Blade Inspection
Blade Inspection
Jet engine turbine blades wear away at the outboard tips. They can be refurbished by welding additional material to the tip, and then machining the surface smooth. An automated system was developed to measure the blade surface just below the weld bead using a Renishaw MP12 CNC touch trigger probe. The measured data is then transferred via an RS232 serial link to a Windows NT Workstation, running the ACIS Solid Modeller kernel, for analysis.
