Abstract
A system for offsetting a CNC machining process includes transferring compensation variables through registers in fixed G-code programming of the CNC machine and offsetting the CNC machine without altering fixed G-code programming. Global compensation variables are applied to all feature programs of the CNC machining process, and local compensation variables are applied to only individual features or groups of features. The machine shifts position in response to the compensation variables.
