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 spindle speed. This study used Milling Machine Knuth Universal UFM
2 with vertical milling approach. The
slope spindle used was 300, 450 and 600. The machining process parameters varied was the spindle
speed, while feed and depth of the cut 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 spindle speed to
machining vibration in milling process. The study results show that the change
of spindle speed 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 spindle speed, the machining
vibration on the down milling process is greater than the up milling process.
Key words : Machining vibration, spindle slope, spindle, up milling, down milling
