1) Check the power and rigidity of the machine tool to ensure that the diameter of the milling cutter used can be used on the machine tool and the overhang of the tool is as short as possible;
2) The number of teeth of the milling cutter is moderate to ensure that there are not too many blades meshing with the workpiece at the same time to cause vibration during processing. When milling narrow workpieces or cavities, there must be enough blade and workpiece engagement;
3) Appropriate feed per tooth in order to obtain a good cutting effect when the chip is thick enough to reduce tool wear. Positive rake angle inserts are used to obtain smooth cutting effect and the lowest power;
4) The diameter of the milling cutter suitable for the width of the workpiece;
5) Correct lead angle (45 degrees is suitable for general milling);
6) Appropriate milling cutter position;
7) Only use cutting fluid when necessary, dry milling usually has better tool life.
