1) When moving the worktable or spindle, the moving speed must be correctly selected according to the distance from the workpiece to prevent collisions when moving too fast.
2) When programming, the correct processing technology and processing route should be determined according to the actual situation, so as to 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 tapers, the tension should be turned down to half of normal.
5) Check whether the feeding speed of the electrode wire is appropriate.
6) According to the actual situation of the workpiece to be processed, choose open processing or close processing, and shorten the distance between the nozzle and the workpiece as much as possible under the premise of avoiding interference. During close contact processing, the distance between the nozzle and the workpiece is generally 0.05-0.1mm.
7) Check whether the jet selection is reasonable, use high-pressure jet for rough machining, and low-pressure jet for finishing.
8) Pay attention to observe and judge the processing stability when cutting, and adjust in time if any defect is found.
9) In the process of processing, it is necessary to check and supervise the cutting conditions frequently, and deal with problems immediately when they are found.
