Experimental study on grinding force and surface quality of ultrasonic assisted grinding CFRP materials
Ultrasonic assisted grinding(UAG)tests are carried out on carbon fiber reinforced polymer/plastic(CFRP)using two types of grinding heads,one with disordered grain arrangement(plating)and the other with ordered grain arrangement(brazing),to compare and analyze the effect of the grain arrangement on the grinding force and surface roughness of the workpiece.The effect of grain arrangement on the grinding force,surface morphology and surface roughness of the workpiece is analyzed in comparison with conventional grinding(CG).The results show that,under the same test parameters,when ultrasonic-assisted grinding,the brazed grinding head can obtain smaller grinding force compared with the electroplated grinding head,and the grinding surface damage area is smaller and less in form.Therefore,the abrasive grains with larger height of exposure and better isotropy can play the role of ultrasonic vibration better.In addition,the surface roughness measured after ultrasound-assisted grinding is lower than that of ordinary grinding for both types of grinding heads.When ultrasound-assisted grinding was performed,the surface roughness obtained from brazed grinding heads is lower than that of plated grinding heads under the same parameter conditions.
