34 is initialized.

Thereafter, when the power of the machine tool is turned on, or in the case of continuous operation, at the end of machining near the date change time, the log file 141a of the temporary file is converted and recorded on the fixed disk device 14 as a log file 141b for each day. At this time, only the log data of a specific date from the temporary log file 141a is moved to the log file 141b for each day. The log file 141b for each day contains date data in the file name, and by specifying a desired date, the log file on that date can be accessed.

The contents of the log file 141 are displayed on the display unit 1 by the display control program 133 in accordance with the instruction of the operator.

The record is a fixed length (for example, 100 bytes) data separated from each other by a line feed.
One record includes a section indicating the type of log data, a date on which the recording was performed, a time when the recording was performed, and various information indicating an operation state according to the following sections. These pieces of information are recorded as fixed-length fields each having a predetermined data length, and the fields are separated by delimiters (for example, commas).

The record of the category 0 indicates that the record is information on the operation of the machine tool. The records in section 1 relate to alarms, the records in section 2 relate to tool information, and the records in section 3 relate to measurement information. For example, the record of the log data of the section 0 includes the section, the date, the time, the activated NC.

FIG. 3 is a flowchart showing a process of recording log data of a machine tool. The CPU 10 executes the log recording program 131 and performs processing according to the flowchart of FIG. First, in process 101, the timer 18 is reset, and preparations are made to acquire the operating state of the machine tool at predetermined time intervals (for example, every 5 seconds). Next, in a calling process 102, a log storage subroutine is called, and log data is stored in a log area 134 at predetermined time intervals or when an event occurs. Next, in decision 103, it is determined whether or not the machine tool is being machined. If the machine is being machined, the process returns to the calling process 102;

In the process 104, the log data stored in the log area 134 is additionally recorded in the fixed disk device 14 as a temporary log file 141a. At this time, if the power of the machine tool is turned on or the date is changed, the temporary log file 141a is converted and recorded on the fixed disk device 14 as the log file 141b for each day. Then, the log area 134 is initialized in the process 105, and the process returns to the calling process 102, and the above process is repeated. Log area 13
As No. 4, a capacity sufficient to store all log data generated during processing of the machine tool is secured. As described above, during the processing of the machine tool, the log data is recorded in the RAM capable of high-speed processing, so that the recording of the log data does not affect the processing.

FIG. 4 is a flowchart showing the processing of the log storage subroutine called in the calling process 102. In the log storage subroutine, first, in a judgment 201, it is judged by the timer 18 whether a set time (for example, 5 seconds) has elapsed. If the time has elapsed, the process proceeds to step 202; Processing 20
In step 2, the timer 18 is reset, and the process proceeds to step 204. In the determination 203, it is determined whether or not an event such as a processing start, a processing end, an alarm occurrence, an alarm release, and an automatic tool change (ATC) start has occurred. If the event has not occurred, the process returns to the judgment 201, and if the event has occurred, the process proceeds to the judgment 204.

In the judgment 204, it is judged whether or not the log data is related to the driving operation (whether or not the data is classified 0). Processing 2 if it is not related to driving operation of category 0
09, if it is related to the driving operation, process 205
Proceed to. In step 205, the current operation state is compared with the previous operation state. The previous operation state is stored in the RAM 13 at the time of the previous log storage. Next, in judgment 206, it is judged whether or not the current operation state is different from the previous operation state. If the current operation state is the same as the previous time, the process returns to the judgment 201 and repeats the loop without saving the log data. If the current operation state is different from the previous operation state, the process proceeds to step 207, and the data of the current operation state is stored as the previous data. Next, the process proceeds to step 208.

In the process 209, a process of extracting log data other than the driving operation is performed. That is, the alarm information (category 1) performs a process of extracting log data when an event occurs (when an alarm signal is generated, when an alarm signal is released, and the like). The tool information (category 2) performs a process of extracting log data for a tool mounted on the spindle when an event occurs (such as when an automatic tool change operation starts). The measurement information (category 3) is extracted as log data when an event occurs (for example, when outputting measurement data such as when a DPRINT instruction is executed).

At this time, if the alarm information is of the category 1, the information is stored after performing appropriate conversion according to the category, such as converting an alarm signal into an alarm number and a message. In the alarm information, only the alarm number is stored in the section 0 as a part of the information on the driving operation. Category 2
In the case of the tool information of, the cumulative machining time at the last tool change,
Cumulative cutting time and cumulative machining time at the time of tool change,
Based on the accumulated cutting time and the rapid traverse time, a tool use time, a cutting time, and the like are calculated and recorded. The previous and current cumulative machining time and cumulative cutting time are stored in the RAM 13. In step 208, the log data is stored in the RAM 13
Is stored in the log area 134. When saving log data,
The current cumulative machining time and cumulative cutting time are stored as previous data. After the process 208, the process returns to the caller.

As described above, the log data relating to the driving operation and the like collected at predetermined time intervals by the timer 18 is stored only when it is different from the previous driving state, alarm state, and the like. It is possible to prevent the size of 141 from becoming unnecessarily large, and to record only the minimum data necessary for knowing the operation state of the machine tool. Further, the capacity of the log area 134 can be reduced, and the cost as the NC device can be reduced.

FIG. 5 is a diagram showing a display screen of the performance information. When "management function" and "NC recorder" are selected from the main menu displayed on the display means 15 of the NC apparatus 1, the screen of FIG. 5 is displayed. This screen displays the contents of the performance information file 142. The performance information file 142 is created by performing a totalizing process on the log file 141 on the date specified by the operator by the performance totalizing program 132. At the top of the screen, the date and capacity of the log file 141 that has been subjected to the tallying process are displayed. At first, the result information of the previous day is displayed.

The performance information includes a processed product performance and an operation rate. In the processed product results, each processed product is displayed by the O number of the startup NC processing program, and the comment of the startup NC processing program, the number of completed processes, and the processing time (cumulative processing time for the processed product) are displayed on the same line. . The occupancy rate is
The numbers and graphs are displayed at the bottom of the screen. The operation rate is based on the processing time (cumulative processing time: for example, the time during which the NC processing program is activated) and the operation preparation time (cumulative time in the operation ready state), and the operation rate = (processing time / operation preparation time). It is calculated by × 100 [%]. The machining time and the operation preparation time are obtained by totaling the log file 141 by the performance totalizing program 132. As a result, the number of processed products and the cumulative processing time of each processed product on the designated date are displayed in a list, the processed product performance can be grasped at a glance, and the operating rate of the machine tool can be also grasped at a glance.

The "F1" to "F6" keys displayed at the bottom of the screen are used to switch the screen display from FIG. 5 to FIG. When the "F7" key is pressed, the date of the log file 141 can be specified, and a message and a prompt for inputting the date are displayed in an operation explanation column at the bottom of the screen. As a result, the date of the log file 141 to be tabulated or displayed can be selected and designated as a desired date.

The "F8" key is for storing the log file 141 on a recording medium such as a flexible disk via the medium input / output device 17. If the user presses the "F8" key and further specifies a date range, the log file 141 in that date range can be copied and stored on a recording medium. The log file saved on the recording medium in this way
The data can be read by a general personal computer application such as a spreadsheet, and various kinds of tallying processing can be performed on the application.

The "F9" key is for terminating the "NC recorder" and returning to the previous "management function" screen. When the machine tool is processing, the O number of the currently executed NC processing program and the generated alarm are displayed on the top line of the screen. If the processed product results cannot be displayed on one screen, all data can be confirmed by switching the displayed page using a “previous page” key and a “next page” key (not shown).

For log data that cannot be displayed on one screen, all data can be confirmed by switching display pages using a “previous page” key and a “next page” key (not shown). However, due to the limitation of the screen width, all the fields of the log data are not displayed on the screen, but only some of them are displayed. For example, the date field records the date, but the screen displays only the date.

FIG. 7 is a diagram showing a display screen of log data: driving operation. From another screen, this screen can be displayed by pressing the "F3" key. This screen is for extracting and displaying only the log data of the log file 141 of the specified date in the section 0.

On the screen, one measurement data is displayed divided into two lines. As described above, the measurement data on which the automatic measurement has been performed can be selected and displayed in the order of occurrence, which is useful for monitoring a processing error of a workpiece.

In the above embodiment, the NC device is a so-called personal computer NC device using a personal computer. However, the present invention is not limited to the personal computer NC device, and an auxiliary memory of sufficient capacity to record operation information is provided. If it is provided with a device, it may be a device dedicated to a normal NC.

[0052]

Since the present invention is configured as described above, it has the following effects.

The local NC unit attached to each machine tool records the log data as a log file for each day, and performs a tallying process from the log file to create a performance information file. Advanced production management can be performed at low cost without laying.
In addition, even if the NC device is connected to a network and normally performs processing by sending data to a production management computer, a local NC device may be used when an abnormality such as a network failure occurs.
By switching to perform data processing in the apparatus, it is possible to prevent the loss of machine operation information. Further, since the log file is a relatively small-capacity file for each day, it is possible to perform information totaling processing and search processing at high speed.

Since the contents of the log file and the result information file can be displayed by designating a date, necessary information can be selected and viewed with a simple operation.

The log data includes driving operation, alarm information,
Since it includes the section data of tool information and measurement information, it is possible to select only necessary information.

By selecting and displaying the log data division, only necessary information can be selected and viewed, so that early detection of an abnormality or failure and elucidation of the cause of the failure become easy.

Since the log data relating to the driving operation collected every predetermined time is stored only when it is different from the previous driving state, it is possible to prevent the log file from becoming unnecessarily large. In addition, it is possible to record only the minimum data necessary for knowing the operation state of the machine tool. Also, the capacity of the log area can be reduced, and the cost as the NC device can be reduced.

During the machining of the machine tool, the log data is stored in the RAM capable of high-speed processing, and is recorded on the fixed disk device at the end of the machining. Accurate machining becomes possible.
