Abstract

The objective of this study is to
investigate the effects of machining parameters on the acoustic frequency
developed during the machining of cold work tool steels. The machining tests
were carried out through a milling method with different machining parameters.
Analogue acoustic signals obtained via the microphone were converted and
digitized. During idle operation and cutting operation, the obtained spindle
sound recordings were subjected to Fast Fourier Transform (FFT) and converted
from the time domain to the frequency domain, and the statistical effects of
cutting parameters were investigated by use of analysis of variance. Cutting
speed was found to be the only influential factor for the acoustic frequency in
idle time. In the starting of machining, the feed rate, cutting speed, and
depth of cut were seen to affect the acoustic frequency, while the cutting
speed, insert material, insert radius, depth of cut, and feed rate were seen to
be effective in the later stages of machining.
