Abstract:
1. A machining process calibration system for a workpiece, comprising: a robotic arm having at least five degrees of freedom and configured to follow a tool control path that maintains the robotic arm in an orientation substantially normal to a surface of the workpiece; a pocket forming tool mechanically coupled to the robotic arm during a pocket forming operation in which a plurality of pockets are formed in the workpiece at an angle substantially normal to the surface of the workpiece; a finishing tool mechanically coupled to the robotic arm during a finishing operation; and a depth measurement tool configured to measure a depth of the plurality of pockets before and after the finishing operation, wherein a differential between a measured depth of the plurality of pockets before the finishing operation and a measured depth of the plurality of pockets after the finishing operation is used to determine material removed across each of the plurality of pockets.
