Benchmark: Machining Ceramic Matrix Composites (CMCs)

Which surface qualities and processing times are achievable when combining ultrasonic-assisted milling and grinding?

Challenge and Motivation

  • Ceramic Matrix Composites (CMCs) are increasingly used within high temperature sections of turbo machines.
  • Machining of SiC/SiC is time- and cost-intensive.
  • Combining machining processes could improve surface quality and reduce processing time.


  • Evaluation of technologic and economic feasibility when combining Ultrasonic-assisted (UA) milling and grinding to improve the CMC machining performance.
