Abstract
The invention relates to a system of a method for controlling a machine tool, and a workpiece, in particular a milling blank, and the method for machining this workpiece, said machine tool comprising a robot arm movable in at least 2, in particular at least 3 spatial axes in a range of motion, said robot arm carrying, guiding and moving at least one workpiece, possibly by means of a workpiece holder, with a control unit for controlling the machine tool. The machine tool (62) comprises a sensor, in particular a spatially fixed optical sensor or is assigned said sensor, whose detection range (66) at least partially overlaps the range of motion. The workpiece (10) comprises a change in geometry, in particular a hole (12), is moved in the detection range (66) by the robot arm (70), and upon detection of the hole (12) by the sensor the control unit determines a reference point, reference axis and/or reference surface for controlling the machine tool (62).
