Abstract In order to find out the optimum input in terms of travel speed, the experiment was conducted by having a constant rotational speed with the increment of
travel speed. These variables were selected based on the pre-setting speed available on a universal milling machine of Milko 37. Different welded specimens were
produced by employing travel speeds of 29, 44, 54, 67, 86 mm/min, and constant
rotational speed of 910 rpm. The tilt angle of tool at 3°, tool shoulder diameter of
20 mm, and threaded cylindrical tool pin were utilized in this experiment setting.
With the increment of travel speed at a constant rotational speed (RPM), varying
contact conditions at the material interfaces were created. The result obtained for
this research were taken from visual analysis on surface and cross section of every
joint. Based on this result, the optimum travel speed for constant rotational speed
(910 rpm) is 29 mm/min.
