When the axis of the carbide milling cutter coincides with or approaches the edge of the workpiece, the situation will be serious, and the operator should do the relevant equipment maintenance work:

1. Check the power and rigidity of the machine tool to ensure that the required milling cutter diameter can be used on the machine tool.

2. The overhang of the tool on the spindle is as short as possible to reduce the impact load of the milling cutter axis and the position of the workpiece.

3. Use the correct milling cutter pitch suitable for the process to ensure that there are not too many blades meshing with the workpiece at the same time during cutting to cause vibration. On the other hand, when milling narrow workpieces or milling cavities, ensure that there are enough blades and workpieces meshing.

4. Ensure the feed rate per blade so that the correct cutting effect can be obtained when the chip is thick enough, thereby reducing tool wear. Use indexable inserts with positive rake angle grooves to obtain smooth cutting effects and the lowest power.

5. Select a milling cutter diameter suitable for the width of the workpiece.

6. Select the correct main deflection angle.

7. Place the milling cutter correctly.

8. Use cutting fluid only when necessary.

9. Follow tool maintenance and repair rules and monitor tool wear.

Proper maintenance of carbide milling cutters can extend tool life and improve work efficiency.
