Abstract: An apparatus and method for manufacturing a workpiece using optical dimensioning. The apparatus comprises a tool configured to alter at least one feature of the workpiece. An imaging system is coupled to the tool and defines an optical axis. The imaging system is configured to capture a plurality of images of the at least one feature of the workpiece. A controller comprises one or more processors. The controller is configured to analyze the plurality of images to determine measured dimensions of the at least one feature of the workpiece. The controller is further configured to define a three-dimensional path for operating the tool by applying a predefined modification to the measured dimensions of the at least one feature of the workpiece.
