When the axis line of the cemented 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 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 should be as short as possible to reduce the impact of the milling cutter axis and the position of the workpiece on the impact load.
3. Use the correct tooth pitch of the milling cutter suitable for the process to ensure that there are not too many blades that mesh with the workpiece at the same time to cause vibration during cutting. On the other hand, ensure that there is enough when milling narrow workpieces or milling cavities. The blade engages with the workpiece.
4. Make sure to use the feed rate of each blade so that the correct cutting effect can be obtained when the chip is thick enough to reduce the wear of the tool. The indexable inserts with positive rake angle grooves are used to obtain a smooth cutting effect and the lowest power.
5. Select the diameter of the milling cutter suitable for the width of the workpiece.
6. Choose the correct entering angle.
7. The milling cutter should be placed in the correct position.
8. Use cutting fluid only when necessary.
