Today I will share with you a few small questions about removing electrodes.

1. The area in the red circle is the area where the electrode needs to be removed. If the area is too large, it is difficult to observe. There will be many places to trim the electrode directly on it.

2. Usually, in this case, many people choose to copy a workpiece and cut a part of the workpiece with a split body. In fact, I can make a box and make contact with the workpiece. In this way, I can get the department I need.

3. The yellow surface in Figure 4 is the part where the electrode needs to be removed. You can choose to stretch the electrode discharge part. However, a red explosion occurs when it is stretched, as shown in the red circle in Figure 5. At this time, you can try to adjust the tolerance, but after adjusting the tolerance, it still doesn’t work.

4. Remove the two R angles at the red explosion point and find it after stretching. The exploding point on the left is eliminated, but the one on the right still exists after being stretched.

5. In fact, I can analyze that the reason for the explosion point is that the highest point has exceeded the curvature when the surface meets the surface and deformed. It is only necessary to offset the highest surface of the explosion point slightly downward so that this surface does not exceed the curvature. Go to stretch again, the explosion point is eliminated and stretched into a solid body.

6. Trim other parts again, cut the top surface flat with a trimmer, and then offset the side surface

7. Return to the workpiece and observe whether there is overcutting, and the electrode discharge position is OK

  After the above steps are completed, the removal of the electrode is complete,
