[0031]
The modes of the plurality of patterns 59 include two modes, ie, a beginner mode pattern A and an expert mode pattern B as shown in FIG. 3 as an example.
[0032]
The beginner mode has a configuration in which the number of items of input information is relatively small, and the number of operations of the input parameter and the processing parameter 37 as a database is relatively large.
[0033]
For example, referring to FIG. 3, regarding the input data calculation processing in the beginner mode, the operation performed by the operator may be to input the material size / plate thickness / material, the product size / number, and the presence / absence of the edge cut.

[0035]
In the beginner mode, the input screen 61 and the instruction drawing viewed by the operator are relatively simple. For example, referring to FIG. 3, a display screen on which input items and instructions for an operator are specifically displayed one by one, for example, in an interactive format, and an image showing the material placement status, collection direction, inversion, etc. It has become.
[0036]
On the other hand, the advanced player mode has a configuration in which the number of items of input information is relatively large, and the number of processing processes of the processing parameter 37 based on the input information and database information is relatively small.

[0043]
Hereinafter, the plurality of patterns 59 will be described in detail by specifically taking up two patterns, a beginner level pattern A and an experienced person (advanced person) high level pattern B.
[0044]
In the pattern A, when the minimum necessary conditions are input, the NC device calculates the optimum cutting processing conditions according to the internal processing parameters 37 and operates each driving device.
[0045]
FIG. 4 shows a work piece for taking out n pieces of products having a product dimension of length U and width V from a work W of which the material is steel plate, the plate thickness is T, and the material dimensions are width X and length Y. This indicates that the portions of a, b, c, and d on four sides of W are to be cut off, and will be described on the assumption of this example.
[0046]
The input data of this pattern A is only the plate thickness T, material, material dimensions X and Y, product dimensions U and V, the number of products n, and the necessity of edge cutting.
[0047]
The CPU unit 31 calculates machine operating conditions based on the input data while referring to the machining parameters 37 of the memory unit 29. In other words, the number of products that can be taken from the material is calculated, the required number of materials m is calculated, and the ear cutting amount a of one material is calculated. The other ear cut amounts b, c, d are calculated in the same manner as a. Also, an operation procedure instruction to the operator is calculated. As a result of this calculation, the operator's operation procedure is simple as shown in FIG. 5, and it is only necessary to follow the displayed instructions.
[0048]
On the input screen 61 at the time of actual cutting, the necessary number of materials m is displayed as shown in the display 1 of FIG. After confirming this display, the operator presses a confirmation button 69.
[0049]
Then, a command is issued from the CPU unit 31 to each drive unit, the back gauge 17 is positioned at the ear cutting amount a, the upper blade 1 and the lower blade 3 are positioned at an appropriate clearance amount, and other air support is necessary. Optional actions are performed.
[0050]
After the operation of each driving device is completed, the input screen 61 displays an image and an instruction indicating the abutting direction of the workpiece W against the back gauge 17 as shown in the display 2 of FIG. Instructions are displayed. The operator works according to this instruction, and starts the shearing machine 5 by stepping on the foot switch. In addition, although a code | symbol is not displayed on the actual input screen 61, the code | symbol is described here for convenience, in order to make description easy to understand.
[0051]
After cutting the edge cut a, a command is issued from the CPU unit 31 to each drive unit, the back gauge 17 is positioned at the ear cut amount b, and other necessary optional operations are performed.
[0052]
After the operation of each of the driving devices is completed, the input screen 61 displays an image and an instruction indicating the abutting direction of the work W against the back gauge 17 and an instruction for starting shearing on the input screen 61 as shown in the display 3 of FIG. Is displayed. The operator works according to this instruction, and starts the shearing machine 5 by stepping on the foot switch.
[0053]
In the following, the instructions for the ear cuff c, the ear cutter d, and the product cutting process are given on the input screen 61 in the same manner as described above.
[0054]
As described above, the pattern A can be appropriately cut by a novice operator with minimum necessary information.
[0055]
Next, the pattern B for high-level operators (expert mode) will be described in detail. In pattern B, the operator basically instructs to input all NC data. Therefore, the operator can specify detailed machining know-how.
[0056]
For example, as shown in FIG. 9, when the plate thickness and material are input as the input data, the standard clearance and the standard rake angle are automatically displayed. In another example, items such as those described in the items of operator and input data calculation processing in the expert mode in FIG. 3 are displayed.
[0057]
Referring to Fig. 9, for each process, back gauge (B / G) dimensions, front gauge (F / G) dimensions, number of cuts, clearance (standard clearance by default), rake angle (standard rake angle by default) Instructs whether to input scrap material or product. Further, as an option, an instruction to input whether or not the workpiece W is returned to the front by the return conveyor, an instruction to use the reverse plate presser, an instruction to use the air support, or the like is input.
[0058]
When the above data is input, on the input screen 61 at the time of actual cutting, as shown in FIG. 10, a back gauge positioning completion lamp 71, a front gauge positioning completion lamp 73, and a top dead center display lamp 75 are displayed. Is displayed, and when any one of the lamps is lit, the current value 77 of the data in the lit lamp is displayed. Further, the input data for three processes is displayed, and the data of the process that is actually executed is displayed in reverse video.
[0059]
Therefore, the operator at the advanced level can specify the necessary cutting processing conditions in detail according to the needs of the pattern B, and appropriate cutting processing is performed based on this input data.
[0060]
As described above, operators such as beginners and experienced persons can switch to one mode by selecting one pattern 59 from a plurality of patterns by the mode selection unit 63 according to their own function level and machining needs. In accordance with the selected mode, an appropriate processing parameter 37 is selected or calculated based on the basic input information and the information in the database 43 by the calculation input auxiliary unit 65, and the processing items to be automatically input are changed. In addition, it is possible to give an instruction for an appropriate cutting process with a minimum amount of information and to give a detailed instruction. From the drive control unit 67, an operation command for the optimum cutting process is given to various drive units based on the input information from the basic information input unit and the calculation input auxiliary unit 65, so that the optimum cutting process is performed efficiently and efficiently. Can be done.
[0061]
In addition, this invention is not limited to the example of embodiment mentioned above, It can implement in another aspect by making an appropriate change.
[0062]
