- Machine table 14 are integrated flush with the surface. This straight line extends orthogonal to the
- the workpiece 48 is a machined workpiece.
- the sensors 44a-f are configured so that the

- an external memory 58 which may be, for example, a cloud storage and are stored in the records of a database.
- the machined workpiece 48 can either be stored temporarily or it can be stored immediately, or it can be immediately moved back onto the feed table 12, for example by the handling device 32, for example rotated there by 90 °, and then split again (second cut).
- the machined workpiece 48 thus becomes an initial workpiece from which then further machined workpieces arise. This process may possibly be repeated several times
- the dashed line shows the movement of a trapezoidal workpiece 48 in FIG. 2
- Workpiece 48 all sensors indicate a change in the signal state at the desired times tl and t2. It can also be seen that knowing the speed of the workpiece 48 in the direction of movement 46 from the time difference t2-tl, the distance between the front edge 50a and the rear edge 50b can be determined. So it will be one
- the determined distance represents a geometric characteristic of the processed plate-shaped workpiece 48, which in this way by means of

- the differences between the actual values and the setpoint values are compared with limit values, and if the limit values are exceeded, an action is triggered. It is therefore triggered depending on the determined geometric property (in this case: strong trapezoidal shape of the machined workpiece 48) said action.
- This action may include: causing a handling of the workpiece; Outputting information to an operator; Storing a quality feature of the workpiece (as mentioned above); Applying information to the workpiece (as also mentioned above); Cause the workpiece to be discharged; Declaring the workpiece as broke;
- Workpieces lead which have in their interior not a perfectly closed structure but cavities. At an interface to the outside of these cavities are visible in the form of material craters.
- the senor 54 measures the distance of the lateral edge 52 from the abutment means 38 with a very high accuracy, for example, with an accuracy of a few hundredths of a millimeter, the said material craters in the form of the signal peaks 60 come to light. There is therefore a tolerance range (dashed lines in FIG. 7)
- FIG. 9 shows another operating situation with a
- FIGS. 10-12 in which the signal state changes of three sensors 44a-c arranged in a straight line and in the direction of movement 46 of the workpieces 48 and 51 immediately upstream of the saw line 20 and three in a straight line Line and in the direction of movement 46 of the workpieces 48 and 51 in the present example, immediately “downstream" of the saw line 20 arranged sensors 44d-f are explained.

- the sensors 44a-f are integrated flush with the surface of the machine table 14 so that the signal state of the sensors 44a-f changes when an edge of a workpiece moves over them.
- these sensors work on the principle of a Light barrier.
- the sensors 44a-f are drawn in a position that is greatly adjacent to the saw line 20. It goes without saying that she is also from the

- the machined workpiece 48 deforms banana-shaped as soon as it has been separated from the starting workpiece 51 because of the existing material stresses. When it moves from the starting work 51 further in the direction of movement 46 If its curved rear edge 50b passes over the downstream sensors 44d-f, these will not change the signal state at the same time.
- the outer sensors 44d and 44f change the signal state earlier than expected, that is, after a shorter movement path than
- FIGS. 13-15 show the same operating situations of FIGS. 10-12, but only one row of three sensors 44a-c is arranged downstream of the saw line 20 as viewed in the direction of movement 46. Because of
- Sesnors 44a-c are drawn strongly adjacent to the sawing line 20, but could in turn be clearly separated from it.
- the respective sensors 44a-c first change the signal state during the movement of the output workpiece 51 and the workpiece 48 pushed therethrough when the trailing edge 50b of the machined workpiece 48 passes over it, and again change the signal state when the leading edge 61a of the parent workpiece 51 moves over it.
