[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing machine type determination method, and more particularly to a processing machine type determination method in the case of performing composite processing using NC processing machines of different types depending on materials and processing shapes.

[0002]

2. Description of the Related Art Conventionally, this type of processing machine type determination is performed manually by each element constituting a processing shape.

[0003]

In the above-mentioned conventional processing machine type determination, the processing capability of each processing machine is taken into consideration.
Since each element that makes up the shape is done manually,
There is a problem that a lot of working time is required when the number of processing points is large or the shape is complicated and the number of elements is large. There is also a problem in that the determination of the type of processing machine depends largely on the intuition and experience of an engineer, and a skilled engineer is required to determine the optimum model.

Material / plate thickness table that defines the processing grade depending on the material and plate thickness of the product, processing information table that defines the processing machine name by the combination of the shape of the material to be processed and the processing grade, and the processing to be processed Read machining element information including material, plate thickness and machining shape for each element,
A processing machine name determining means for extracting a processing machine name corresponding to the processing element information from the material / plate thickness table and the processing information table,
It is configured by including a writing unit that records the processing machine name determined by the processing machine name determination unit in pairs with the processing element information.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.
The embodiment of FIG. 1 is configured to have a processing information reading means 1, a processing shape reading means 2, a processing machine determining means 3, a processing machine name writing means 4, a processing information file 5, and a processing shape file 6, The information file 5 has a material / plate thickness table 51 and a machining information table 52, and the machining shape file 6 has a machining shape table 61.

FIG. 2 is a diagram showing an example of the contents of the material / plate thickness table 51. In the table, the numerical values of 0, 1, 2 ... Show the processing grade numbers depending on the material and the plate thickness. In this example, the plate thicknesses 1.2 and 1.6 of the material SPCC are the same processing grade number 0. Have been given.

FIG. 3 is a diagram showing an example of the contents of the processing information table 52. As shown in the drawing, the machining information table 52 is defined by a shape type that represents a straight line, an arc, or the like as the type of machining shape, a conditional expression that represents the starting point Y coordinate = the end point Y coordinate, and the like by the length or radius of the shape as the state of the shape. It is a table in which processing machine types are assigned according to a combination of a processing shape classified by a processing range in which a range in which the processing machine can be changed is set and a processing grade of the material / plate thickness table 51.

FIG. 4 is a diagram showing an example of the contents of the machining shape table 61, which is composed of records for each machining element. Each record has a shape type indicating the type of the processed shape, element information such as material, plate thickness, start point coordinates, end point coordinates, etc. if the shape type is a straight line, and each column of the processing machine. At the end of the processing, the processing machine name is written in the processing machine column by the processing machine writing means 4.

FIG. 5 is a flow chart of processing of the embodiment shown in FIG. The processing of the embodiment shown in FIG. 1 will be described below with reference to FIGS. First, the material / sheet thickness table 51 and the processing information table 5 from the processing information file 5 by the processing information reading means 1.
2 is read (step 101). Next, the processing reading means 2 reads one record of the processed shape table 61 from the processed shape file 6 (step 102). The end of the file is determined based on the presence / absence of a record to be read (step 103). If the end of the file is reached, the process ends. Next, the processing machine determination means 3 performs processing for determining processing conditions (step 104). This corresponds to one record of the read machining shape table 61 and the machining information table 52. For example, if the shape type of the read record is a straight line, the straight line portion 52 of the processing information table is checked to find a column in which the conditional expression and the processing range of the processing information table 52 match the element information of the record. For example, if the start point X coincides with the end point X, a field of the conditional expression of start point X = end point X is taken, and further, the start point X, the start point Y, the end point X, and the end point Y of the element information of the record.
The length of the element is obtained by calculating the column including the length in the processing range of the processing information 52. Next, the processing grade number corresponding to the material and plate thickness in the element information of the record is selected from the material / plate thickness table 51. For example, in the example of FIG. 2, the material is SPC.
If C and the plate thickness are 2.4, the processing grade number is 2. Next, in the processing information table 52, the processing machine name is determined from the column obtained in step 104 and this processing grade number (step 105). In the element information, if the shape type is a straight line, the start point X = the end point X, the element length is 20, and the processing grade number is obtained, the processing machine B is determined in the example of the processing information 52 shown in FIG. Next, processing machine name writing means 4
The machining shape table 61
Write to the processing machine column of the corresponding record of (step 10
6). After this, the process returns to step 102 and step 102
The processing of 106 is repeated. The processing of 102 to 106 is continued until the processing of all records is completed.

[0011]

As described above, according to the present invention, the machining grade depending on the material and plate thickness, and the machining model name determined from the machining grade are registered, and the machining model name for a plurality of machining element information is registered. By selecting, it is possible to determine the model in the combined machining of NC processing machines without human intervention,
This has the effect of drastically reducing the work man-hours and enabling optimal selection even by a non-skilled engineer.
