[Conventional technology]

FMS is now in the practical stage as a representative automated production system that demands flexibility. In the FMS, the computer operates the schedule plan, machining setup plan, tool supply plan, etc. online, and from the presentation of CAD parts drawing data and material drawing data corresponding to the higher level, to the relevant F~1s. Currently, the structure of the downloaded processing information creation device is inconsistent, fixed, partial, and fragmentary.

[Problems to be Solved by the Invention] Most of the current CAD/CAM systems are fixed, partial, fragmented, and inconsistent.

Even if there were a series of them, the current situation is that they lack flexibility and are not put to practical use. In other words, the CAD/CAM system is incomplete, as a production system that incorporates cutting technology has not yet been established. Machining information is not just the NC data necessary for automatic operation of NC machine tools.

The decision as to what kind of concept and what kind of machining method to use for machining a part is greatly reflected in the NC data that is created. The main purpose of current CAM is to automatically create machining information for parts already placed on the NC machine tool, and FMS
It has not yet reached the point of considering the evaluation of production methods. On the other hand, CAD parts drawing data and material drawing data are simply processing information for determining the final result. (e.g., determining process steps)
It is necessary to include information on cutting techniques, such as processing methods, arranging, combining, and fixing parts on the bullet in an optimal manner, so-called setup methods, etc.

The problem here is, first, how to divide the machining process and determine the machines K to be used in order to improve the efficiency and equalize production. Second, how to arrange or combine parts on pallets for the divided processing steps,
There is a way to set up processing. Thirdly, how to conceptualize the machining method, and consider the processing of the tools to be used and the allocation of machining areas based on the machining shape and machining accuracy information, which leads from CAD to NC machining (consistency and This is the key point of flexibility.

The purpose of the present invention is to solve the problems mentioned above, and to provide flexibility and practicality that can be used as a part of a consistent processing information creation device required for FMS, etc. An object of the present invention is to provide a processing area division processing device for an automatic processing machine, which is equipped with the following.

[Failure to solve the problem]

In the present invention, a means for solving the above-mentioned problems is a machining area division processing device for an automatic processing machine that divides the machining area for each machining method through interactive processing with the machining data output screen and automatic processing. a standard data memory that prepares judgment criteria and setting criteria for region division; a stepped hole machining area determination unit that determines immersion or blurring from machining design data; a recess area division processing unit that deletes the recess area from the area; a division determination unit and its flag processing unit that assigns an identification code when there is another machine process area such as center processing or reaming processing in the stepped hole area; , a plurality of shape element determination units that determine the machining area step by step according to the shape type for each machining method based on the determination criteria that are missing in the machining area of the processing machine, and the divided areas based on the determination results. A machining area division processing device for an automatic processing machine, comprising a plurality of shape element division processing units that are registered in correspondence with setting standards, and a data memory for each machining method area that files created data. It is.

Shape types can be classified as shown in FIG. First, it is classified into six types according to the content of the machining process: surface, groove, pocket side surface, and 9-stage hole.
Furthermore, the boundary between an object and a space can be defined by a contour and a cross section or a basic single line and a cross section, and the outer circumference or inner circumference can be considered for the contour to indicate the processing range.

When setting the machining method, divide the immersion into a simple-shaped hole and the pocket into a machining start hole and two areas as necessary, and create a region for each machining method.

In the immersion, the area of the recess is divided until the remaining area becomes a simple shape. The method of division differs depending on the presence or absence of a prepared hole, the state of the material shape, the shape of the bottom, and dimensions such as diameter and depth.

For pockets, when the machining depth is deep, a pilot hole is drilled at the upper left corner to start machining, and when the cutting area of the area is large, the area is divided into two for pre-machining and post-machining of large-diameter tools. .

It consists of the depth of the prepared hole, diameter magnification, tip angle, clearance in the depth direction, etc.

FIG. 4 is a schematic diagram showing an example of outputting part of the reference data.

FIG. 5 is a flowchart showing the operating procedure of the installation process. In the figure, the number of each step corresponds to the number in FIG. 1 of the means implementing the procedure.

When the procedure is started, first, machining setting data is input to the stepped hole machining area determination unit 81, and if a recess exists, the recess is divided by the four-part area division processing unit 82 shown in FIG. Figure 6 (a) is an explanatory diagram showing the recessed part for installation, in which W is the workpiece, H is the part hollowed out during casting or pre-processing, and the diagonal line between the two is shown. This is the machining area, and in addition to simple installation machining, relief machining is shown for three recesses: groove PI in the end face direction, necking P2, and -aP3 in the inner diameter/inner circumferential direction. . Since these recesses can be determined from the shape data without using the reference data, first, these grooves are divided and deleted by the recess area division processing unit 82 to create a simple stepped hole shape, and then the main division processing is performed. Move to. Next, if the center machining division determining unit 83 determines that center machining is necessary, a flag is set in the center machining flag processing unit 84, and the reamer pilot hole straight line determining unit 85 determines that reamer pilot hole is necessary. If so, set a flag in the reamer prepared hole flag processing section 86.

FIG. 6(0) is an explanatory diagram of center machining, and a flag is determined by comparing each element in the diagram with the center machining term of the reference data shown in FIG. Figure 6 (c) is an explanatory diagram of the reamed pilot hole.The reamer machining allowance in the figure is compared with the standard data in Figure 4.For example, if the machining allowance is larger than the standard, a flag will not be set, and simple hole machining will be performed. As of 1.11 (extends).

The second stage of the procedure is the machining area dent/bottom fire determination section 87.
It is determined whether the shape of the machining area is a dent and there is no pilot hole. Only in the case of YES, the machining area is divided into dents/prepared hole division processing unit 88 , and in the case of the depression, the preparatory hole processing division processing unit 89 performs division processing. In any case, the presence or absence of a prepared hole in the divided area is determined by the processing area prepared hole determination section 90 via the OR gate 101. Figures 6 (D) and (E) are explanatory diagrams showing an example without a pilot hole, and Figure (D)
There is a dent in the center of the material, but the pilot hole is not open. In this case, the margin amount is set using the setting standard data shown in FIG.

If there is no pilot hole, the process is returned to the pilot hole machining division processing section 89 via ORG 102, and the region for the pilot hole machining is divided. The term without a hole is compared with each element shown in the figure (e), and it is determined whether to divide it or not. In addition, in FIG. 4, the reference diameter 1 and the reference depth 1 correspond to each other, that is, the reference for installation up to three stages is shown.

If there is a lower hole (including cases where the area of the pilot hole is divided and the remaining part is re-input), input that area to the pilot hole straight line determination section 9I and check whether the hole in the material is straight or not. Determine if there is. If the hole in the material is straight, the lower large bottom determining section 92 determines whether the bottom has a taper as shown in FIG. 6 (F) or is flat as shown in FIG. 6 (G). Based on the determination result, the lower six taper bottom division processing unit 94 or the pilot hole flat bottom division processing unit 95 performs division processing by applying the terms of the standard data of FIG. Ru. If the hole in the material is a stepped hole, the murder direction determination unit 9
In step 3, it is determined whether the step hole is expanding in the direction shown in Figure 6 (H) or in the pinching direction as shown in Figure 6 (S), and based on the determination result, the maximum expansion area is determined. The division processing unit 96 or the maximum pinched area division processing unit 97 divides the fourth
The division process is performed by applying the material expansion term or material sandwiching term of the reference data of the diagram.

In addition, the spreading direction is when the next processed surface is closer to the prepared hole side than the previous material surface, judging from the processing direction, the margin is on the other side from the cutting edge, and the pinching direction is the opposite. The surplus amount will be included on the same side as the machining allowance.

As mentioned above, the judgment and division process is repeated for the stepped hole.The basic principle is that first, as shown in Figure 7 (a), it is divided into ■ and ■ on the line side. If the conditions of the standard data are not met, the horizontal (or diagonal horizontal)
It is a change to division.

The above procedure was a flow showing an example of stepped hole processing, but
In addition, the WEZ of this embodiment has a processing area determination unit 9 for blurring and processing.
The pocket processing area shown in FIG. Pocket machining usually starts with drilling on the corner part C1 shown in the plan view of FIG. 8(A), so the radius of the corner part C1 and the depth shown in the side view of FIG. etc. become a problem. For the pocket term of the reference data in FIG. 4, the minimum diameter 3 area magnification and the prepared hole generation depth are the determination criteria, and the other criteria are the setting criteria.

The data divided as described above is filed in the processing method area data memory 30 as area data for each processing method.
