Machine tool for producing a workpiece of predefined length

2:

• The machine tool of claim 1,
• wherein the at least one actuable slide element is configured to be actuated by the workpiece via at least one contact portion of the at least one actuable slide element.

3:

• The machine tool of claim 2,
• wherein at least one contact portion of the at least one actuable slide element forms a stop for the workpiece.

4:

• The machine tool of claim 1,
• wherein the at least one actuable slide element is mounted so as to be displaceable in the longitudinal direction between the drivable stop element and the cutting tool.

5:

• The machine tool of claim 1,
• further comprising:
• at least one light barrier which is arranged on the cutting tool and is configured to determine at least one zero position on the workpiece or to define the at least one zero position for machining by the cutting tool by at least one light signal which is transmitted to the workpiece and is reflected by the workpiece, or is a non-reflected light signal.

6:

• The machine tool of claim 5, further comprising:
• a control and regulating unit which is connected at least to the cutting tool, to the drivable stop element, and the at least one light barrier via a signal connection,
• wherein the control and regulating unit is configured to activate the drivable stop element via the signal connection in order to move the workpiece translationally into the machining position.

7:

• The machine tool of claim 6, further comprising:
• a display and operating unit which is connected at least to the control and regulating unit via a signal connection and is configured to query at least the predefined length of the workpiece.

8:

• The machine tool claim 1, further comprising:
• at least one sensor unit configured to detect a presence of the workpiece at least at a first point in time and at a second point in time.

9:

• The machine tool of claim 8,
• wherein the at least one sensor unit is arranged on the at least one actuable slide element.

10:

• The machine tool of claim 1,
• wherein the frame is comprises, at least in part, a table which has a work plate configured to receive the workpiece.

11:

• The machine tool of claim 1,
• wherein the frame has a receiving portion for the workpiece between the drivable stop element and the cutting tool, which receiving portion extends at least 2000 mm in the longitudinal direction.

12:

• The machine tool of claim 1,
• wherein the drivable stop element is designed-configured to releasably fasten at least one portion of the workpiece.

13:

• The machine tool of claim 1, wherein the drivable stop element is mounted on the frame so as to be displaceable in the longitudinal direction.

14:

• The machine tool of claim 1, wherein the at least one actuable slide element is mounted on the frame so as to be displaceable in the longitudinal direction.

15:

• The machine tool of claim 3, wherein at least one contact portion of the at least one actuable slide element forms the stop for the workpiece transversely to the longitudinal direction.

16:

• The machine tool of claim 6, wherein the control and regulating unit is configured to activate the drivable stop element via the signal connection in order to move the workpiece translationally into the machining position as a function of at least one light signal of a light barrier which is transmitted to the workpiece and is reflected by the workpiece or is a non-reflected light signal.

17:

• The machine tool of claim 10, wherein a groove or recess, which extends in the longitudinal direction, is formed on the work plate for the displaceable mounting of the at least one actuable slide element and/or for guiding the drivable stop element.
