Abstract

In a molder, at least one rotatably driven tool (7, 8, 10, 11) is used to produce the structure (27) or contour on the workpiece (1) by workpiece removal. The workpiece positions along the workpiece (1) for producing the structure or contour are set depending on the data of the workpiece (1) and of the tool (7, 8, 10, 11). The data are transmitted to the machine controller which processes the CNC program based on the data during the passage of the workpiece (1) through the molder and moves the tool (7, 8, 10, 11) into the required positions via CNC drives depending on the workpiece position. The workpiece position is sensed during the passage of the workpiece (1) through the molder. In order to sense the workpiece position in the molder, at least one measuring element (18) is provided upstream and downstream of the tool (1), said measuring element (18) being connected to the machine controller and supplying signals that describe the advancing travel of the workpiece (1) to the machine controller. By way of the machine controller, the tool (7, 8, 10, 11) is moved into the respective tool positions in accordance with the signals.
