Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an NC data generating apparatus for microjoint cutting.

[Conventional technology]

Generally, when creating NC data of this kind of NC data creating apparatus for micro joint cutting, it is necessary to pay sufficient attention to the cutting method, the method of taking out the workpiece, and the like.

In particular, for small workpieces, since there is a problem in how to take out after processing, without taking out from the fixed length material in the middle of processing, provided a plurality of 0.1-0.15mm joints on the outer periphery of the processing part There is a method in which a worker performs a work of separating a joint portion after completion of processing of a processed product arranged on a fixed-length material (called micro-joint cutting processing). In this case, when creating the NC data, it is indispensable to calculate the die allocation position in consideration of the joint.

[Problems to be solved by the invention]

In the conventional NC data creating device for cutting micro-joints described above, when creating NC data, it takes a lot of time to calculate the die allocation position in consideration of the machining method and the removal of the workpiece, and often, Therefore, there is a disadvantage that the data quality is reduced due to a calculation error.

[Means for solving the problem]

An NC data generating apparatus for cutting a micro joint according to the present invention includes a first storage unit for storing attribute data of a press die, a second storage unit for storing predetermined developed graphic data, and the first storage unit. Die data reading means for reading attribute data of the press die from the means, developed graphic data reading means for reading developed graphic data from the second storage means, and utilizing the developed graphic data displayed as a graphic screen A micro-joint cutting section setting processing means for interactively setting a predetermined micro-joint cutting section; and outputting predetermined mold allocation data in consideration of the setting of the micro-joint cutting section to select a desired mold. Die allocation processing means to be allocated, and NC data conversion for converting die allocation data obtained by the die allocation processing means into predetermined NC data. Configured with a processing unit, and a NC data output means for outputting said mold allocation data or the NC data.

〔Example〕

Next, the present invention will be described with reference to the drawings. First
FIG. 2 is a block diagram of an embodiment of the present invention, and FIG. 2 is a flowchart showing a series of operations of the embodiment. First
As shown in the figure, the present embodiment has a CRT 1 and a paper tape puncher 6 functioning as output means, a keyboard 2 and a mouse 3 functioning as auxiliary input means, a control unit 7, a mold data reading unit 8, and a developed figure. A storage / processing unit 4 including a data reading unit 9, a micro joint cutting / processing unit setting processing unit 10, a mold allocating processing unit 11, an NC data conversion processing unit 12, and an NC data output unit 13; First file 14 holding type attribute data
And a disk device 5 for storing a second file 15 having expanded graphic data.

Next, the operation of this embodiment will be described with reference to FIG. 1 and FIG.

First, the mold data reading unit 8 uses the keyboard 2 or the mouse 3 functioning as an auxiliary input means to control the attribute data of the press mold held in the first file 14 through the control operation of the control unit 7. A die reading process is performed to load the die (including the die code, type, size, presence / absence of heel, die mounting tension information, etc.) into the storage / processing unit 4 (step 101).

Next, the expanded graphic data reading unit 9 fetches the expanded graphic data held in the second file 15 into the storage / processing unit 4 by the keyboard 2 or the mouse 3 through the control operation of the control unit 7. For reading the developed graphic data is performed (step 102).

The expanded graphic data is stored in the keyboard 2 and the control unit 7.
Is output as a graphic screen on the display surface of the CRT 1, and the micro joint cutting processing section setting processing section 10 performs a micro joint processing for setting the micro joint cutting processing section interactively using the mouse 3. Is performed (step 103).

Next, in consideration of the micro-joint cutting processing section set in the above step 103, the mold allocating processing section
In step 11, first, a process of assigning an attribute to an assigned / unassigned line segment is performed (step 104), and then a process of assigning a die to the assigned segment is executed (step 105). When it is assumed that the line segment length allocated in step 105 is L and the mold length is 1, in step 106, it is first determined whether or not L = 1, and L = In the case of l, the die allocation processing unit 11 performs single-shot allocation processing (step 107). L ≠
If L> l, it is determined in step 108 whether L> l, and if L> l, step L
At 109, it is determined whether L ≧ 1.5l, and
If L ≧ 1.5 l, an overtaking allocation process is performed in step 110. If not L ≧ 1.5 l, it is determined in step 111 whether or not the nibbling mold. If it is the nibbling mold, it is determined in step 112 whether L ≧ l + sheet thickness. A determination is made as to whether or not it is. If it is determined at step 112 that L ≧ l + plate thickness, rib ring processing is performed at step 113.

It should be noted that when it is determined in step 108 that L> l is not satisfied, and when it is determined in step 111 that the die is not a nibbling mold, after the single-shot allocation processing in step 107, after the extra-punch allocation processing in step 110, and in the nibbling in step 113 After the processing, the NC data conversion processing unit 12 performs an NC data conversion process of converting the die allocation data into the NC data (step 114). The converted NC data is transmitted to the CRT 1 or the paper tape puncher 6. (Step 115).

FIG. 3 shows an example in which the developed graphic data is displayed on the screen of the CRT 1, and the operator interactively manipulates the micro joint cutting part through a mouse operation while observing the display screen. Can be specified. FIG. 4 shows the state after the micro joint cutting part has been designated.
This is an example of a screen display of a CRT. On the screen, the microjoint-cut portions are indicated by circles at four corners. FIG. 5 shows an example in which the status of the die allocation is output on the CRT screen, and FIG. 6 shows the result of converting the die allocation data into NC data on the display screen of the CRT. It is an example.

〔The invention's effect〕

As described above in detail, the present invention is applied to the NC data creating apparatus for microjoint cutting, and when creating NC data, the die layout position to be performed in consideration of the machining method and the removal of the workpiece. Since the calculation process by humans is eliminated and the micro joint can be specified interactively with the graphic screen, the data creation time is shortened and the quality of NC data can be improved.
