Abstract
A non-intrusive inter-process measurement technique to determine the diameter of laser-drilled holes is demonstrated. This allows holes to be analysed immediately after processing, before drilling additional holes in the same part. Remedial action can therefore be taken if necessary. The sensor also measures the position of the workpiece relative to the focal point of the drilling laser to ensure optimal processing.
