(Log recording process)
FIG. 6 is a flowchart illustrating an example of the operation of the log recording process according to the first embodiment. FIG. 7 is a diagram illustrating an example of a dialog displayed as a pop-up in the first embodiment. FIG. 8 is a diagram illustrating an example of a log at the time of tool adjustment according to the first embodiment. FIG. 9 is a diagram illustrating an example of a log at the time of tool replacement according to the first embodiment. The log recording process of the diagnostic apparatus 100 according to the present embodiment will be described with reference to FIGS.

<Step S11>
The numerical control unit 201 of the processing machine 200 causes the drive control unit 203 to stop the processing operation by the drive unit 204. The numerical control unit 201 transmits context information indicating that the machining operation by the driving unit 204 has been stopped to the first reception unit 101 a of the diagnostic apparatus 100 via the communication control unit 202.

  The machining information acquisition unit 102 of the diagnostic apparatus 100 acquires context information that is received by the first receiving unit 101a and indicates that the machining operation by the specific tool has stopped. The log writing unit 112 records the content of the context information acquired by the processing information acquisition unit 102 as a log in time series in the storage unit 108. For example, when the machining by the tool “drill 1” is stopped, the log writing unit 112 associates the date and time when the machining is stopped with the fact that the machining by the “drill 1” is stopped, as shown in FIG. , And is recorded in the storage unit 108 as a log (an example of a second log).

  Then, the process proceeds to step S12.

<Step S12>
When the operator confirms that the machining operation by the processing machine 200 has stopped, the operator adjusts the position of the tool in the drive unit 204 or replaces the tool. Then, the process proceeds to step S13.

<Step S13>
After adjusting or exchanging the tool, the operator activates the processing machine 200 and restarts the processing operation. Then, the process proceeds to step S14.

<Step S14>
The detection unit 211 detects a physical quantity emitted by the tool of the drive unit 204 that has resumed the machining operation, and outputs the detected physical quantity information as detection information (sensor data) to the second reception unit 101b of the diagnostic apparatus 100. The operation determination unit 106 determines that the machining operation has been resumed based on the context information received by the first reception unit 101a. The measurement unit 104 determines the degree of wear of the tool of the processing machine 200 based on the detection information received by the second reception unit 101b after the operation determination unit 106 determines that the processing operation of the processing machine 200 has been resumed. Measure. The wear determination unit 107 determines how much the wear degree has changed. When the degree of wear has decreased by a predetermined threshold value or more (step S14: “decrease”), the process proceeds to step S15, and when the degree of wear is 0 (step S14: “0”), the process proceeds to step S16. When an unexpected value such as an increase in wear level is indicated (step S14: “other than that”), the process proceeds to step S17.

<Step S15>
When the wear determination unit 107 determines that the degree of wear has decreased by a predetermined threshold or more, the pop-up display control unit 110b estimates that the tool has been adjusted, and an adjustment confirmation dialog 501 (first dialog) as shown in FIG. Is displayed on the display unit 111 in a pop-up manner. Then, the process proceeds to step S18.

<Step S16>
When the wear determination unit 107 determines that the wear degree is 0, the pop-up display control unit 110b estimates that the tool has been replaced, and the replacement confirmation dialog 502 (second dialog) as shown in FIG. Is displayed on the display unit 111 in a pop-up manner. Then, the process proceeds to step S18.

<Step S17>
When the wear determination unit 107 indicates an unexpected wear value, the pop-up display control unit 110b displays, for example, a dialog indicating that the wear level is abnormal as a process when the wear level is abnormal. 111 is popped up. This ends the log recording process.

  When the wear determination unit 107 indicates an unexpected value, the log writing unit 112 may write a log indicating that the wear level is abnormal in the storage unit 108.

<Step S18>
The operator confirms a dialog (adjustment confirmation dialog 501 or replacement confirmation dialog 502) displayed on the display unit 111, and performs a desired operation input via the input unit 109. Then, the process proceeds to step S19.

<Step S19>
For example, as shown in FIG. 7, when the adjustment confirmation dialog 501 is displayed on the display unit 111 and the operator presses the “Yes” button via the input unit 109, the log writing unit 112. As shown in FIG. 8, the date and time when the tool is adjusted is associated with “☆ adjustment” indicating that the tool has been adjusted, and is recorded in the storage unit 108 as a log (first log). Then, the pop-up display control unit 110b closes the adjustment confirmation dialog 501. Note that “☆” indicates a log relating to tool adjustment or replacement.

  On the other hand, when the adjustment confirmation dialog 501 is displayed on the display unit 111 and the operator presses the “No” button via the input unit 109, the pop-up display control unit 110 b displays the dialog of the display unit 111. Is changed from the adjustment confirmation dialog 501 to the replacement confirmation dialog 502. If the replacement confirmation dialog 502 is displayed on the display unit 111 and the operator presses the “Yes” button via the input unit 109 because the tool has been replaced rather than adjusted, the log As shown in FIG. 9, the writing unit 112 associates the date and time of tool replacement with “☆ replacement” indicating that the tool has been replaced, and records it in the storage unit 108 as a log (first log). Then, the pop-up display control unit 110b closes the replacement confirmation dialog 502. On the other hand, when the replacement confirmation dialog 502 is displayed on the display unit 111 and the operator presses the “No” button via the input unit 109, the log writing unit 112 does not record the log. The pop-up display control unit 110b closes the replacement confirmation dialog 502.

  As shown in FIG. 7, when the replacement confirmation dialog 502 is displayed on the display unit 111 and the operator presses the “Yes” button via the input unit 109, the log writing unit 112. As shown in FIG. 9, the date and time when the tool is replaced is associated with “☆ replacement” indicating that the tool has been replaced, and is recorded in the storage unit 108 as a log (first log). Then, the pop-up display control unit 110b closes the replacement confirmation dialog 502. On the other hand, when the replacement confirmation dialog 502 is displayed on the display unit 111 and the operator presses the “No” button via the input unit 109, the log writing unit 112 does not record the log. The pop-up display control unit 110b closes the replacement confirmation dialog 502.

  This ends the log recording process.

  In the description of step S19 described above, when the “No” button is pressed in the adjustment confirmation dialog 501, the transition to the replacement confirmation dialog 502 is assumed. However, the present invention is not limited to this. For example, when the “No” button is pressed in the adjustment confirmation dialog 501, the transition confirmation dialog 502 may not be displayed, and the log may not be recorded. Alternatively, when the “No” button is transitioned while the replacement confirmation dialog 502 is displayed, the adjustment confirmation dialog 501 may be transitioned to.

  The log recording process by the diagnostic apparatus 100 is performed according to the flow of steps S11 to S19.

  As described in steps S13 to S16 above, when the processing operation by the processing machine 200 is resumed after the operator adjusts or replaces the tool, the change is based on the change in the degree of wear measured by the measuring unit 104. The adjustment confirmation dialog 501 or the replacement confirmation dialog 502 is displayed, but the present invention is not limited to this. That is, after the operator adjusts or replaces the tool, the measuring unit 104 can measure the wear level even if the machining operation by the processing machine 200 is not resumed, and the wear determination unit 107 determines the change in the wear level. If the configuration can perform this, the adjustment confirmation dialog 501 or the replacement confirmation dialog 502 may be displayed before the machining operation is resumed.

  As described above, when the measured wear degree satisfies the predetermined condition when the processing is resumed after the processing of the processing machine 200 is stopped, a dialog for confirming whether the tool has been adjusted or replaced is displayed in a pop-up, which is easy for the operator. It is recorded as a log that the tool has been adjusted or replaced by simple operation input. This means that there is no need to record manually when adjusting or changing the tool, and that the tool has been adjusted or replaced by performing a simple operation on the dialog that pops up for confirmation. Logs can be recorded easily.

In the first embodiment described above, a change in the degree of wear measured after resuming the machining is determined, and based on the determination result, it is determined whether the adjustment confirmation dialog is popped up or the replacement confirmation dialog is popped up. It was working. In this modification, after the machining is resumed, the pop-up display control unit 110b does not estimate whether the tool has been adjusted or replaced, and if the wear degree has changed to a predetermined level, the pop-up display control unit 110b An operation for displaying a dialog for directly determining whether the adjustment or replacement is performed will be described.

  FIG. 10 is a diagram illustrating an example of a dialog displayed as a pop-up in the modification of the first embodiment. With reference to FIG. 10, a dialog that pops up when the degree of wear decreases due to adjustment or replacement of the tool in this modification will be described.

  In the present modification, in step S14 of FIG. 6 described above, when the wear determination unit 107 determines, for example, that the degree of wear has decreased by a predetermined threshold or more (an example of a predetermined condition), the pop-up display control unit 110b is Then, it is assumed that the tool has been adjusted or replaced, and an adjustment / replacement confirmation dialog 503 (an example of a third dialog) as shown in FIG.

  In step S <b> 18 shown in FIG. 6 described above, the operator confirms the adjustment / replacement confirmation dialog 503 displayed on the display unit 111 and performs a desired operation input via the input unit 109.

  In step S19 shown in FIG. 6 described above, for example, as shown in FIG. 10, the adjustment / replacement confirmation dialog 503 is displayed, and the operator presses the “Adjust” button via the input unit 109. In this case, as shown in FIG. 8 described above, the log writing unit 112 associates the date and time when the tool is adjusted with “☆ adjustment” indicating that the tool has been adjusted, and records it in the storage unit 108 as a log.

  When the adjustment / replacement confirmation dialog 503 is displayed on the display unit 111 and the operator presses the “replace” button via the input unit 109, the log writing unit 112 displays the above-described figure. As shown in FIG. 9, the date and time when the tool is changed and “☆ change” indicating that the tool is changed are associated with each other and recorded in the storage unit 108 as a log.

  Further, when the adjustment / replacement confirmation dialog 503 is displayed on the display unit 111 and the operator presses the “No” button via the input unit 109, the log writing unit 112 records the log. Instead, the pop-up display control unit 110b closes the adjustment / replacement confirmation dialog 503.

  As described above, after the tool is adjusted or replaced by the operator, when the processing machine 200 is activated and the processing operation is resumed, the wear determination unit 107 determines that the wear degree is, for example, a predetermined threshold value. When it is determined that the level has been lowered, an adjustment / replacement confirmation dialog 503 is displayed, and it is assumed that the operator directly confirms whether the adjustment or replacement is performed. This also means that there is no need to record manually when adjusting or replacing the tool, and that the tool has been adjusted or replaced by performing a simple operation on the dialog that pops up for confirmation. Can be easily recorded.

  For example, if the wear determination unit 107 determines that the wear level has decreased by a predetermined threshold or more, the pop-up display control unit 110b estimates that the tool has been adjusted or replaced, and displays an adjustment / replacement confirmation dialog 503. Although pop-up display is performed on the display unit 111, the present invention is not limited to this. For example, when the wear level is increased by the wear determination unit 107, or when the wear level is lower than a predetermined threshold, the pop-up display control unit 110b pops up the adjustment / replacement confirmation dialog 503 on the display unit 111. It is good. As a result, even if the tool is adjusted or replaced, the tool is adjusted or replaced even if there is no expected change in the degree of wear due to some malfunction (for example, a malfunction of the work or a malfunction of the detection unit 211). This can be recorded as a log.

[Second Embodiment]
The diagnostic system according to the second embodiment will be described focusing on differences from the diagnostic system according to the first embodiment. In the first embodiment, the degree of wear of the tool is measured regardless of the number of machining operations, and the adjustment confirmation dialog or the exchange confirmation dialog is displayed when the degree of wear changes before and after the machining operation. In this embodiment, initial learning for learning the relationship between the degree of wear and the number of machining is performed, the degree of wear is ranked in a predetermined stage, and when the rank changes before and after the machining operation, an adjustment confirmation dialog or The operation for displaying the replacement confirmation dialog will be described. The overall configuration of the diagnostic system and the hardware configuration of the processing machine and the diagnostic device are the same as those described in the first embodiment.

(Configuration and operation of functional block of diagnostic system)
FIG. 11 is a diagram illustrating an example of a functional block configuration of the diagnostic system according to the second embodiment. FIG. 12 is a graph showing an example of the relationship between the number of machining operations and the degree of wear. With reference to FIGS. 11 and 12, the configuration and operation of the functional blocks of the diagnostic system according to the present embodiment will be described. The configuration and operation of the functional blocks of the processing machine 200 are the same as the contents described in the first embodiment.

  As illustrated in FIG. 11, the diagnostic device 100a includes a communication control unit 101, a processing information acquisition unit 102 (second acquisition unit), a processing times acquisition unit 103 (third acquisition unit), a measurement unit 104, and a popup. Display setting unit 105, operation determination unit 106 (second determination unit), wear determination unit 107 (first determination unit, determination unit), storage unit 108, input unit 109, display control unit 110, display Unit 111, log writing unit 112 (writing unit), and wear rank setting unit 113 (second setting unit). In addition, the communication control unit 101, the processing information acquisition unit 102, the processing number acquisition unit 103, the measurement unit 104, the operation determination unit 106, the wear determination unit 107, the input unit 109, the pop-up display control unit 110b, the display unit 111, and a log document The operation of the insertion unit 112 is the same as that described in the first embodiment.

  The wear rank setting unit 113 performs initial learning for learning the relationship between the number of times of machining and the degree of wear based on the number of times of machining acquired by the number of times of machining acquiring unit 103 and the degree of wear of the tool measured by the measuring unit 104. It is a functional unit that performs setting for classifying the wear degree into predetermined stages. In the processing machine 200, when the tool of the drive unit 204 is replaced with a new type or the like, the relationship between the number of times the tool is processed and the degree of wear is unknown. Therefore, after the tool is changed, the machining operation is repeated up to the number of times that the tool is regarded as the limit of the number of machining operations (hereinafter sometimes referred to as “the upper limit of the number of times”), and as shown in FIG. It is desirable to perform a process of learning the relationship between the degree of wear and the degree of wear. Here, the upper limit of the number of times may be obtained based on, for example, the relationship between the characteristics of the material of the tool and the degree of wear of other tools. Alternatively, the initial learning may be performed with the number of times until the tool is damaged by the machining operation as the upper limit of the number of times. However, in the event of tool breakage, it is safe for workers, etc., assuming that a part of the broken tool is scattered, or that the jig holding the tool is broken or misaligned. It is assumed that it is sufficiently secured.

  As a result of the initial learning, the wear rank setting unit 113 obtains the relationship between the number of machining operations and the wear degree as shown in FIG. 12, for example, and determines the wear degree at a predetermined stage (“wear rank 1” to “wear” in FIG. 12). Rank 3)). In addition, although the graph which shows the relationship between the frequency | count of a process shown in FIG. 12 and an abrasion degree has shown typically that the abrasion degree is rising linearly, it is not limited to this, The physical characteristic of a tool The shape of the graph as a result of the initial learning differs depending on the shape and the like. In FIG. 12, the rank division is divided into three stages and the rank widths are equally spaced. However, the present invention is not limited to this, and the number of rank divisions and the rank widths may be set freely.

  The wear rank setting unit 113 is realized, for example, by a program that runs on the CPU 61 shown in FIG.

  The storage unit 108 stores various information necessary for the diagnostic function of the diagnostic device 100a, the content of initial learning performed by the wear rank setting unit 113, the content of predetermined rank classification of the set wear degree, and the processing machine 200. It is a functional part which memorizes the log etc. which show the record of the processing state, adjustment, exchange, etc. The storage unit 108 is realized by, for example, the auxiliary storage device 68 illustrated in FIG.

  The pop-up display setting unit 105 is a functional unit that sets under what conditions the pop-up display of the adjustment confirmation dialog or the replacement confirmation dialog is displayed. For example, the pop-up display setting unit 105 may set conditions for pop-up display based on an operation input by the operator via the input unit 109. For example, after the machining operation of the processing machine 200 is stopped and the tool is adjusted or replaced, the pop-up display setting unit 105 starts the machining operation next, and the wear determination unit 107 transitions to a wear rank with a low degree of wear (for example, , “Adjustment rank 3” to “wear rank 2”), an adjustment confirmation dialog pops up to change to the wear rank with the lowest degree of wear (for example, “wear rank 3” to “wear rank 1”). In the case of transition), a condition for popping up an exchange confirmation dialog may be set. The pop-up display setting unit 105 is realized, for example, by a program that runs on the CPU 61 shown in FIG.

  The wear display control unit 110a of the display control unit 110 is, for example, based on the relationship between the degree of wear of the tool measured by the measurement unit 104 and the number of machining operations initially learned by the wear rank setting unit 113 and the degree of wear. This is a functional unit that causes the display unit 111 to display at least one of the wear rank of the tool and the like. Note that the wear display control unit 110a may display on the display unit 111, for example, a warning or a tool replacement when the difference between the number of machining operations and the upper limit value of the number of operations is equal to or less than a predetermined value. Good.

  In addition, the communication control unit 101, the processing information acquisition unit 102, the processing number acquisition unit 103, the measurement unit 104, the pop-up display setting unit 105, the operation determination unit 106, the wear determination unit 107, the display control unit 110, and the log document illustrated in FIG. The insertion unit 112 and the wear rank setting unit 113 may cause the CPU 61 shown in FIG. 3 to execute a program as described above, that is, may be realized by software, or may be realized by hardware such as an IC. However, software and hardware may be used in combination.

  Moreover, each function part of the diagnostic apparatus 100a shown in FIG. 11 has shown the function notionally, and is not limited to such a structure. For example, a plurality of functional units illustrated as independent functional units in FIG. 11 may be configured as one functional unit. On the other hand, the function of one functional unit in FIG. 11 may be divided into a plurality of functions and configured as a plurality of functional units.

  As described above, initial learning for learning the relationship between the degree of wear and the number of machining is performed, the degree of wear is ranked in a predetermined stage, and an adjustment confirmation dialog or based on the change of the wear rank before and after the machining operation An exchange confirmation dialog is displayed. Thus, the current wear rank can be grasped, and the next tool adjustment or replacement time can be easily grasped from the relationship with the current number of machining operations.

The operations of the unit 110a and the display unit 111 are the same as those described in the first embodiment.

  When the operation mode is set to the manual mode by the mode setting unit 114, the pop-up display control unit 110b of the display control unit 110 performs an adjustment confirmation dialog or a replacement confirmation according to the pop-up display conditions set by the pop-up display setting unit 105. This is a functional unit that displays a dialog on the display unit 111.

  When the operation mode is set to the manual mode by the mode setting unit 114, the log writing unit 112 logs that the tool has been adjusted or replaced according to the content input through the adjustment confirmation dialog or the replacement confirmation dialog. As a functional unit that writes (records) in the storage unit 108. Further, when the operation mode is set to the automatic mode by the mode setting unit 114, the log writing unit 112 adjusts or replaces the tool according to the change in the degree of wear of the tool determined by the wear determination unit 107. The fact that the tool has been adjusted or replaced is written (recorded) in the storage unit 108 as a log. The log writing unit 112 is realized by, for example, a program that operates on the CPU 61 illustrated in FIG.

  The mode setting unit 114 is a functional unit that sets the operation mode of the processing machine 200 to a manual mode or an automatic mode. The mode setting unit 114 sets an operation mode in accordance with, for example, an operation performed by the operator via the input unit 109.

On the other hand, the function of one functional unit in FIG. 13 may be divided into a plurality of units and configured as a plurality of functional units.

(Log recording process)
FIG. 14 is a flowchart illustrating an example of an operation of log recording processing according to the third embodiment. The log recording process of the diagnostic device 100b according to the present embodiment will be described with reference to FIG.

<Steps S31 to S34>
The processes in steps S31 to S34 are the same as the processes in steps S11 to S14 shown in FIG. If the degree of wear has decreased by a predetermined threshold value or more (step S34: “decrease”), the process proceeds to step S35, and if the degree of wear is 0 (step S34: “0”), the process proceeds to step S37. If an unexpected value such as an increase in the degree of wear and the like is shown (step S34: “other than that”), the process proceeds to step S40.

<Step S35>
When the operation mode is set to the manual mode by the mode setting unit 114 (step S35: manual), the process proceeds to step S36, and when the automatic mode is set (step S35: automatic), the process proceeds to step S41.

<Step S36>
When the wear determination unit 107 determines that the degree of wear has decreased by a predetermined threshold or more, the pop-up display control unit 110b estimates that the tool has been adjusted, and displays an adjustment confirmation dialog 501 as shown in FIG. To pop up. Then, the process proceeds to step S39.

<Step S37>
When the operation mode is set to the manual mode by the mode setting unit 114 (step S37: manual), the process proceeds to step S38. When the operation mode is set to the automatic mode (step S37: automatic), the process proceeds to step S41.

<Step S38>
When the wear determination unit 107 determines that the degree of wear is 0, the pop-up display control unit 110b assumes that the tool has been replaced, and displays a replacement confirmation dialog 502 as shown in FIG. To pop up. Then, the process proceeds to step S39.

<Steps S39 and S40>
Steps S39 and S40 are the same as steps S18 and S17 shown in FIG. 6, respectively.

<Step S41>
When the operation mode is the manual mode, the log writing unit 112 and the pop-up display control unit 110b perform the same process as the process of step S19 illustrated in FIG.

  On the other hand, when the operation mode is the automatic mode, the log writing unit 112 estimates that the tool has been adjusted when the wear determination unit 107 determines that the wear level has decreased by a predetermined threshold or more in step S34, and the tool The date and time when the adjustment is made and the adjustment “☆ adjustment” are associated with each other and recorded in the storage unit 108 as a log (see FIG. 8). In addition, when the wear determination unit 107 determines that the degree of wear is 0 in step S34, the log writing unit 112 estimates that the tool has been replaced, and has replaced the date and time when the tool was replaced. The message “☆ exchange” is associated with the message and recorded in the storage unit 108 as a log (see FIG. 9).

  This ends the log recording process.

  The log recording process by the diagnostic device 100b is performed by the flow of steps S31 to S41 described above.

  As described above, in the present embodiment, the operation mode can be switched between the manual mode and the automatic mode, and in the automatic mode, the pop-up display and the operation input work by the operator are skipped and recorded in the log. This means that there is no need to record manually when adjusting or changing the tool, and in automatic mode, there is no need to perform simple operations on the pop-up dialog, and that the tool has been adjusted or replaced. Logs can be recorded easily.

[Fourth Embodiment]
The diagnosis system according to the fourth embodiment will be described focusing on differences from the diagnosis system according to the first embodiment. In the first embodiment, after processing the machine 200 is stopped and the tool is adjusted or exchanged, only the fact that the tool has been adjusted or exchanged is recorded in the log by a simple operation on the displayed dialog. . However, instead of recording only the adjustment or replacement of the tool, a comment such as the manner in which the adjustment was performed or the reason other than that the degree of wear increased for the purpose of adjustment or replacement is further recorded. This is often more useful from the viewpoint of maintenance of the processing machine 200. In the present embodiment, when the processing machine 200 is stopped and the tool is adjusted or exchanged, not only that the tool is adjusted or exchanged, but also an operation in which a comment can be added and recorded accordingly. explain. Note that the overall configuration of the diagnostic system, the hardware configuration of the processing machine and the diagnostic device, and the configuration of the functional blocks of the diagnostic system are the same as those described in the first embodiment.

(Operation of pop-up display)
FIG. 15 is a diagram for explaining at what timing pop-up display is performed in the fourth embodiment. The outline of the pop-up display operation of the present embodiment will be described with reference to FIG.

  The pop-up display setting unit 105 sets under what conditions the pop-up display of the adjustment confirmation dialog or the replacement confirmation dialog is performed as described above. In the present embodiment, for example, as shown in FIG. 15, the pop-up display setting unit 105 stops the machining operation of the processing machine 200 and adjusts or replaces the tool (“blade” in FIG. 15). When the operation is started and the wear determination unit 107 determines that the degree of wear is lower than a predetermined threshold value, an adjustment confirmation dialog is popped up, and a comment dialog associated therewith is displayed to display a memo (comment). It is assumed that a condition for enabling input is set. Further, as shown in FIG. 15, when the wear determination unit 107 determines that the degree of wear is 0, the pop-up display setting unit 105 displays a replacement confirmation dialog in a pop-up, and further includes a comment dialog associated therewith. It is assumed that a condition is set so that a memo (comment) can be input by displaying.

  The pop-up display control unit 110b causes the display unit 111 to display an adjustment confirmation dialog, an exchange confirmation dialog, and a comment dialog according to the pop-up display conditions set by the pop-up display setting unit 105.

(Log recording process)
FIG. 16 is a flowchart illustrating an example of an operation of log recording processing according to the fourth embodiment. FIG. 17 is a diagram illustrating an example of a dialog displayed as a pop-up in the fourth embodiment. FIG. 18 is a diagram illustrating an example of a log during tool adjustment according to the fourth embodiment. FIG. 19 is a diagram illustrating an example of a log at the time of tool change according to the fourth embodiment. The log recording process of the diagnostic apparatus 100 according to the present embodiment will be described with reference to FIGS.

<Steps S51 to S54>
The processes in steps S51 to S54 are the same as the processes in steps S11 to S14 shown in FIG. If the degree of wear has decreased by a predetermined threshold value or more (step S54: “decrease”), the process proceeds to step S55. If the degree of wear is 0 (step S54: “0”), the process proceeds to step S56. If an unexpected value such as an increase in the degree of wear is indicated (step S54: “other than that”), the process proceeds to step S57.

<Step S55>
When the wear determination unit 107 determines that the degree of wear has decreased by a predetermined threshold or more, the pop-up display control unit 110b estimates that the tool has been adjusted, and displays an adjustment confirmation dialog 501 as shown in FIG. To pop up. Then, control goes to a step S58.

<Step S56>
When the wear determination unit 107 determines that the degree of wear is 0, the pop-up display control unit 110b estimates that the tool has been replaced, and displays a replacement confirmation dialog 502 as shown in FIG. To pop up. Then, control goes to a step S58.

<Step S57>
The process of step S57 is the same as that of step S17 shown in FIG.

<Step S58>
The operator confirms a dialog (adjustment confirmation dialog 501 or replacement confirmation dialog 502) displayed on the display unit 111, and performs a desired operation input via the input unit 109. Then, the process proceeds to step S59.

<Step S59>
For example, as shown in FIG. 17, when the adjustment confirmation dialog 501 is displayed on the display unit 111 and the operator presses the “Yes” button via the input unit 109, the log writing unit 112. As shown in FIG. 18, the date and time when the tool is adjusted is associated with “☆ adjustment” indicating that the tool has been adjusted, and is recorded in the storage unit 108 as a log. Then, the pop-up display control unit 110b changes the display of the dialog on the display unit 111 from the adjustment confirmation dialog 501 to the comment dialog 511. Note that “☆” indicates a log relating to tool adjustment or replacement.

  On the other hand, when the adjustment confirmation dialog 501 is displayed on the display unit 111 and the operator presses the “No” button via the input unit 109, the pop-up display control unit 110 b displays the dialog of the display unit 111. Is changed from the adjustment confirmation dialog 501 to the replacement confirmation dialog 502. If the replacement confirmation dialog 502 is displayed on the display unit 111 and the operator presses the “Yes” button via the input unit 109 because the tool has been replaced rather than adjusted, the log As illustrated in FIG. 19, the writing unit 112 associates the date and time when the tool is replaced with “☆ change” indicating that the tool has been replaced, and records the result as a log in the storage unit 108. Then, the pop-up display control unit 110b changes the display of the dialog on the display unit 111 from the replacement confirmation dialog 502 to the comment dialog 511. On the other hand, when the replacement confirmation dialog 502 is displayed on the display unit 111 and the operator presses the “No” button via the input unit 109, the log writing unit 112 does not record the log. The pop-up display control unit 110b changes the display of the dialog on the display unit 111 from the replacement confirmation dialog 502 to the comment dialog 512.

  As shown in FIG. 17, when the replacement confirmation dialog 502 is displayed on the display unit 111 and the operator presses the “Yes” button via the input unit 109, the log writing unit 112. As shown in FIG. 19, the date and time when the tool is changed is associated with “☆ change” indicating that the tool has been changed, and is recorded in the storage unit 108 as a log. Then, the pop-up display control unit 110b changes the display of the dialog on the display unit 111 from the replacement confirmation dialog 502 to the comment dialog 511. On the other hand, when the replacement confirmation dialog 502 is displayed on the display unit 111 and the operator presses the “No” button via the input unit 109, the log writing unit 112 does not record the log. The pop-up display control unit 110b changes the display of the dialog on the display unit 111 from the replacement confirmation dialog 502 to the comment dialog 512.

  Then, the process proceeds to step S60.

<Step S60>
As shown in FIG. 17, when the comment dialog 511 or the comment dialog 512 is displayed on the display unit 111, the worker inputs a comment for tool adjustment or replacement via the input unit 109. Then, the process proceeds to step S61.

<Step S61>
As shown in FIG. 17, when the comment dialog 511 is displayed on the display unit 111 and the operator presses the “OK” button via the input unit 109, the log writing unit 112 As shown in FIG. 18 and FIG. 19, the date and time when the tool is adjusted or replaced, the fact that the tool has been adjusted or replaced, and the input comment regarding the adjustment or replacement are associated with each other and recorded in the storage unit 108 as a log. For example, the example of FIG. 18 indicates that a comment “☆ Adjust depth and resume processing” is recorded as a log in association with the adjustment. Further, in the example of FIG. 19, it is shown that the comment “☆ blade was missing and replaced” is recorded as a log in association with the replacement. Then, the pop-up display control unit 110b closes the comment dialog 511.

  On the other hand, when the comment dialog 511 is displayed on the display unit 111 and the operator presses the “cancel” button via the input unit 109, the log writing unit 112 records the comment log. First, the pop-up display control unit 110b closes the comment dialog 511.

  Also, as shown in FIG. 17, when the comment dialog 512 is displayed on the display unit 111 and the operator presses the “OK” button via the input unit 109, the log writing unit 112 The date and time when the tool is adjusted or exchanged, and the fact that the tool has been adjusted or exchanged are associated with the comment related to the work other than the entered adjustment or exchange work, and recorded in the storage unit 108 as a log. Then, the pop-up display control unit 110b closes the comment dialog 512.

  On the other hand, when the comment dialog 512 is displayed on the display unit 111 and the operator presses the “cancel” button via the input unit 109, the log writing unit 112 records the comment log. First, the pop-up display control unit 110b closes the comment dialog 512.

  This ends the log recording process. The log recording process by the diagnostic device 100 is performed by the flow of steps S51 to S61 described above.

  As described above, in this embodiment, when the processing machine 200 is stopped and the tool is adjusted or replaced, not only the tool is adjusted or replaced, but also a comment is added and recorded accordingly. It is supposed to be possible. As a result, in addition to the effects of the first embodiment, the degree of wear is increased for the purpose of adjustment or replacement, not just the adjustment or replacement of the tool.
