What to do when the milling cutter vibrates

What to do when the milling cutter vibrates? Because there is a small gap between the milling cutter and the tool holder, the cutter may vibrate in the machining process. Vibration will make the cutting amount of the circular edge of the milling cutter uneven, and the cutting expansion is greater than the original set value, which will affect the machining accuracy and tool service life. However, when the processed groove width is too small, the tool can be vibrated purposefully, and the required groove width can be obtained by increasing the cutting expansion. However, in this case, the larger amplitude of the milling cutter should be less than 0.02mm, otherwise stable cutting cannot be carried out. In normal machining, the smaller the vibration of the milling cutter, the better.

In case of tool vibration, the cutting speed and feed speed shall be reduced. If there is still large vibration after both have been reduced by 40%, the tool reduction shall be considered

If the machining system resonates, the reason may be that the cutting speed is too large, the feed speed is too small, the rigidity of the tool system is insufficient, the clamping force of the workpiece is insufficient, and the workpiece shape or clamping essentials. At this time, measures such as adjusting the cutting parameters, increasing the rigidity of the tool system and increasing the feed speed should be taken
