CPC G05B 19/4145 (2013.01) [G05B 19/253 (2013.01)] | 8 Claims |
1. A method for automated precision control of a computer numerical control (CNC) machine to a workpiece comprising:
receiving via at least one visual input device at least one detectable marking on a workpiece;
decoding said at least one detectable marking and determining a stored and pre-defined movement routine of a cutting element attached to said CNC machine relative to said workpiece based on said at least one marking;
determining, using said at least one visual input device and/or another visual input device, a current position of a working end of said cutting element relative to said at least one marking; and
performing said pre-defined movement routine comprising cutting into said workpiece with said cutting element;
wherein said at least one marking is determined, in said step of decoding, to be any one of a polygon, square, circle, an x shape or a cross shape, and wherein the center of said at least one marking is a calibration point for determining the spatial offset of said at least one visual input device from the central axis of said working element along a horizontal plane.
