Collaborative R&D Project 2017

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
