How to Reduce the Vibration During the Milling Process?


In milling, there are often many reasons for vibration. These reasons may be due to the limitations of the cutting tool, tool holder, machine, workpiece or fixture. To reduce vibration, some strategies need to be considered. As UKO is a professional milling cutter manufacturer, let’s talk about how to reduce the vibration caused by the limitation of cutting tools during the milling process.

  • For face milling, the direction of cutting force must be considered:
    • When using a 90°milling cutter, the cutting force is mainly concentrated in the radial direction. In long overhang conditions, this can cause the milling cutter to sway; however, when milling thin-walled/vibration-sensitive parts, the small axial force is beneficial.
    • The 45 degree milling cutter can generate evenly distributed axial and radial forces.
    • The round insert milling cutter directs most of the force upwards along the spindle, especially when the depth of cut is small. In addition, the 10°milling cutter transmits the main cutting force to the spindle, thereby reducing vibration caused by long tool overhang.
  • Choose the smallest possible diameter for the process.
  • DC should be 20-50% greater than ae.
  • Choose a coarse pitch and/or a differential pitch cutters.
  • Lightweight milling cutters are advantageous, such as milling cutters with an aluminum alloy body.

For unstable thin-walled workpieces, use large entering angle = small axial cutting force; for long tool overhang conditions, use small entering angle = high axial cutting force.

UKO professionally provides a variety of CNC tools, and milling inserts are one of our superior products.
