System for controlling a machine tool

A system for a method for controlling a machine tool with at least one replaceable tool and a workpiece, and for a method for machining the workpiece,

• wherein the machine tool comprises a robot arm movable in an area of motion along at least 2 spatial axes, which robot arm carries, guides and moves at least one workpiece, with a control unit for controlling the machine tool,
• wherein the machine tool (52) comprises or is associated with a sensor (46), having a detection range (42) that at least partially overlaps an area of motion of the machine tool,
• wherein a front face (34) of a tool shaft (22) of the at least one replaceable tool (10) is provided with a code (36),
• wherein the at least one replaceable tool (10) is moved by the robot arm (44) in the detection range (42),
• wherein when detecting the code (36) by the sensor (46), the code (36) is passed to a control unit (54) for identification of the tool (10), and
• wherein the control unit (54) is configured to perform identification of the tool (10) for controlling the machine tool (52) for machining, the machining being adapted to the identity of the tool (10).
