How to deal with the situation of vibration tool in CNC Machining

1. Use sharp blades to reduce the cutting force of CNC milling machine. Machine clip blades are divided into coated and non-coated blades. Non-coated blades are usually sharper than coated blades, because if the blades are to be coated, they must be passivated (ER treatment), because the sharp edge will affect the bonding strength of the coating at the edge.

2. When the cutting depth is fixed, the cutting force can be reduced by using small arc radius of the tool tip. Especially the radial cutting force, which is the main cause of vibration of slender rod tools or workpieces. Whether it is impact or milling. At the same cutting depth, the greater the radius of the tool tip arc. The vibration tendency of slender cutter rod is greater.

3. When choosing the cutting depth, avoid that the cutting depth is equal to the radius of the tool tip arc.

4. For the key cutting of sharp cutter of slender tool rod or the cylindrical turning of slender axle, the tool with 90 degree principal deviation angle is beneficial to vibration elimination. Whether it is turning slender axle or key hole of slender tool rod with cylindrical turning tool, it is always 90 degrees, and the radial cutting force produced by the tool with main deviation angle is the smallest. At the same time, the blade edge produces the largest axial force.

5. For the slender rod milling cutter, the circular blade milling cutter is most conducive to vibration reduction. Contrary to the agitator, the greater the radial cutting force, the greater the vibration of several tool bars. Therefore, in the face milling of deep-hole cavity of die, the NC milling machine usually uses 45 degree principal deviation angle milling cutter, if the cutting depth is less than Imm. Round blade milling cutter or ball cutter are often used.

6. When CNC milling machine uses slender rod end milling cutter to milling deep cavity, insertion milling is often used. Plug milling means that the cutter enters the cutter axially like a drill bit. When milling deep cavity, the diameter of the long rod is usually greater than three times the diameter of the cutter rod. We recommend the use of the axial feed cutter. However, the edge of the end milling cutter blade has a radial cutting edge with a certain width. The tool supplier has technical data to prove that the cutter has the maximum cutting edge width during insertion milling.

7. Vibration in milling of thin-walled workpieces is entirely caused by workpieces, which are called box or bowl parts. Because the vibration comes from the workpiece itself, it is mainly to improve the grip of the workpiece when processing the milling of such parts.

8. When boring the inner hole, the smaller the blade edge angle, the better. In this way, the secondary deflection angle is very large, the flutter contact area between the secondary cutting edge and the machined surface is small, and the flutter is difficult to turn into vibration. The extrusion opportunity of the secondary cutting edge is also small.

9. If the face milling cutter adopts unequal spacing milling cutter, the milling vibration can be reduced. Here “teeth” refer to blades. Face milling cutters of the same diameter (e.g. 100mm). If the three cutting elements are equal, the cutter head with five blades will surely produce 50% less milling force than the cutter head with ten blades.

10. Use blades with positive front and large rear angles. It is equipped with a light chip breaker. Such a blade has the smallest wedge angle in filing or milling, and of course it cuts lightly.
