Overview

Features & defects quantified during the inspection process include:

• Diameters measured at 1 degree increments.
• Overall shape conformity.
• Position, width, height, and area of all channels.
• Classification of channels into perimeter, interior, and defective classes.
• Development of a DPF channel grid that tags perimeter channels and alternating interior channels for plugging.
• Identification and quantification of common grid defects including:
  • Face cracks
  • Channel stitch
  • Channel wall gap
  • Deformed channels
