Pengaruh Kemiringan Spindel Dan Kecepatan Pemakanan Terhadap Getaran Mesin Frais Universal Knuth UFM 2

Abstract

In milling process with spindle slope, the milling process requires energy frommilling machine. The greater the spindle slope estimated to be the greater energyrequired by the milling machine. Therefore, the machining vibration that occurswas estimated to be very big. This study aimed to determine the influence spindleslope to machining vibration in milling machine with variations of feed. This studyused Milling Machine Knuth Universal UFM 2 with vertical milling approach. Theslope spindle used was 300, 400 and 600. The machining process parameters variedwas feed while depth of the cut and spindle speed were constant. The study resultsshow that the greater the spindle slope, the greater the machining vibration on theup milling process and the down milling processes for all spindle slope. Similarlywith the influence of feed to machining vibration in milling process. The studyresults show that the change of feed will give a positive impact to machining vibra-tion on the up milling process and the down milling processes for all spindle slope.For the same spindle slope and depth of cut, the machining vibration on the downmilling process is greater than the up milling process.

Key words: Machining vibration, spindle slope, depth of cut, up milling, downmilling.
