Investigations on edge rounding of holes and small geometric features
How to increase productivity when rounding edges and small features?
Challenge and Motivation
- Sharp edges and burr holes can increase both stress and strain and can lead to material failure. Edges and critical holes must therefore be rounded.
- Achieving tight geometric tolerances, high quality and productivity is difficult to reach.
- On-Machine Measurements (OMM) allow in-line adaptations of the process.
Objective
- Review of state of the art of OMM.
- Position detection and rounding of small features (e.g. blade tip)
- Proof of concept of combination tools and automated positioning of rounding tools relatively to the hole.
