Abstract
An electronic system for compensating the dimensional accuracy of a 4-axis CNC machining system includes a CNC machining system configured to machine a plurality of features into a part, a dimensional measuring device configured to measure a plurality of dimensions of the part, and to provide an output corresponding to the measured dimensions and a compensation processor in communication with the CNC machining system and dimensional measuring device. The CNC machining system includes a global coordinate system, and at least one feature being defined relative to a local coordinate system that is translated from the machine coordinate system. Additionally, the compensation processor is configured to receive the output from the dimensional measuring device, to calculate a plurality of CNC offsets, including at least one local offset, and to provide the offsets to the CNC machining system.
