Abstract
Vibration is a dynamic instability of the cutting operation caused by the interaction of the machined tools varied with the process. Surface irregularity, tool wear damage, and higher cutting force are all caused by vibration in the cutting process. This article investigated the experimental effects of vibration on CNC face milling dependent on sound amplitude. Constant spindle speed, feed rate, and various cutting depths are the parameters that have been considered for the simulation experiment. The machine produced chatter while cutting to various depths based on the Mastercam X9 software program during the machining process. The sound chatter received has been analyzed in REW (Room EQ Wizard) which estimated the amplitude of the acoustic and surface finish. The average roughness (Ra) and average maximum peak (Rz) testing results reveal 2.19 µm and 14.73 µm, respectively. The spectrogram has shown a 21.5 dB SPL (Sound Pressure Level) with a continuous oscillation from 200 Hz to 20 kHz at a peak time of 589.01 ms, ranging from + 90% to −90% sound impulse. Eventually, the low sound amplitude consumed short waves and low vibration, which resulted in a good surface polish with high frequency.
