To Study the Effect of Different Operating Parameters on Noise During Turning Operation in a Centre Lathe Machine

Abstract

ABSTRACT In our modern world, rapidly expanding environment one of the developing problems is that of “Noise”. In India, the industrial sector is growing rapidly and number of industries increasing at very fast rate. This has lead to noise pollution. Machine tool noise is one of the major source of noise in industries.

So, it is necessary to study noise generated by machine tools. Machine tool which is most commonly used in factory/workshop is the lathe machine. In the present work the effect of different operating parameters like cutting speed, feed and depth of cut on noise during turning operation in a centre lathe machine have been considered. First of all to find out the location where the sound pressure level is maximum, the sound pressure level measured in dB(A) near the machine at five different locations at distance of 0.5 m from the centre of each side of an machine for different combination of operating parameters. Sound power is then calculated using rectangular parallelopiped method at different cutting speed, feed and depth of cut and also predict the most significant parameter using the Taguchi method.

Frequency spectrum analysis in 1-1 octave band has been carried out at the location where the sound pressure level is maximum.
