A VMC that's a CMM. (Casebooks).

When Audi Performance Racing (APR) brought machining operations in-house, it purchased a Fadal Performance Series VMC 4525 for machining Inconel 625 exhaust-manifold castings. However, the Auburn, Ala., racing-products company soon discovered another use for the vertical machining center--as a CMM for reverse engineering.

Using the machine's probing cycle, APR plots the coordinates of a stock manifold to create a representation of where its mating flanges are located for the turbo head and cylinder-head sides.

Once this relationship is captured, the values go to the CAD system.

"The VMC 4525 is ideal for digitizing or reverse engineering because it provides accuracy of 0. …
