Pengaruh jenis proses pemotongan pada mesin milling terhadap getaran dan kekasaran permukaan dengan material aluminium 6061

Abstract

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 μm and 1,03 m/s², profile milling of 1,0984 μm and 1,49 m/s², pocket milling of 1,1004 μm and 1,73 m/s², slot milling of 1,4888 μm and 2,44 m/s² and drilling of 1,9944 μm and 18,62 m/s². 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.
