How do the grinding process and the tungsten carbide grade affect the cutting tool performance?


Challenge and Motivation

  • Extensive tool wear in machining of new and advanced alloys leads to high tool costs
  • Grinding process affects tool performance, dependent on carbide grade (different sensitivity)
  • Increased wear resistance leads to higher productivity


  • Phenomenological analysis of key performance driver (interactions between carbide grade and grinding parameter) with regard to process behavior (tool wear, cutting force)
  • Identification of potentials for improvement of cutting tool performance
