A system, method, and device for automated precision control of a computer numerical control (CNC) machine to a workpiece. The system receives via at least one visual input device at least one detectable marking on a workpiece. The system decodes the at least one detectable marking and determines a stored and pre-defined movement routine of a cutting element attached to the CNC machine relative to the workpiece based on the at least one marking. The system then determines, using the at least one visual input device and/or another visual input device, a current position of a working end of the cutting element relative to the at least one marking. Finally, the system performs the pre-defined movement routine including cutting into the workpiece with the cutting element.

A method is described of machining a workpiece which is clamped in a fixturing element and is processed by a tool movably mounted on a CNC machine tool.

The fixturing element is integrally constrained to a frame of the CNC machine tool, then an optical scan of a geometry present in a portion of the workpiece is carried out. From digital data obtained during the optical scan, a coordinate of the geometry is determined in a reference system integral with the frame; and digital data, in particular coordinates, relating to a predetermined sequence of machining operations are processed to generate machining coordinates in the reference system integral with the frame for an actuator of the tool, said machining coordinates being such that the tool applies the pre-established sequence of machining operations on the workpiece at said coordinate.
