Core Exit Machining

Here, the system was used to machine away excess material that covered the vents on a nickel-alloy turbine engine casting. 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, where the amount of excess material is measured and a precise contour is created.
