  Next, the processing procedure of the numerical controller according to the present invention will be described. Here, description will be made in the order of sticky note information registration processing, sticky note information editing processing, sticky note information search processing, and processing restoration processing based on sticky note information.

(Stick note information registration process)
First, the registration process of sticky note information of the numerical controller will be described. FIG. 4 is a flowchart showing a processing procedure of sticky information registration processing of the numerical control device, and FIG. 5 is a diagram for explaining sticky information registration processing of the numerical control device.

  When registering sticky note information, the operator displays a screen for creating sticky note information (step S110). That is, the screen display control unit 33 of the numerical control apparatus 1 displays a screen for creating sticky note information on the screen display unit 32. When a desired screen is already displayed on the screen display unit 32, it is not necessary to display a screen on which tag information is to be created.

  The operator inputs a sticky note registration instruction 45 for registering sticky note information to the numerical control device 1 (input means 11 shown in FIG. 2) (step S120). As a result, the numerical control apparatus 1 starts sticky note information registration processing (sticky note pasting processing).

  When a sticky note registration instruction 45 is input from the operator, the sticky note conversion unit 35 requests status information from the screen display control unit 33, and information (status information) being displayed on the screen display unit 32 from the screen display control unit 33. Receive. When the tag conversion unit 35 receives information being displayed on the screen display unit 32 from the screen display control unit 33, the tag conversion unit 35 converts this information into tag information (for example, tag Y1) (step S130). Specifically, as shown in FIG. 5, information in the screen 61 displayed on the screen display unit 32 includes “PM mode”, “nozzle open”, “plate thickness (20.0 mm)”, “processing speed”. “Adjustment (0)”, “Machining conditions (E 0)”, “Machining speed (FA 0.000)”, “Offset (H1 = 0.010)”, “Taper angle (A 0: 0: 0)”, etc. State information (text data 63) indicating the processing state of the image, image data 62 being displayed on the screen, and the like are created as a tag Y1. The sticky note conversion unit 35 adds identification information (ID) for identifying the sticky note Y1 to the sticky note information (sticky note Y1) when creating the sticky note information.

  In addition, when a sticky note registration instruction 45 is input from the operator, the sticky note registration control unit 34 sends instruction information to the processing information registration unit 36 so as to create and register the processing information. The processing information registration unit 36 extracts processing information (for example, processing information X1) corresponding to the tag information (information displayed on the screen display unit 32) created by the tag conversion unit 35 from the main storage unit 31, and the tag conversion unit 35 is associated with the converted sticky note information (sticky note 1) (creation of processing information). Here, the processing information registration unit 36 creates processing information at the timing when the tag registration instruction 45 is input from the operator.

  Specifically, the machining information registration unit 36 extracts the NC program 51, the machining conditions 52, the H variable 53, and various parameters 54 from the main storage unit 31 via the screen display control unit 33 in order to extract machining information. (Extract all at once). For example, the machining information registration unit 36 collectively extracts information such as “E1 IP1 OFF” and “E2 IP2 OFF2” as the machining conditions, and collectively extracts information such as “L1 N1 M20” as the NC program. Also, information such as “H1 0.010” is extracted as an H variable and information such as “Z1 0.000” is extracted as various parameters (Z specifications).

  That is, the machining information registration unit 36 here collectively extracts invariant information such as an NC program and information that changes in accordance with the progress of machining processing such as machining coordinates as machining information corresponding to the tag information. As a result, the machining information registration unit 36 can extract invariant information such as the NC program and information corresponding to the timing when the sticky note registration instruction 45 is input from the operator (information corresponding to the progress of the machining process). It becomes. The processing information registration unit 36 adds identification information (ID) of tag information corresponding to the processing information to the processing information when generating the processing information. Further, when extracting the invariant information such as the NC program, the machining information registration unit 36 may extract only the NC program used in the machining, or may extract all the NC programs.

  In this example, the processing information X1 and the tag Y1 correspond to each other, and the ID of the tag Y1 is added to the processing information X1. Further, the processing information X2 to X4 correspond to the sticky notes Y2 to Y3, respectively, and the IDs of the sticky notes Y2 to Y4 are added to the processing information X2 to X4, respectively.

  The sticky note conversion unit 35 generates NC program number, processing condition number, offset number, processing speed memory area address, as information for specifying the attribute data inside the processing apparatus from the sticky note information when creating the sticky note information. The address of the graphic change memory area may be added to the tag information. In this case, the sticky note conversion unit 35 extracts the NC program number, the processing condition number, the offset number, the address of the processing speed memory area, the address of the graphic change memory area, etc. from the processing information extracted by the processing information registration unit 36. Append to

  The tag conversion unit 35 stores the created processing information in the tag storage unit 43 (tag registration) (step S140). Further, the machining information registration unit 36 stores the machining information created as information in the machining apparatus in the machining information storage unit 44 (collective storage of machining information) (step S150). Thereby, the numerical control device 1 can store the detailed information (processing information and tag information) related to the processing of the processing device so that it can be easily searched.

(Editing sticky note information)
Next, tag information editing processing of the numerical controller will be described. FIG. 6 is a flowchart showing the processing procedure of the tag information editing process of the numerical controller, and FIG. 7 is a diagram for explaining the tag information editing process of the numerical controller.

  For example, when the numerical control apparatus 1 performs the sticky information registration process described with reference to FIGS. 4 and 5, there is a case where it is desired to edit the sticky information by adding a predetermined comment or the like to the sticky information. In addition, after processing the workpiece with the processing device and registering the sticky note information with the numerical control device 1, the workpiece is measured to check the workmanship, and according to the measurement result. There are cases where it is desired to add a predetermined comment or the like to the tag information. In these cases, the operator inputs a tag content change instruction 48 to the numerical control device 1 (input means 11 shown in FIG. 2) in order to change the tag information.

  The screen display control unit 33 of the numerical controller 1 causes the screen display unit 32 to display information (such as a list of tag information) on the screen display unit 32 based on the tag content change instruction 48 from the operator. (Step S210).

  The operator inputs instruction information for specifying the edit target of the tag information (the tag content change instruction 48 including information specifying the edit target) to the numerical control device 1 (input unit 11 shown in FIG. 2). On the screen of the screen display unit 32, the operator designates the tag information editing target (position) using, for example, a mouse pointer or a predetermined button (not shown) provided in the numerical control device 1. Thereby, the screen display control part 33 of the numerical control apparatus 1 specifies the edit object on tag information (step S220).

  The screen display control unit 33 determines whether the editing target on the specified tag information is text data 63 or image data (step S230). When the screen display control unit 33 determines that the editing target on the specified tag information is the text data 63 (Yes in step S230), the screen display control unit 33 transmits information for instructing the tag text editing unit 41 to edit the text. At this time, the screen display control unit 33 causes the screen display unit 32 to display the editing target (text data) on the specified tag information as a tag content editing screen.

  The operator inputs a desired comment or the like to the text data displayed on the screen display unit 32 via the input unit 11. At this time, the operator inputs a comment by specifying a position for inputting the comment or the like using a mouse or the like. For example, a comment indicating that “the processing speed is reduced” is input to the numerical control device 1.

  Thereby, the screen display control unit 33 causes the input comment or the like to be displayed on the screen display unit 32 together with the text data. The screen display control unit 33 transmits the input comment, information about the input position of the comment, and the tag information input with the comment to the tag text editing unit 41 together with the displayed text data.

  The tag text editing unit 41 rewrites the text data in the tag information based on the information sent from the screen display control unit 33. Here, the sticky note text editing unit 41 pastes the comment input by the operator on the text data based on the information related to the input position of the comment. Thereby, the sticky note text editing unit 41 edits the sticky note information to new sticky note information (step S240).

  The sticky note text editing unit 41 registers the edited sticky note information in the sticky note storage unit 43. When the tag information having the same ID as the ID of the tag information after editing has already been registered in the tag storage unit 43 (when the tag information registration by the tag conversion unit 35 has been processed), the tag text editing unit 41 Overwrites (revises) the tag information after editing in the tag storage unit 43 (step S250).

  If the screen display control unit 33 determines that the editing target on the specified tag information is not the text data 63 (image data) (No in step S230), the screen display control unit 33 instructs the tag image data editing unit 42 to perform image editing. Send. At this time, the screen display control unit 33 causes the screen display unit 32 to display the editing target (image data) on the specified tag information as a tag content editing screen.

  The operator inputs a desired comment or the like to the image data displayed on the screen display unit 32 via the input unit 11. At this time, the operator inputs a comment by specifying a position for inputting the comment or the like using a mouse or the like.

  As a result, the screen display control unit 33 causes the screen display unit 32 to display the input comments and the like together with the image data. Further, the screen display control unit 33 transmits the input comment, the information regarding the input position of the comment, and the tag information input with the comment to the tag image data editing unit 42 together with the displayed image data.

  The tag image data editing unit 42 rewrites the image data in the tag information based on the information sent from the screen display control unit 33. Here, the tag text editing unit 41 pastes the comment input by the operator on the image data based on the information related to the input position of the comment. Thereby, the sticky note text editing unit 41 edits the sticky note information into new sticky note information (step S260).

  The tag image data editing unit 42 registers the tag information after editing in the tag storage unit 43. When the tag information having the same ID as the tag information after editing is already registered in the tag storage unit 43 (when the tag information registration by the tag conversion unit 35 has been processed), the tag image data editing unit 42 ) Overwrites the tag information after editing in the tag storage unit 43 (step S270).

  Note that the sticky note text editing unit 41 and the sticky note image data editing unit 42 are not limited to editing state information (sticky note information) being displayed on the screen display unit 32, and the text search unit 40 searches and displays the screen display unit 32. You may edit the processing information displayed on.

(Search processing for tag information)
Next, the tag information retrieval process of the numerical controller will be described. FIG. 8 is a flowchart showing the processing procedure of the tag information search processing of the numerical control device, and FIG. 9 is a diagram for explaining the tag information search processing of the numerical control device.

  For example, a predetermined operator may process a workpiece using a processing apparatus and then take over the processing process to another operator. In such a case, the operator who performs the next processing process performs the processing process with reference to the tag information and the processing information registered in the numerical controller 1.

  Further, there are cases where it is desired to view the processing history by the processing device and the tag information created by the numerical control device 1. For example, in such cases, it is necessary to cause the numerical control device 1 to search for desired tag information and extract the desired information.

  First, a searcher (operator) for sticky note information or processing information has a sticky note search instruction 47 for instructing to directly search for desired information from sticky note information stored in the numerical controller 1 (sticky note storage unit 43), or A tag search instruction 47 for instructing to search for desired information from the tag information displayed on the screen display unit 32 is input to the numerical control device 1 (input unit 11 shown in FIG. 2) (step S310).

  If the text search unit 40 determines that the input sticky note search instruction 47 is instruction information for directly searching for desired information from the sticky note information stored in the numerical control device 1 (Yes in step S310), the sticky note information is included in the sticky note information. The registered character string is accepted. The operator inputs a text string for requesting search into the numerical control apparatus 1 (input means 11). At this time, the operator inputs a character string by specifying a search condition such as regular expression or fuzzy search. For example, a machining condition such as “PM * machining condition * V0” (including the letters “PM” and the letters “machining conditions” and the letters “V0”) is input. The character string and search conditions input to the numerical controller 1 are input to the text search unit 40 (step S320).

  The text search unit 40 searches the sticky information corresponding to the character string and the search condition from the sticky note information in the sticky note storage unit 43 using functions such as regular expression and fuzzy search based on the input character string and the search condition. (Full text search) is performed (step S330). The text search unit 40 transmits the search results to the screen display control unit 33, and the screen display control unit 33 displays the search results (such as a list of sticky notes) collectively on the screen display unit 32 (step S340).

  On the other hand, when the information cooperation tag search unit 39 determines that the input tag search instruction 47 is the instruction information for searching for desired information from the state information displayed on the screen display unit 32 (No in step S310), the tag Information on the processing device to be searched (for example, a normal processing device screen including the processing condition number) designated by the search instruction 47 is displayed on the screen display unit 32 (step S350).

  The operator designates information (a character string such as a processing condition number) to be searched for from information displayed on the screen display unit 32. The operator designates a range of a desired character string with a mouse pointer on the display screen of the screen display unit 32, for example. Thereby, the screen display control unit 33 specifies a character string to be searched (step S360), and transmits the specified character string to the information cooperation tag search unit 39.

  Based on the character string transmitted from the screen display control unit 33, the information cooperation tag search unit 39 searches the tag information in the tag storage unit 43 for the tag information including the character string transmitted from the screen display control unit 33 ( Full-text search) (step S370). The information cooperation tag search unit 39 transmits the search result to the screen display control unit 33, and the screen display control unit 33 displays the search result together on the screen display unit 32 (step S340).

  Here, the text search unit 40 searches for the tag information including the designated character string from the tag information in the tag storage unit 43, but the text search unit 40 uses the processing information in the processing information storage unit 44. Processing information including a designated character string may be searched.

  Here, the text search unit 40 (information cooperation tag search unit 39) searches for tag information including a character string specified from the tag information in the tag storage unit 43. The tag search unit 39) may search for the tag information itself based on the identification information of the tag information. Furthermore, the text search unit 40 (information cooperation tag search unit 39) may search for processing information corresponding to the searched tag information based on the identification information of the tag information.

In this case, the machining information is extracted based on the tag information created by the numerical control device 1, and the machining information is set as the machining information for the next machining process and the workpiece is processed.

  Specifically, the text search unit 40 and the information cooperation sticky note search unit 39 search the sticky note storage unit 43 for sticky note information to be restored by the procedure described with reference to FIGS. At this time, the information cooperation tag search unit 39 extracts the processing information (identification information) corresponding to the tag information (identification information) searched by the text search unit 40 from the processing information storage unit 44 and manages the tag search result management together with the tag information. This is input to the unit 38. The text search unit 40 and the information cooperation tag search unit 39 cause the screen display unit 32 to display the searched tag information. The operator specifies sticky information corresponding to the processing information to be restored (step S410), and inputs a processing information restoration instruction 46 including the identification information of the sticky information to the numerical control device 1 (input unit 11).

  When a processing information restoration instruction 46 that restores (reproduces) processing conditions and the like is input from the operator to the numerical control device 1, processing information corresponding to the tag information (searched tag information) designated by the operator is displayed on the screen. The information is displayed on the unit 32 (step S420).

  The processing information restoration unit 37 processes the processing information corresponding to the tag information specified by the processing information restoration instruction 46 from the tag information (identification information) and the processing information (identification information) input to the tag search result management unit 38. (Identification information) is extracted. The processing information restoration unit 37 stores processing information corresponding to the extracted identification information in the main storage unit 31. The machining information restoration unit 37 stores the new NC program 51, machining conditions 52, H variables 53, and various parameters 54 as machining information corresponding to the tag information (processing information to be restored) in the main storage unit 31 (step S430). ). As a result, it is possible to set (restore) the processing information corresponding to the designated tag information in the main storage unit 31. Thereafter, the numerical control device 1 performs a machining process on the workpiece using the machining information newly set in the main storage unit 31 (machining information to be restored), whereby a machining information restoration instruction input from the operator is performed. The machining process with the machining information corresponding to 46 is restored (reproduced).
