Abstract
A back spotfacing system having a machining apparatus with a through-hole cutter tool. The tool has an elongate member movable to coaxially extend through a hole in a workpiece from a first side of the workpiece, the workpiece coupled to the apparatus. The tool has a cutter element pivotal between a stowed position on the elongate member, a contact position with an inner surface of the hole, and an extended position extending radially from the elongate member. In the extended position, the cutter element extends to machine and back spotface a surface on a second side of the workpiece opposite the first side. The system has a power system for powering the apparatus and tool, and a measurement system coupled to the apparatus for measuring one or more hole exit positions of the cutter element and one or more surface contact positions of the cutter element on the surface.
