In order to study the influence of ultrasonic vibration on the formation mechanism of the cross section of sawing monocrystalline silicon,the equation of cutting trace of abrasive grain in radial vibration rotary sawing process was presented,and the trace of abrasive grain was simulated using the MATLAB.The experiments of radial vibration rotary sawing and conventional sawing of monocrystalline silicon were carried out respectively.After sawing,the micrographs of the cross section surfaces were analyzed wit...
