手押かんな盤の騒音分析

その他

This paper deals with noise behaviour of hand-feed planer. Noise level in no-load running, planing and vibratory-acceleration level of workpiece generated by planing were measured. The measuring direction of vibratory-acceleration was perpendicular to workpiece motion. The measurement instruments are a sound level meter, vibration meter, 1/3-octave band pass filter and high speed level recorder. Test results show that the source of noise is cutterhead in no-load running and in planing. Though vibratory-acceleration level of workpiece generated by planing increases, noise level increases little when feed speed increases in planing.
