whereas the smallest percentage difference shown in the fourth test amounted to 0,35 %.
