Abstract：

The blanking process on servo press was studied based on servo press．The pressure maintaining model was applied by reducing the slider speed in the fracture separation stage to decrease the blanking vibration and noise．Blanking experiments with different material thick plates were researched under different blanking clearances and slider movement models．Results show that with the blanking speed reducing and pressure maintaining in the blanking process，the blanking noise of Q235A,20 steel,A6061 and SUS304 stainless steel can be reduced．Compared with the conventional blanking model, the blanking noise level is lowered obviously under the pressure maintaining model for the first three materials，and the noise can be reduced maximally about 20 dB for Q235A at the blanking clearance of 7%t(t is the plate thickness)．SUS304 stainless steel is not sensitive with the blanking speed and clearance and the blanking noise level is high．
