1. Divide the center and copy the number. After each centering is completed, copy the working coordinate number first, and then check from the beginning to see if the distance between the center and the two sides is the same to ensure that the centering and copying are correct.

2. Select the knife, install the knife, set the knife, copy the Z axis coordinate number. Select the appropriate tool according to the programming list. Before installing the tool, clean the tool head and nozzle completely. After installing the tool, use a calibration table to check whether the tool has deflection. After the knife is copied, check it from the beginning to prevent the right knife from being wrong, and the wrong number of copies will cause major losses to the company.

3. Transfer program and start processing: use single block execution before cutting, adjust the transfer speed and feed speed to the slowest, lower the tool slowly, watch the machine tool show the Z axis margin, check if there is any abnormality, if there is any abnormality Press the pause button immediately, find the reason and deal with the abnormality, and adjust to the appropriate speed to start processing after everything is normal.

4. During the processing, pay attention to investigating whether the processing is abnormal, the knife is not worn, and the sharpening of the tool should be suspended to ensure normal processing.
