Core Exit Machining

Here are 2 examples of the system machining away excess material covering the vents on a nickel-alloy turbine engine casting. In the first, the casting pattern is a wax-welded assembly of doublet segments, so there is considerable positional variation within the ring. The intelligent part positioner first locates the airfoil’s angular position, then the robot measures its radial position and height with the cutting tool. Machining commences in this new datum reference.

In the second video, the robot loads the part in the fixture and uses a larger bur to clear the heaviest material, and then switches to a smaller bur to machine closer and in the corners.
