Sensor-assisted Analysis of Tip Repair Process via LMD and Adaptive Milling

© Fraunhofer ILT

How can sensor-supported online QA be achieved for sensitive processes such as tip repair?


Challenge and Motivation

  • Challenging LMD based tip repair process due to the changing of heat flow characteristics.
  • Investigation of dependency between melt pool temperature and LMD process parameters as well as further process steps for tip repair processes.


  • Acquisition of pyrometry data to enable adaptation of LMD process parameters (e.g. laser power) and correlation with adaptive milling process.
  • Pyrometer supported design and improvement of robustness of the tip repair process.
