This research was aims to determine the effect of the cutting process type on a milling machine to vibration and surface roughness of the aluminum 6061. The specimens were made using a cutting process type face milling, profile milling, pocket milling, slot milling and drilling. Surface roughness data retrieval is done on any type of cutting process using a surface roughness tester and vibration data was taken during a cutting process on any cutting process type using a vibration meter. The results showed the value of surface roughness and vibration in face milling of 0,5368 Î¼m and 1,03 m/sÂ², profile milling of 1,0984 Î¼m and 1,49 m/sÂ², pocket milling of 1,1004 Î¼m and 1,73 m/sÂ², slot milling of 1,4888 Î¼m and 2,44 m/sÂ² and drilling of 1,9944 Î¼m and 18,62 m/sÂ². Cutting process type on a milling machine having an influence on the vibrations and surface roughness. Each cutting process type has a different cutting force. The greater the cutting force that occurs in every cutting process type, the greater the value of the vibration and the surface roughness happened.

This research was conducted to find out the influence of the implementationof CAD/CAM for CNC milling process to the surface roughness andprecision. Specimens were made by using seven types of cutting process.There are face milling, pocket milling, profile milling, slot milling, drilling,thread milling, and surface contouring. The results showed that theimplementation of CAD/CAM with a variation of the cutting processproduces roughness value which is lower than without the implementation ofCAD/CAM. The surface roughness values for each of the cutting processwere face milling process (0.5028 Î¼m; 0.5132 Î¼m), slot milling (0.664 Î¼m;0.6556 Î¼m), profile milling (1.282 Î¼m; 1.3128 Î¼m), pocket milling (1.3852Î¼m; 1.4856 Î¼m) and drilling process (1.9944 Î¼m; 2.1136 Î¼m). The averagevalue of the dimensions from the measurement showed the differencebetween the results of the implementation of CAD/CAM and without theimplementation of CAD/CAM. The percentage difference in the length andwidth were respectively 0.037%; 0.059% for profile milling; 0.039%;0.061% for pocket milling; and 0.151%; 0.317% for drilling. Statistical useof the implementation of CAD/CAM does not significantly affect the value ofthe surface roughness but it has a significant influence on the precision ofthe product with a 95% precision level.
