| Abstract: | The EDM in-situ dressing technology is used to carry out the precision dressing experiment on the arc-shaped metal base superabrasive wheel.The results show that:compared with the traditional Compared with the"opposite grinding method",the precision and efficiency of the dressing are greatly improved:when the discharge gap is 55μm,the discharge current is 15 A,the duty cycle is 20%,and the rotation speed of the grinding wheel is 1200 r/min,the high precision grinding wheel with the contour deviation PV value of 4.58μm is obtained.The efficiency and accuracy of the modification were increased by 37%and 12.09%. |
