(1) Materials Science Forum Vols. *** 495 where, fCLK is sampling frequency,N is sampling points, fo is sine wave frequency which is defined from 50Hz to 1000Hz, as shown in Table 1.
Because N is different at different band, X doesn't fluctuate greatly in the whole valid band, the higher is the band, Advances in Materials Manufacturing Science and Technology 496 the more slightly is fluctuating and the more accurate is the output signal.
It is Materials Science Forum Vols. *** 497 obvious that the vibration drilling force drops sharply, especially at the hole exit.
