Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to detecting NG data of production equipment machines (NC machine tools) that process workpieces from parts drawing data and material drawing data using CAD (computer-aided design) or the like. Automatically created and consistent production system CAM (Computer Aided Manufacturing)
A tool setting device for automatic processing machines that searches and determines the tool to be used suitable for the processing content from the tool data file through interactive processing with graphic output and automatic processing in the process of creating processing information for automatic processing machines. Regarding.

[Conventional technology]

As a representative of flexible automated production systems, FMS is now in the practical stage. In an FMS, a computer operates schedule plans, machining/setup plans, tool supply plans, etc. online, but the structure of the machining information creation device that presents CAD data corresponding to the upper level and downloads it to the FMS. As for the current situation, it is poorly defined, fixed, partial, and fragmentary.

[Problem that the invention seeks to solve]

Most of the current CAD/CAM systems are fixed, partial and fragmented, and lack -i characteristics. Even if it were a series, the reality is that it lacks a system, lacks flexibility, and is not put to practical use. In other words, a CAD/CAM system that is suitable for a production system that incorporates cutting technology has not yet been established, and is therefore an incomplete CAD/CAM system. Machining information is not just 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 current CAM is already on the NC machine tool! ! The main purpose is to automatically create processing information for placed parts, but it has not gone so far as to take into account the evaluation of production methods in FMS and the like. On the other hand, CAD parts drawing data and material drawing data are currently nothing more than machining information that determines the final result, but in order to create NC data by utilizing CAD information, it is necessary to understand the machining concept. It is necessary to include information on cutting technology related to (setting up the machine to be used, determining the machining procedure, etc.), machining methods, arranging, combining, and determining parts in the optimal way on pallets, so-called setup methods, etc. There is. When describing the tool,
In most cases, tools are matched one-to-one with the workpiece, and there is no consideration of integrating or substituting common tools, and it is far from practical to automatically search for the tools to be used based on the processing technology. It lacked flexibility, versatility, and was inefficient.

The present invention was proposed in view of the above circumstances, and includes:
The object of the present invention is to provide a tool setting device for use in an automatic processing machine that is flexible, practical, precise, and efficient and can be used as part of a consistent processing information creation device required for FMS.

[Means for solving problems]

In the present invention, the means for solving the above-mentioned problems is to set the tool to be used by searching and determining the tool to be used that is suitable for the machining content from the tool data file in the process of creating the machining information of the automatic processing machine from the graphic information. The device includes: a tool-by-tool machining content data memory storing machining content data created with scheduled tool settings; and an integrated instruction data memory storing tool integrated instruction data for common machining content; A tool data file memory that stores tool data together with tool set data, a search standard data memory that stores tool type setting standard data, finish level setting standard data, and search range setting data, and a matching standard that stores matching standard data. A data memory, a machine data memory that stores machine specification data, a search data setting section that sets search data for each of tool type, tool code, tool diameter, and finishing degree, and a search data setting section that stores the tools used from the tool data file. The present invention provides a tool setting device for an automatic processing machine, which includes a tool search section for searching, and a verification/judgment section for determining whether the tool found by the search is suitable for machining contents and machine specifications.

[Effect]

In the present invention, the machining content data and tool integration standard data for each tool are read in, and the tool data file is searched for a match using the tool code, tool type, and two-tool diameter finishing degree as keys. For example, the machinable depth,
Items such as the main cutting edge angle are checked, and if they are satisfied, they are registered in the database as tool data used, and the tool type and finish level can be searched repeatedly by changing the values, and the number of repetitions is determined by the limit ranking for each. It can be managed by setting.

The criteria for tool searches and comparison judgments are subdivided and graded, and by repeatedly searching according to the set order, logical searches and judgments can be performed, realizing automatic searches based on processing technology content. I will do it.

Although the tool setting device to be used according to the present invention mainly relates to the tool search processing section 28 in the machining information creation device described above, it goes without saying that the device is not necessarily limited thereto.

FIG. 1 is a block diagram showing an example of a tool setting device according to the present invention. In Fig. 1, the tool setting device used is a CPU that also serves as the central processing unit of the device, a display 2 with a keyboard and its input/output board 2a, a machine data memory 4 that stores machine specification data, and a machine data memory 4 that stores machine specification data.

The search data setting section 74 includes a tool type setting section 74a, a tool code setting section 74b, a tool diameter setting section 74c,
It is composed of a finish level setting section 74d.

The used tool search section 75 includes a used tool search setting section 75a for associating search data with tool set data, and a used tool search processing section 75b for searching tool data based on the settings. has been done.

, a tool-by-tool machining content data collation/judgment section 76b that collates the data with the machining content data for each tool, and a machine data collation/judgment section 76c that collates the same data with machine data.

FIG. 3 is a flowchart showing the operating procedure of the above device. Hereinafter, the device described above will be explained in detail according to the operating procedure.

When the flow starts, the CPU 1 executes the search data setting section 7.
4, and as the 0th stage of the flow, the tool type setting standard data 72a in the search standard data is read into the tool type setting section 74a.

The stored content of the search standard data memory 72 has an output screen as shown in FIG. 4, and is composed of tool type setting standard data 72a, finish level setting standard data 72b, and search range setting data 72c. Ru. The tool type setting standard data 72a indicates the tool type: Permanent tool (=1); Dedicated tool for the tool normally set in the magazine (=2); Dedicated tool to be set in the magazine Standard tool (=3) ;A general-purpose tool (=4) that is outside the magazine but has already been assembled in the tool room? Assembly is represented by tools that can be assembled in a tool room, etc., and the search order and the number of positions in the order to be repeatedly searched are set.

The search order of the finishing level setting reference data 72b is determined by the finishing level of the machining content data, and up to five items can be set. The level 4E in the processing content data has the following meaning.

lO rough 20 out of 20 30 Finishing 40 Finishing 50 Precision finishing Moreover, the finishing degree of the tool data has the following meaning.

0 Rough/Semi-finishing 1 Roughing 2 Semi-finishing 3 Finishing 4 Finishing 5 Rough/Finishing 6 H6 7H7 8H8 9 Semi-finishing/Finishing search range setting data 72c is for registering up to which rank in the order is allowed. .

Now, in the 0th stage of the flow, the tool type setting standard data 72
A is read, but the standard for the search order is, as shown in Figure 4 (1) → (2) → (3) - (4), the standard for the search order is permanent tool - exclusive. The settings should be in the order of tool - standard tool - general purpose tool. In any case, when making this input, the operator specifies (3) if he intends to search up to a certain number, for example, even data prepared outside the magazine. This means that the necessary tool is first searched for from the permanent tools, and if it cannot be found, it is searched for from the dedicated tools, and if it is still not found, it is searched for from the standard tools, but it is not searched for from the general tools.

The basic reason for setting criteria for setting tool types is to increase the search speed as much as possible and to make the search contents more realistic and practical.

In the 0th stage of the flow, integrated instruction data (integrated instruction data memory 34) as shown in FIG. 5 is read into the tool code setting section 74b, tool diameter setting section 74C, and finishing degree setting section 74d.

The values for the tool code and tool diameter cannot be changed, so the conditions will be set as they are.
Since the finishing degree can be searched repeatedly in the same way as the tool type, the finishing degree setting standard data 72b in FIG. As the 0th stage, the search range setting data 72c shown in FIG. If the finish level is (10) rough, the tool search order will be (1) rough, (0) rough/medium finish, (5) rough/finish, but dirt will be specified as the second place. By doing (5
) Don't search for tools for roughing and finishing (but that's a good thing.

These search data settings are performed as the 0th stage of the flow.

As the 0th stage of the flow, the tool set data is sent to the used tool search unit 75 in the previous stage, Telua used tool search setting unit 75a.
As the 0th stage of the flow, the search key for the tool to be used set in each of the setting sections described above is also read.

As shown in FIG. 6(b), the tool set data has a one-to-one correspondence with the tool data in FIG. 6(a), and the tool type.

Data includes tool code, tool diameter, and finish level.

Based on the search data set by the search data setting section 74, the search is repeated until tool set data that matches the search data is found.

In addition, the search procedure for tool set data is first performed in the order set by the finishing level setting section 74d, and if it is still not found, the search is performed by moving down to the next order set by the tool type setting section 74a. go.

That is, in the example of Fig. 4, the tool type search order =
(3) When the finishing degree of machining content data - (10) roughness and the finishing degree search range of tool data = (2), the search ranking is as shown in the table below.

In the 0th stage of the flow, it is confirmed that the search setting process has been completed, and if it has not been completed, the search is repeated.

As the 0th stage of the flow, if tool set data is not found by the search process using the above search key,
Consider whether or not to issue an alarm and terminate the flow. When the tool set data is retrieved, as the [phase] stage of the flow, the used tool search processing section 75b in the latter stage of the used tool search section 75 is configured to have each item as shown in FIG. 6(a). Load tool data 3, which is file data for each tool, and as the 0th stage of the flow, compare each item of tool data 3 with the tool set data, for example] - tool type is item 11h3 of tool data 3, tool code is item N1
12. Search by comparing the tool diameter with item Arashi 6 and the finish level with item Yang 4. As already mentioned, the tool code and tool diameter cannot be changed, but the tool type and finishing degree can be searched repeatedly by lowering the priority order.

Further, the reason why the search for the tool to be used is processed based on the tool set data is that the search speed is increased.

Now, whether or not the discovered tool data is appropriate must be confirmed again. Therefore, in the 0th stage of the flow, the collation reference data (verification reference data memory 73) is reference data as shown in the collation determination section 77, which indicates the items to be collated, and holes are drilled for each item. A flag indicating whether to check machining other than holes, and data on their tolerances are input. Unrelated items have been marked with * since the beginning.

When the collation data is set as the 0th stage of the flow, as the 0th stage of the flow, the machining content data for each tool (machining content data for each tool memory 33) as shown in FIG. ) is read, and as the 0th stage of the flow, the following comparison judgment is performed on the machining content data for each tool. However, K: Machining content data, T: Tool data, C

○Pitch -C<T<K+C Figures 9 to 11 show which parts of the tool the above items refer to: FM (face mill), SM (shell mill)
, BR (poling).
The symbols in (w) correspond to the respective items of the collation reference data shown in FIG.

For each of these items, if the contents of the retrieved tool data and machining content data satisfy various conditions, the determination is OK; if not, an alarm signal is output.

Subsequently, in the [phase] stage of the flow, machine data as shown in FIG.
The memory 4) is read, and in the 0th stage of the flow, a check is made against the machine specifications. For example, strokes in three directions are shown in items Nl14 to Arashi 6 of the machine data (machine data memory 4), but as shown in FIG.
Its stroke (Kan 6) and the tool length of tool T (Fig. 6 (a)
) Due to the relationship between the magnet 7) and the machining area of the workpiece W, a situation may occur in which the magnet collides with other locations or cannot reach other locations. If there is a possibility that these situations may occur, an alarm signal is output.

The tool data for which the result of the comparison judgment is OK is registered in the used tool data memory 35 as the [phase] stage of the flow.

Finally, in the [phase] stage of the flow, if it is confirmed that all search processing is completed, the operation procedure ends.
