BLISKS & IMPELLERS

 

NC programming of Blisks and Impellers is a complex task. It is often not enough to be able to program the theoretical shape and for a variety of reasons, these complex real-world metal-cutting applications often fail to deliver expected results.

Work piece and cutter deflection can compromise accuracy and contribute significantly to the deterioration of process capability.

TTL’s Adaptive Machining technology uses “in-process” feedback, and analyses intended versus achieved results. Decisions and corrections can then be made in order to maximise accuracy and yield.

On service-run components it is common to see significant complex shape variation between blades.

Where parts are weld or patch repaired or where they have been linear friction welded, our blisk repair and Impeller software modules provide fully automated aerofoil re-profiling whilst taking these variations into account.

This is where TTL’s two decades of experience in Adaptive Machining offers many advantages.

• Removal of hand blending and polishing
• Very smooth blends with parent material
• Easily controlled machining parameters
  
• Quick part set-up
  
• Hands-free operation
  
• Precise control of edge geometry
