1) When moving the worktable or spindle, select the correct speed based on the distance to the workpiece to prevent collisions caused by excessive movement.
2) When programming, determine the correct machining process and routing based on the actual situation to prevent workpiece scrapping or premature cutting due to insufficient machining position or insufficient overlap strength.
3) Before wire cutting, verify that the program and compensation amount are correct.
4) Check that the wire tension is sufficient. When cutting tapers, reduce the tension to half of the normal value.
5) Check that the wire feed speed is appropriate.
6) Choose open machining or close machining based on the actual situation of the workpiece. Minimize the distance between the nozzle and the workpiece while avoiding interference. For close machining, the distance between the nozzle and the workpiece is generally 0.05 to 0.1 mm.
7) Check that the jet flow is appropriate. Use a high-pressure jet flow for roughing and a low-pressure jet flow for finishing.
8) Observe and assess the machining stability at the start of cutting, and make adjustments if any defects are detected.
9) During the processing, the cutting conditions should be regularly inspected and monitored, and any problems found should be addressed immediately.
