Which roughing strategy in milling is best suited with regard to different blisk designs?

Challenge and Motivation

  • The selection of an economical roughing strategy is highly influenced by the blade geometry of the blisk.
  • Lack of process knowledge makes the selection of a suitable roughing strategy difficult.


  • Economical, technological and ecological evaluation of different roughing strategies (e.g. conventional, high-feed milling, side milling, trochoidal milling, plunge milling).
