摘要:In high speed face milling, noise can be broadly categorized as idling noise and cutting noise. Idling noise mainly consists of aerodynamic noise. A mathematical model is developed based on the Ffowcs Williams-Hawkings Equation. The noise predicted with the mathematical model compares well with the experimental observations. The characteristics of aerodynamic noise with the different model parameters (number of teeth, tooth spacing) and locations of observation points are investigated. The directivity of noise is found and the peak value of sound power can be moved from the rotating frequency to higher frequency. This investigation can provide theoretical foundation for the design of face milling cutters with low noise.
