Process Vibrations due to Inconstant Workpiece and/or Tool Behavior#

What is the main reason for irregular vibrations in the milling process?

 

Challenge and Motivation

  • Vibrations in milling lead to higher surface damages, tool wear and sound emissions. 
  • Depending on the material batch, the actual tool microgeometry and the clamping situation, vibrations can occur irregular within finishing milling operation.

Objective

  • Identify root-causes for irregular vibrations.
  • Analysis of vibrations energy for Blisks from different material batches. 
  • Analysis vibrations for every blade before and after tool change.
