【Abstract】 The modelling Identification of DCFC in three-dimensional wave-on-wave cutting and the influence on DCFC of the three cutting parameters (cutting speed, feed rate and cutting depth) are investigated. The method of discrete weighted function series and random excitation technique have been adopted.更多还原
