Abstract
A measurement targeting apparatus comprises a target body, a vessel with a channel, a fluid located within the channel in the vessel, and a pressurization system. The target body is selected from one of a photogrammetry target, a theodolite target, a construction ball, a touch probe target, a coordinating measurement machine probe target, a laser tracker target, and a laser projector target. The vessel has a centerline, has a substantially cylindrical portion capable of being received in a hole in a part, and is comprised of a material selected from steel, aluminum, and plastic. The vessel is capable of expanding when the fluid within the channel in the vessel is pressurized. The pressurization system is capable of pressurizing the fluid within the channel to cause the vessel to expand around the centerline.
