Method for controlling a machine tool

A system for controlling a machine tool and a workpiece and for machining the workpiece, comprising

• a machine tool,
• a workpiece, and
• a control unit for controlling the machine tool,
• said machine tool comprising a robot arm movable in at least 2 spatial axes in a range of motion,
• said robot arm configured for carrying, guiding and moving at least one workpiece,
• wherein the machine tool (62) comprises a fixed sensor or is assigned said fixed sensor,
• wherein a detection range (66) of the fixed sensor at least partially overlaps the range of motion of the workpiece,
• wherein an exchangeable tool (40) or the workpiece (10) comprises a code (52),
• wherein the workpiece (10) is movable in the detection range (66) by the robot arm (70), and
• wherein upon detection of the code (52) by the fixed sensor, the control unit is configured to carry out identification of the workpiece (10) and/or the tool (40) for controlling the machine tool (62) to perform a machining process adapted to an identity of the workpiece (10) and/or the tool (40).
