Use Case DIH

Use Case: CIIRC CTU/ DIH Scenario

QEM Management Approach in Precision Drilling Operations
Use Case Description:

Focus on monitoring of tool wear during drilling operation:

  • D6x10 mm hole, HSS spiral drill
  • Tool steel material
  • Hundreds of drilled holes

The goal is to capture signal variance with increasing tool wear.

7 selected sampled monitoring parameters
As-Is State:
  • Every drill is going to be worn during drilling. The worn cutting edge may cause vibration level change and increased cutting force.
  • It is not generally known what real-time measurable variables and extracted features can characterize the tool wear appropriately.
  • The key question represents optimal moment for tool change.
To-Be State
  • Feature (combination of features) well characterizing tool wear is identified.
  • Thresholds for tool change situation are identified and successfully applied.
  • Data acquisition based on National Instruments (HW, SW)
  • Modular solution for fast adaptation, adding sensors etc.
  • Possibility of CNC data synchronization (e.g. digital input reading)
