PENGARUH VARIASI KECEPATAN DAN VARIABEL PUTARAN SPINDEL MESIN FRAIS TERHADAP KEKASARAN PERMUKAAN PADA PROSES FRAIS MMC MATRIKS KUNINGAN PENGUAT FLY ASH
ABSTRACT: Metal matrix
composite (MMC) is composite material which based bronze as matrix material and
fly ash as strenghtener material. Fly ash is one of product
of sugar industry burning
retention. MMC consist of 15% wight of
Cu, 83% wight of Zn, and 5% wight of flay ash. This researche will explore
machinabilities of this material. Milling machine metode is choised for cutting
of this material. Problem of this research are:" What are feeding (s) and
revolution of spindle (n) influence to surface roughness as cutting product of
milling machine?" Research design is used is inferential quantitative.
Datas collecting performed with laboratories test. Otherwise, surface roughness
datas is collected with dial indicator instrument. Results of this research are
(1) spindle revolution and feeding
variables in not free or have inter-influence to surface roughness
quality of MMC material, (2) Relation strength of spindle revolution and
feeding variables in not free or have
inter-influence to surface roughness quality of MMC material is weak. This research
conclutions are (1) spindle revolution and feeding variables is not free or have inter-influence
to surface roughness quality of MMC material, (2) Relation strength of spindle
revolution and feeding variables in not
free or have inter-influence to surface roughness quality of MMC material is
weak, The weakness of both parameters can be caused by cutter tool, material
properties, and measurement instrument are used.
