It should be noted that the operation management device 1 is mounted integrally with a housing (not shown) of the machine tool 4, and normally, a portion that is mounted with the NC device 16 is externally integrated with the NC device 16 in appearance. It is provided in. The NC device 16 and the operation management device 1 may be apparently separated.

Since the operation management device 1 for the machine tool 4 has the above-mentioned configuration, when the machine tool 4 is used for machining, the main controller 2 controls the system program memory 1
The operation status analysis program OAP is read from 1, and the operation status of the machine tool 4 is managed and controlled based on the operation status analysis program OAP.

That is, the main controller 2 requests the operator or the like to input the machining data in step S1 of the operating status analysis program OAP. In response to this, the operator receives various processing data DATA regarding processing to be performed by the machine tool 4 from the operation management device 1 via the keyboard 5, a storage medium reading device (not shown), a data input means such as an online communication line. Input as operating condition data to be managed by.

The machining data DATA includes a weekly work list of machining work to be performed by the machine tool 4, a product part number,

It also includes control values directly related to the machining time, such as the feed rate specified in the machining program to be executed, various cutting conditions such as override values, and the like.

In step S1, when the input of the machining data DATA is completed and stored in a predetermined memory in the operation management control section 7, the process goes to step S2, and the main control section 2 causes the machining execution control section 6 to operate. A machining start command is output to the NC device 16, and in response to this, the NC device 16 starts machining of an actual work.

When the processing is started in this way, step S3 is entered and the main control section 2 instructs the operation management control section 7 to
The NC device 16 and the machine tool controlled by the NC device 16 are instructed to record the actual operation status, and the operation management control unit 7 stores various processing data during processing in the memory (not shown) as actual operation data.

It instructs to analyze the management data MDT stored in the operation management data file ODF.

In response to this, the operation status analysis control section 9
The machining status analysis program MAP as a subroutine of step S6 is executed. Machining status analysis program MA
P enters step S7, the actual machining end (completion) time of the work shown in the management data MDT, and the machining data D input in step S1 prior to the machining start.
When the machining end (completion) scheduled times stored in the ATA are compared with each other and both are within a predetermined allowable time difference range, that is, the machining is substantially delayed between them. If there is no difference, it is determined that the machining has been performed normally, and the process goes from step S6 to step S8.
The message creation control unit 10 is instructed to create the corresponding message.

The message creation control unit 10 selects the message MSG to be generated from the message file 21 when it is determined in step S7 of the processing status analysis program MAP that the processing has been normally performed, and the message MSG is communicated. It is output to the control unit 12. The message file 21 stores various messages MSG for the analysis result of the machining situation performed by the machining situation analysis program MAP which is the subroutine of step S6, and depending on the content determined by the machining situation analysis program MAP. ,
The corresponding message MSG can be immediately selected from the message file 21.

When the corresponding message MSG is selected by the message creation control unit 10, the machining status analysis program MAP enters step S9 and the communication control unit 12

Is usually the manager of the machine tool (such as the company manager)
Since it is carried by, the administrator can immediately recognize the situation regarding the machining performed by the machine tool in real time even if the administrator is away from the machining site and is outside.

Message MSG for portable terminal 20
Is displayed on the display 20a of the mobile terminal 20 as shown in FIG. 4, for example.
Voice or other methods may be used.

In step S7 of the machining status analysis program MAP, the actual machining end (completion) time of the workpiece shown in the management data MDT and the machining data DATA input in step S1 prior to the machining start. If the machining end (completion) scheduled times stored in the two are compared, and both are not within the predetermined allowable time difference range, that is, if some delay occurs during actual machining, step S
10, the time difference TD1 between the planned machining end time and the actual machining end time is calculated and obtained, and the process goes to step S11.

In step S11, the actual processing disclosure time of the work shown in the management data MDT and the processing data DA input in step S1 prior to the start of processing.
The scheduled machining start times stored in TA are compared to determine whether the machining of the workpiece has started as scheduled.

The actual processing disclosure time of the work shown in the management data MDT and the step S prior to the start of processing.
If the processing start scheduled times input in 1 and stored in the processing data DATA are substantially the same, step S
12, the processing of the work is judged to have started as planned, and the message creation control unit 10 is instructed to selectively create the corresponding message MSG from the message file 21.

As for the step marked with "*" on the right shoulder of each step of the machining status analysis program MAP, the message MSG corresponding to the message described in the step is sent to the message creation control unit 10.
Is included in the operation. Hereinafter, with respect to each step marked with "*", description of the creation of the message MSG will be omitted.

Further, in step S11, the management data MD
The actual processing disclosure time of the work shown in T and the scheduled processing start time stored in the processing data DATA input in step S1 prior to the start of processing are substantially different from each other. When it is determined that the processing start has been delayed, step S13 is entered. In step S13,
The difference between the actual processing disclosure time of the workpiece and the scheduled processing start time stored in the processing data DATA is obtained as the time difference TD2.

Next, the machining status analysis program MAP
In step S14, the actual machining end (completion) time and the machining end (completion) scheduled time of the work immediately before machining the work are compared, and both are within a predetermined allowable time difference range, that is, When the processing is completed as scheduled, the process goes to step S15.

In step S15, the machining of the immediately preceding work is completed as planned, and the start of machining of the present work is delayed as shown in step S13. Therefore, the delay is set up during machining. It is determined that it took time to create the message MSG in step S8.

Further, in step S14, the actual machining end (completion) of the workpiece immediately before machining the workpiece.
The time is compared with the scheduled processing end (completion) time, and when both are not within the predetermined allowable time difference range, step S16 is entered, and the time difference in step S14, that is, the delay is
It is determined whether it is within 10 minutes.

If the time difference in step S14 is within 10 minutes, the time difference TD1 in step S10 is, for example, 10 minutes.
If it is more than a minute, it is determined in step S15 that the time difference TD1 in step S10 has occurred because the setup time is longer than the predetermined time, and the message MSG in step S8 is created.

Further, in step S16, step S14
When it is determined that the time difference, that is, the delay is 10 minutes or more, the process proceeds to step S17, and the time difference T of step S10.
D1 determines that this is caused by the delay in the machining of the workpiece before the machining of the workpiece, and creates the message MSG in step S8.

At the steps S12, S15 and S17, when the corresponding judgment about the delay is made, the machining status analysis program MAP executes the step S
18 and alarms for the NC system of the NC device 16 (for example, in the case of the present embodiment, alarm numbers 5 to 5).
23) is not generated, and if an alarm is generated, step S19 is entered and step S19 is executed.
It is determined that the delay of 10 is caused by the abnormality of the NC system, and the message MSG of step S8 is created. It should be noted that, in the determination of the delay in step S15 or step S17
Subsequent determination of delay may cause duplication, that is, there may be a delay in processing time due to multiple causes. In that case, the creation of the message MSG in step S8 is
It is generated for each judgment in each step and stored in an appropriate memory.

Next, the machining status analysis program MAP
In step S20, the alarm generation time of the NC system in step S19 and the machining stop time due to the alarm are acquired from the management data MDT, and when the message MSG is transmitted to the mobile terminal 20, which will be described later, the message MSG is added to the message MSG. Corresponding management data MDT is also mobile terminal 2
It is transmitted to 0.

In step S18, when the alarm of the NC device 16 has not occurred, and the processing status analysis program MAP which has finished the processing in step S20,
21 and enter an alarm (for example,
In the case of the present embodiment, it is determined whether or not the alarm number 24) is generated, and if an alarm is generated, the process proceeds to step S22, and it is determined that the delay of step S10 is caused by the mechanical load abnormality. Then, the message MSG of step S8 is created.

The machining status analysis program MAP enters step S23, acquires the alarm generation time of the mechanical load abnormality in step S22, and the machining stop time due to the alarm from the management data MDT, and the mobile terminal 2 described later.
When transmitting the message MSG to 0, the management data MDT corresponding to the message MSG is also transmitted to the mobile terminal 20.

In step S21, when the alarm of the mechanical load abnormality is not issued, and the processing status analysis program MAP which has finished the processing in step S23,
24, and an alarm relating to a program error (for example, alarm numbers 120 to 127 in this embodiment).
If no alarm has occurred, step S25 is entered. It is determined that the delay in step S10 is caused by a program error, and the message MSG in step S8 is created.

The machining status analysis program MAP enters step S26, acquires the time when the program error alarm is generated in step S25 and the machining stop time due to the alarm from the management data MDT, and sends it to the mobile terminal 20 which will be described later. When transmitting the message MSG, the management data MDT corresponding to the message MSG is also transmitted to the mobile terminal 20.

In step S24, if a program error alarm has not occurred, and if the machining status analysis program MAP that has completed the processing in step S26 enters step S27, it is determined whether or not an alarm regarding tool breakage has occurred. If it is determined that an alarm has occurred, step S28 is entered, and it is determined that the delay in step S10 is caused by tool breakage, and the message MSG in step S8 is created.

The machining status analysis program MAP enters step S29, and the time at which the tool breakage alarm is generated at step S28 and the machining stop time due to the alarm are set.
When the message MSG is acquired from the management data MDT and is transmitted to the mobile terminal 20, which will be described later, the message MS
The management data MDT corresponding to G is also transmitted to the mobile terminal 20.

In step S27, when the tool breakage alarm is not issued, and the machining status analysis program MAP which has finished the processing in step S29,
Then, it is judged whether or not an alarm due to a pressure drop such as air pressure or hydraulic pressure is generated, and if an alarm is generated, step S31 is entered, and the delay of step S10 is caused by the pressure drop. Judge, step S
8 message MSG is created.

The machining status analysis program MAP enters step S32, and determines the time of occurrence of the pressure drop alarm of step S31 and the machining stop time due to the alarm.
When the message MSG is acquired from the management data MDT and is transmitted to the mobile terminal 20, which will be described later, the message MS
The management data MDT corresponding to G is also transmitted to the mobile terminal 20.

In step S30, when the pressure drop alarm is not generated, and the machining status analysis program MAP which has finished the processing in step S32, enters into step S33 in FIG. 3 and the planned machining input by the machining data DATA is entered. It is determined whether or not more than the number of workpieces have been processed, and if it is determined that more than the planned number of workpieces have been processed, step S34 is entered.

In step S34, it is determined whether or not the operation in the manual mode has been performed during machining due to the occurrence of defective products. If not, the process proceeds to step S35, in which the number of products to be machined is larger than expected, that is, It is determined that the delay in step S10 has occurred due to the addition of an order, and the message MSG in step S8 is created.

If it is determined in step S34 that a defective product has occurred and therefore the operation in the manual mode has been performed during processing, the process proceeds to step S36, and the processing is delayed in step S10. Then, the message MSG of step S8 is created.

If it is not determined in step S33 that the workpiece has been machined more than the planned number of machining, or if the processing of step S35 and step S36 is completed, step S37 is entered and the actual machining is performed. Whether or not the override value such as the feed speed or the spindle rotational speed is lower than the specified value is determined by referring to the override value stored in the operation management data file ODF and used in the actual machining. Step S33
When it is determined that the override value is lower than the specified value, step S38 is entered, and it is determined whether the override value relating to the spindle rotational speed is low, and the override value relating to the spindle rotational speed is low. If it is determined that the load on the spindle is 1
It is determined whether the value exceeds 00 percent.

If it is determined that the load on the main spindle does not exceed 100%, then step S40 is entered and there is no reason to set the override low. Therefore, the delay in step S10 is delayed because of an override setting error. It is determined that the message MSG is created in step S8.

Further, in step S39, the load of the spindle is set to 1
If it is determined that the overload condition is exceeded by more than 00%, the spindle rotation speed is set improperly in the machining program and the spindle is overloaded. It is determined that the state has been avoided, and the improper cutting condition (peripheral speed) is set in the machining program in step S41.
It is determined that the delay of 0 has occurred, and the message MSG of step S8 is created.

If it is determined in step S38 that the value of the override relating to the spindle rotational speed is not low, or if the processing of steps S40 and S41 has ended, step S42 is entered and the override relating to the cutting feed speed is changed. It is determined whether the value is low, and if it is determined that the override value for cutting feed is low, step S43 is entered and it is determined whether the feed axis load exceeds 100%.

If it is determined that the feed axis load does not exceed 100%, there is no reason to go to step S44 and set the override low. Therefore, there is a delay in step S10 due to a mistake in setting the override. It is determined that the message MSG is created in step S8.

If it is determined in step S43 that the load on the feed axis exceeds 100% and is in an overloaded state, the feed rate setting in the machining program is inappropriate and In the overload state, it is determined that the override value is lowered to avoid the overload state, and in step S45, inappropriate cutting conditions (feed)
Since it was set in the machining program, it is determined that the delay in step S10 has occurred, and the message MSG in step S8 is created.

If it is determined in step S42 that the override value for the feed axis is not low, or if the processing in steps S44 and S45 is completed, step S46 is entered, and the override value for the rapid feed speed is determined. If it is determined that it is not low, and the override value for fast-forward is determined to be low,
In step S47, it is determined that the delay in step S10 has occurred because the override of fast-forward is low,
The message MSG of step S8 is created.

Next, the main control unit 2 enters step S48 of the operation status analysis program OAP, and judges whether or not time has been generated in the manual mode during machining from the operation mode data in the operation management data file ODF. When it is determined that the time in the manual mode has occurred, step S49 is entered and the time in the manual mode is acquired.

Next, in step S50, it is determined whether or not the tool data has been changed during machining. If it is determined that the tool data has been changed, step S51 is entered and the tool reaches the end of its life during machining. It is determined whether or not a tool life alarm for notifying the tool life has occurred. If it is determined that the tool life alarm notifying the tool life has not occurred,
In step S52, the tool data is changed because it is determined that the delay in step S10 has occurred because the tool correction operation is performed by manually moving the tool and the tool correction value is input at that time. Message MSG in step S8
To create.

If it is determined in step S51 that the tool has reached the end of its service life during machining and a tool life alarm for notifying the tool life has occurred, step S53 is entered to perform tool replacement due to the tool life alarm. Then, it is determined that the delay of step S10 has occurred, and the message MSG of step S8 is created.

If it is determined in step S49 that the tool data has not been changed, or if the processing in steps S52 and S53 has ended, step S49 is performed.
54, it is determined whether or not a maintenance alarm for instructing the maintenance of the machine has occurred, and if the maintenance alarm has occurred, step S55
Then, it is determined that the delay in step S10 has occurred due to the maintenance work, and the message MSG in step S8 is created.

After processing step S48, step S54 and step S55, the operating condition analysis program OA
P enters step S56, determines whether or not an emergency stop of the machine has occurred, and if it is determined that an emergency stop has occurred, P enters step S57 and manages the time of the emergency stop. It is obtained from the data file ODF, and it is determined in step S59 that the delay in step S10 has occurred due to the emergency stop, and the message MSG in step S8 is created.

After processing step S56 and step S59, the operating condition analysis program OAP
In step 60, it is determined whether or not the cause of the delay time in step S10 can be identified by the above process. If it cannot be identified, step S61 is entered and the machining time of the machining data DATA input in step S1 is determined. It is determined that the estimation of is not accurate, and the processing time has been estimated too short from this place, and the message MSG of step S8 is created.

Thus, in step S6 of FIG. 2, the machining status analysis is performed by the machining status analysis program MAP,
With respect to the machining performed in step S2, the cause of the machining exceeding the estimated machining estimated time is investigated, and the corresponding message MSG is created by the message creation control unit 10, and as described above, the communication control unit 12 Transmits the message MSG to the mobile terminal 20 via the communication network 19.

As shown in FIG. 4, the portable terminal 20 displays on the display 20a various messages MSG created by the message creation control unit 10 and related to the cause of the processing delay determined by the processing status analysis program MAP. At the same time, since the management data MDT indicating the operating status of the machine tool during the related actual machining is displayed, the manager can accurately grasp the current operating status of the machine tool in real time.
