Acoustic Power Measurement of Machine Tools

Abstract

In evaluating the acoustic power of the noise of a machine tool, the acoustic intensity of the measurement surface around the machine must be measured, In the case of large machine tools, the measurement surface must also be made large. Therefore, considerable space for measuring intensity is required, and the number of measurement points and measurement costs increase.
If the acoustic power of the individual components of a machine tool were measured and added together, and if this total were to coincide with measurement of the acoustic power of the machine as a whole, the need to conduct single overall measurements of large objects such as machine tools would desappear. It would be sufficient to only measure the individual components of the machine and an estimate of the acoustic power of an machine entire system could be made immediately. This report will seek to validate this through the measurement of NC lathes.
