ABSTRACT
In milling process with slope of work piece,
the milling process requires more energy from milling machine. The greater the
slope of work piece 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 influence the slope of work piece 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 of work piece used
was 300, 450 and 600. The machining process
parameters varied was spindle speed while feeding and depth of cut were
constant. The study results show that the greater the slope of work piece, the
greater the machining vibration on the up milling process and the down milling processes
for all slope of work piece. Similarly the influence of slope of work
piece 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 same the slope of
work piece and spindle speed, the machining vibration on the down milling
process is greater than the up milling process.
