When the axis line of the carbide milling cutter coincides with the edge line of the workpiece or is close to the edge line of the workpiece, the operator should do the following equipment maintenance work:
1. Check the power and stiffness of the machine tool to ensure that the required diameter of the milling cutter can be used on the machine tool.
2. The overhang of the tool on the spindle should be as short as possible to reduce the impact of the milling cutter axis and workpiece position on the impact load.
3. Use the correct milling cutter pitch for the process to ensure that there are not too many blades meshing with the workpiece at the same time to cause vibration. On the other hand, when milling narrow workpieces or milling cavities, make sure there are enough The blade engages with the workpiece.
4. Ensure that the feed per insert is used so that the correct cutting effect can be obtained when the chips are thick enough, thereby reducing the wear on the tool. Indexable inserts with positive geometries for smooth cutting results and minimal power.
5. Select the diameter of the milling cutter suitable for the width of the workpiece.
6. Select the correct main declination angle.
7. The placement of the milling cutter should be correct.
8. Use cutting fluid only when necessary.
