Characterization of Regrinded Cutting Tools#

© WZL der RWTH AACHEN

To what extent does the cutting tool performance decrease within the tool life cycle when milling nickel-based alloys?

 

Challenge and Motivation

  • Extensive tool wear in machining of new and advanced nickel-based alloys leads to high tool costs
  • The tools are regrinded several times to reduce tool costs
  • With several regrinding operations, a loss of performance of the cutting tools can be observed

Objectives

  • Evaluation of a possible performance loss of cutting tools in milling Inconel® 718 due to several regrinding operations
  • Identification of possible causes for performance loss
