An electronic system for compensating the dimensional accuracy of a 4-axis CNC machining system includes a CNC machining system configured to machine a feature into a part, a dimensional measuring device configured to measure a dimension of the part, and to provide an output corresponding to the measured dimension, and a compensation processor in communication with the CNC machining system and dimensional measuring device. The compensation processor is configured to receive the output from the dimensional measuring device, to calculate a plurality of CNC offsets, and to provide the offsets to the CNC machining system.
