1) When moving the worktable or spindle, the moving speed should be correctly selected according to the distance to the workpiece to prevent collisions when moving too fast.
2) When programming, determine the correct processing technology and processing route according to the actual situation, and prevent the workpiece from being scrapped or cut off in advance due to insufficient processing position or insufficient edge strength.
3) It is necessary to confirm whether the program and compensation amount are correct before thread cutting.
4) Check whether the electrode wire tension is sufficient. When cutting the taper, the tension should be reduced to half of the usual.
5) Check whether the feeding speed of the electrode wire is appropriate.
6) Choose open processing or close processing according to the actual situation of the workpiece, and minimize the distance between the nozzle and the workpiece on the premise of avoiding interference. During close processing, the distance between the nozzle and the workpiece is generally 0.05 to 0.1 mm.
7) Check whether the jet selection is reasonable, use high-pressure jets for roughing and low-pressure jets for finishing.
8) Pay attention to observe and judge the processing stability when starting the cut, and adjust in time when defects are found.
9) During the processing, the cutting conditions should be inspected and supervised frequently, and the problems should be dealt with immediately.
