PENGARUH MEDIA PENDINGIN DAN KONDISI PEMOTONGAN LOGAM TERHADAP KEKASARAN PERMUKAAN PADA PROSES MILLING MENGGUNAKAN MESIN CNC TYPE VMC 200
ABSTRACT: There are many
factors influencing the quality of products that are produced from milling machine
process. The quality is mostly dealt with the surface roughness which is not in
accordance with specifications that are required. Those influencing factors are
the selection of cutting patameter regulation, for example, the speed of
milling process and cutting, and selection of the cutting depth. Others factors
are quality of tool life, cooling media and etc. The product quality on surface
roughness can gained by varying the regulation of cutting parameter selection.
The speeds for cutting are 43 m/min, 55 m/min dan 72 m/min, while the feed rate
are 40 mm/min, 60 mm/min and 85 mm/min. The cooling media to be applied is air,
with the ratio of water cooling media is 1:30 and 1:60. The type of machine
used is CNC Type CMC 200 and surface tester devices used to measure roughness
of cutting process result. Of mesasurement result, it can be seen that cooling media
influence the surface roughness very much. The relationship between surface roughness
and cooling media is SRair = 4.207 v-0.69 f0.45 water and cooling media is and SRidemitsu
(1:60) = 1995.2 v-1.38 f-0.46.
