PENGARUH PUTARAN SPINDEL, GERAK MAKAN DAN KEDALAMAN POTONG TERHADAP GETARAN SPINDLE HEAD HASIL PROSES DRILLING
Abstract: The process of
drilling or often
referred to as
the drill is the simplest machining process
among other machining
processes. Usually in
the garage or workshop process is called the drill,
although this term is actually less accurate. The process of the drill is
intended as a process of making a round hole by using a drill (twist drill).
While the process of drilling is the process to expand / enlarge the hole that
can be done with a drill rod is not only done on the drill machine, but it
could also machine tool, machine freis, or drilling machines.
From the research results can be seen the effect of the parameters used
to the chatter values obtained chisel. Can be seen carving the smallest value
of the vibration generated from experimental data 1 is =0.6361 m/s2 at n = 136
rpm, f = 0,07 and a = 14 mm. While the biggest chisel vibration acceleration
values obtained from experimental data collection to 27 for =,4267 m/s2 at n =
681 rpm, f = 0,22 and a = 20 mm.
From the regression equation can be known parameters of the most
influential pieces of depth of cut. The results in general that the value of
vibration acceleration and determination, after
the meal motion raised the value of vibration acceleration chisel and
roundness are also growing, this was due to the greater movement of food is
used then the resulting anger is also getting thicker so that the required cutting force increasing
large. Consequently tangential force is also rising and causing the radial force and moment coupling.
Moments and radial forces which cause bending and twisting of the chisel,
consequently the greater the roundness deviation.
