PENGARUH KECEPATAN POTONG, GERAK MAKAN DAN KETEBALAN PEMOTONGAN TERHADAP GETARAN BENDA KERJA PADA PROSES SEKRAP
Abstract: Shaping machine
is a machine
tool used to
modify the surface
of the workpiece into a flat
surface, good story, angled, and the flow corresponding to the shape and
size desired. Shaping
process is a
process similar to
the lathe, the difference is in motion the process of
intersection. In the process shaping machine tools with straight main motion
back and forth vertically or horizontally. Chisel cut motion in
a straight motion
of the workpiece
is translational. In
this case the workpiece and cutting tool is at rest
moving straight translation. At the chisel to move back, move the workpiece
also bait (feeding). So your back will chisel stuck in a moving workpiece.
Shaping machinery industry in the world used to work on areas of flat, convex,
concave, disorderly, in a horizontal position, vertical, or oblique, etc.
From the research results can be seen the effect of the parameters used
to the chatter values obtained chisel and roundness. Can be seen carving the
smallest value of the vibration generated from experimental data 1 is =0.5562
m/s2 at n = 5 m/min, f = 0,2 and a = 1 mm. While the biggest chisel vibration
acceleration values obtained from experimental data collection to 27 for =
5,1659 m/s2 at n = 11 m/min, f = 0,6 and a = 2 mm. The results in general that
the value of vibration acceleration, after the feeding motion raised the value
of vibration acceleration of the workpiece increases, this is because the
larger the feed motion is used then the resulting anger is also growing thicker
so that the necessary cutting force increases. As a result, the tangential
force is also up and cause the radial force and moment coupling.
