ABSTRACT
In milling process with spindle slope, the
milling process requires energy from milling machine. The greater the spindle slope
estimated to be the greater energy required by the milling machine.
Therefore, the machining
vibration that occurs was estimated to be very big. This study
aimed to determine the influence spindle slope to machining vibration in
milling machine with variations of depth of cut. This study used Milling
Machine Knuth Universal UFM 2 with vertical milling approach. The slope spindle
used was 300, 400 and 600. The machining
process parameters varied was the depth of the cut, while
feed and spindle speed were constant. The study results show
that the greater the spindle slope, the greater the machining vibration on the
up milling process and the down milling processes for all spindle
slope. Similarly with the influence of depth of cut to machining vibration
in milling process. The study results show that the change of depth of cut will
give a positive impact to machining vibration 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 down
milling process is greater than the up milling process.
Key words
: Machining vibration, spindle slope, depth of
