Abstract: In a machine comprising a spindle configured for performing a machine process in positional relation to a table, a method of operating the machine comprises fixing a probe to the spindle and fixing an object to the table. A first orientation position of the object relative to the spindle is determined while the table is positioned in a first table orientation. The table is re-oriented to a second table orientation, and a second orientation position of the object relative to the spindle is determined. A position of a table reference point along a first direction relative to the spindle is determined by averaging the first orientation position and the second orientation position, and a position of the spindle relative to the table is adjusted based on the position of a table reference point along the first direction.

Abstract: A computer controlled machining system is provided, and includes a multi-axis machining device that is configured to produce a workpiece based on a part print, which outlines nominal dimensions for the workpiece. A dimensional measuring device is configured to take or determine measured dimensions of the workpiece. A compensation processor is configured to take the measured dimensions from the dimensional measuring device and compare them to the nominal dimensions, and to determine a plurality of deviation sets from such comparison. The compensation processor transfers the deviation sets to the multi-axis machining device, which shifts a machine coordinate system based on the deviation sets.

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.
