ABSTRACT 

A lathe is a rotating machine that utilizes a spindle motor and a feed motor, each of which is capable of generating vibrations as a result of their rotation. Besides the vibrations originating from these motors, the cutting process of the workpiece also plays a major role in increasing the overall vibration level. This study was carried out using a turning machine number 1214 at the Production Machine Laboratory of Politeknik Caltex Riau (PCR). In this experiment, a facing process was performed with three different cutting depths of 0.5 mm, 0.75 mm, and 1 mm. For each cutting depth variation, 15 data samples were collected within a time domain of 4 seconds. The cutting tool used was a carbide facing lathe tool. Vibration measurements were taken using a vibration tester type VM-6380 available at the PCR Production Machine Laboratory. During the cutting process, the probe of the vibration tester was mounted on the toolpost to detect the occurring vibrations. The results were expressed in the form of displacement, velocity, and acceleration along three directions: vertical, horizontal, and axial. The analysis revealed that the maximum vibration amplitude occurred along the axial direction with a cutting depth of 1 mm, achieving 0.097 mm, whereas the minimum amplitude was found in the vertical axis at a cutting depth of 0.5 mm, with a measurement of 0.032 mm.

Keywords: Lathe machine, Facing process, Cutting depth, Vibration analysis.
