- Output workpieces 12 defined, resulting in a height of the intended for splitting stack of starting workpieces 12.
- the production order also defines the material to be used and - this will still play a role - a desired quality (target quality feature) on the machined workpiece (reference numerals 14 and 74 in Figure la and lb), ie a target value for the above-mentioned size D.
- Cutting plan Also, from manufacturing job 78 to saw 80 configuration, the data on the stack height (height of the stack of workpieces to be split) and the material and quality desired are transferred.
- data concerning the tools that is to say the main saw blade 60 and the scoring saw blade 62, of the first machine tool 10 are also provided. These include one or more of the above-mentioned in detail "a characteristic of the tool characterizing quantities B", in particular a current tool state.
- Machine tool 10 required in block 80 process parameters are automatically detected by the sensor devices 44-47, others are in turn entered by the operator 68.
- the process parameters entered by the operator 68 are checked and adjusted if necessary. To do this
- Such a process model 84 may be
- the size A which characterizes the first machining operation including, for example, the machining task
- the size B characterizing a property of the tool 60, 62 for example type of tool, tool condition
- Property of the workpiece 14 characterizing size C (for example, the material). Also belongs to the
- Optimization variables is optimal or are.
- Process parameters in a function block 86 may also simply be provided in their entirety, without being previously input by the operator, by the process model 84 or a process database 88 upstream of the process model 84. This process database 86 will be discussed in detail below.
- the configuration 80 of the first machine tool 10 is followed by a function block 90, which represents the first machining operation in the first machine tool 10, in this case the division of the starting workpiece 12 into divided workpieces 14. Subsequently, in a function block 92, an identification of the edited through the first editing process
- Adhesive label on which a workpiece 14 uniquely identifying feature (identifier), such as a bar code, is applied to the workpiece 14
- the identification identifies not only the workpiece 14 as such, but also the specific first machining operation (for example by date and time) with which the workpiece 14 was produced.
- a linkage of the identifier of the workpiece 14 with the specific first machining operation, by which the workpiece 14 has been produced, is produced, for example, in the process database 88 mentioned above.
- a process data record is created (corresponding to the above-mentioned data record E), which for a specific first machining operation or a specific machined workpiece 14
- Process data represents, so for example, the actually used material of the workpiece 14, the actual tool data, the actual
- a functional block 98 represents the transport of the workpiece 14 from the first machine tool 10 to the second machine tool 72, in the present case as an example to the edge processing device.
- Function block 98 will therefore be the first at
- a not shown sensor for example a
- Adhesive label existing identifier is identified.
- the operator 68 could the
- an actual quality of the workpiece 74 obtained by the first machining operation is determined. As has already been explained several times, this can be done by an inspection by the operator 68, which is the result of For example, assessment then enters at the input device 70b or at one of the other input devices 70a or 70c.
- the sensor device 48 which is arranged in the second machine tool 72, can also be used for determining the actual quality.
- the existing sensor technology of the second machine tool 72 can also be used for the evaluation of the machining quality of the workpiece, and properties of the workpiece detected during the machining by the second machine tool 72 can be passed to the first machine 10 for further evaluation. The corresponding value was designated above by the letter D.
- Function block 96 feedback of the created at or immediately after the first machining operation
- Function block 104 confirmed quality feature
- Process data record by another process data namely the value determined in the function block 102, which is the
- process data sets (designated above by the letter E) are stored, which
- Tool identifier a diameter of the tool, a geometry of the tool cutting, a number of
- Tool status Sizes which characterize a machining task, for which purpose, for example, a height of the stack of workpieces to be split belongs (package height), and the type of processing, for example separating cut,
- process data sets stored in the process database are also used in function block 84, as was also already explained above, to create an algorithm, namely the above-mentioned process model.
- process data records are used in function block 109, possibly even first
- quality feature can be used not only for the formation of a process data set, but also for comparison with a desired or predetermined value of the quality feature, as it results from the production order 78 and the configuration 80 of the first machine tool 10.
- This desired or predetermined value (desired quality variable) is therefore retrieved in a function block 108 from the function block 80 (configuration of the first machine tool 10) and compared in a function block 110 with the actual quality variable determined or detected in the functional block 102.
- a function block 112 if the actual actual quality size is worse than the target quality size, then a notification is issued to the operator 68 that the just-checked
- Workpiece 74 is to be considered as scrap and must be produced again. This will be automatic too Reported back to the production planning 76, so that such a part is automatically integrated into the further production planning. It is understood that in the course of processing the
