Abstract

In the world of the manufacturing industry, the machining process is one of the
main processes in the metal manufacturing, one of them is the turning process. In
the turning process it is difficult to get good product quality, this is caused by
several factors such as determining the spindle rotation speed, and the angle of cut
to be used. The vibration of the tool and the surface roughness of the workpiece
greatly affect the quality of the product being made. Vibration on the chisel will
cause a lack of accuracy in the measurement of the product being made, The level
of workpiece surface roughness is very important for planning machining processes
related to friction, fatigue resistance, and wear. The main objective of this study
was to determine the effect of the ideal cutting angle and spindle rotation speed to
produce tool vibration and low surface roughness in St 42 steel material in the
turning process. This research is an experimental study using materials with a
diameter of 20 mm and a length of 100 mm, with 3 kinds of cutting angles and 3
kinds of spindle rotation speed. The results of this study can be concluded that the
spindle rotation speed of 400 Rpm with an angle of cut of 80º produces the lowest
vibration of 0.34 mm/s and the lowest level of surface roughness is obtained at a
spindle rotation speed of 500 Rpm with an angle of cut of 80º which is equal to
13.756 µm.
