A finishing apparatus including a central control machine having a computerized controller, at least one articulating device controlled by the central control machine and operable to move the machining tool, and at least one of a touch sensor apparatus and a visual sensor apparatus mounted to said machining tool and communicatively coupled to the computerized controller. The computerized controller configured to cause the finishing apparatus to position a machining element in contact with an exterior surface of a film cooled article, move the machining element along the exterior surface while maintaining contact between the machining element and the surface, identify an actual position of a film opening based on sensory feedback while maintaining contact between the machining element and the surface, and remove material from the exterior surface at the film opening using said machining element.
