Hereinafter, a computer-readable recording medium storing a program capable of executing an information recording method and a recording method of a machine tool according to an embodiment of the present invention will be described with reference to Figs.

The information recording method of a machine tool according to an embodiment of the present invention includes the steps of (S10) displaying a list of machining information to be recorded on a screen, selecting an item to be recorded in the information list (S20) (S30) of operating the machine tool (S40), determining whether an abnormal operation has been detected in the item (S50), determining a rating of an error item when an error operation is detected (S60 And performing an action according to the class of the error item (S70).

As shown in FIG. 2, the step of displaying the list of machining information to be recorded on the screen (S10) displays a list listing a plurality of machining information on the screen so that the operator can easily confirm and select them.

In step S20 of selecting an item to be recorded from the information list, the operator selects a specific item to be recorded by the operator from the list on the screen as shown in FIG.

In the step S20 of selecting an item to be recorded among the information list, at least one item to be primarily recorded is selected at step S21. After completing the first selection, at least one item to be recorded is additionally recorded (Step S22). This can provide an opportunity for the operator to reduce errors in item selection for recording.

In the step of setting the rating of the selected item (S30), the selected plurality of items are classified / set into three grades as shown in the following [Table 1].

Rating range Back up operational information alarm Machine down [height] Within 5% of the limit O O O [middle] Within 10% of the limit range O O X [lowness] Within 15% of the limit O X X

Here, the limitation range may be set in advance through a separate algorithm for each item, but the present invention is not limited thereto.

Further, referring to FIG. 3, the classification of each item is classified into [Low], [Medium], and [High], and each class includes all of the lower grades.

That is, the [High] rating includes all items of the [Low] and [Medium] rating, and the [Middle] rating includes all items of the [Low] rating.

The step of operating the machine tool (S40) operates the machine tool. As described above, the machining is performed by various cutting tools such as grinding, side machining, hole machining, thread machining, and the like. Of course, the process is not intended to limit the invention.

In the step of determining whether an abnormal operation is detected in the item (S50), an error operation is detected in the process of detecting the operation of the machine tool in real time. Of course, real-time detection is performed in an infinite loop when an error operation is not detected.

If the error operation is detected, the step of determining the class of the error item (S60) determines whether the class corresponding to the detected item is [Low], [Medium], and [ High] class.

Thereafter, in step S70 of performing the action according to the class of the error item, a separate sequence is followed according to the class of the error item classified in the step S60. The step S70 of performing the action according to the class of the error item includes a step S71 of backing up the data near the error detection point, a step S72 of generating an alarm, and a step of stopping the operation of the machine tool S73).

That is, when the level of the error item is [low] in the step of determining the grade of the error item (S60), the step of performing the action according to the grade of the error item (S70) backs up the data near the error detection point The data of the area before and after the designated time is stored in the backup buffer based on the point where the error operation is detected and the error operation is detected as shown in FIG. . Of course, as shown in FIG. 1, after the data is backed up in the step S71, the operation returns to the step S50 to determine whether an abnormal operation is detected in the item, and the operation of the machine tool is detected in real time.

In the step of determining the class of the error item (S60), if the class of the error item is [intermediate], in the step of performing the action according to the class of the error item (S70), the data near the error detection point is backed up A step S71 and an alarm generating step S72 are performed.

That is, if the error category is [intermediate], data backup is performed in the step S71, and an alarm is generated in the step S72 so that the operator can check and take an action on the error item.

Of course, as shown in FIG. 1, after the operator confirms and measures the error item through the step S72, it returns to the step S50 to determine whether the abnormal operation is detected in the item, In real time.

In the step of determining the class of the error item (S60), if the class of the error item is [high], the step of performing the action according to the class of the error item (S70) A step S71 for generating an alarm, a step S72 for generating an alarm, and a step S73 for stopping the operation of the machine tool are carried out sequentially or simultaneously.

That is, if the error category is [high], the data backup is performed in the step S71, the alarm is generated in the step S72, the operation of the machine tool is stopped, To repair or replace.

Of course, when the error category is [high], the operation of the machine tool should be stopped. Therefore, the process is terminated without returning to the step S50 for determining whether an abnormal operation is detected in the item.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. It is.
