  For example, “(edit)” indicates that the button unit 55 for editing has been contacted or released, but a signal indicating editing has not been input to the control panel 80. On the other hand, “editing” indicates that the button unit 55 for performing editing is touched or released, and a signal indicating editing is input to the control panel 80.

  At “15:10:54”, the state is “DOWN”, and the operation content is “(edit)”. This indicates that at 15:10:54, for example, the operator's finger has touched the button portion 55 for editing. At “15:10:55”, the state is “UP” and the operation content is “edit”. This indicates that at 15:10:55, the operator's finger has left the button section 55 for editing, and a signal indicating editing has been input to the control panel 80. That is, from 15:10:54 to 15:10:55, it can be understood that the operator operates the button unit 55 for editing and the control panel 80 recognizes the operation of the operator.

  At “15:15:10”, the state is “−”, and the operation content is “setting”. This indicates that at 15:15:10, for example, the operator's finger operated the switch 54a, button 54b or keyboard 54c for setting, and a signal indicating the setting was input to the control panel 80. That is, at 15:15:10, it can be understood that the operator operates the operation unit other than the touch panel 54d, and the control panel 80 recognizes the operator's operation.

This indicates that at 15:38:30, the operator's finger has left the non-operation part of the touch panel 54d, for example, the part displaying the graphic of the touch panel 54d or the blank part. That is, from 15:38:29 to 15:38:30, the operator's finger touches the button part 55 for setting the machining position of the workpiece, and the finger is slid as it is, so that the touch panel 54d It can be understood that it has moved to the non-operation part and released. At this time, the control panel 80 does not recognize the operation of the operator, that is, the operation of the button unit 55 for setting the machining position of the workpiece.

  At “15:38:49”, the state is “DOWN” and the operation content is “——”. This indicates that, for example, at 15:38:49, the operator's finger touches a non-operation part of the touch panel 54d, for example, a part displaying a graphic of the touch panel 54d or a blank part. At “15:38:30”, the state is “UP”, and the operation content is “(position)”. This indicates that at 15:38:30, the operator's finger has left the button portion 55 for setting the machining position of the workpiece. That is, from 15:38:49 to 15:38:50, the operator's finger touches the non-operation part of the touch panel 54d, and the finger is slid to set the machining position of the workpiece. It can be understood that the button portion 55 has been moved and released. At this time, the control panel 80 does not recognize the operation of the operator, that is, the operation of the button unit 55 for setting the machining position of the workpiece.

  When the teaching pendant 15 is connected to the operation panel 54 and the key or switch of the teaching pendant 15 is operated, the control panel 80 stores the operation history of the key or switch. When the operation history of the key or switch of the teaching pendant 15 is displayed on the touch panel 54d, the operation history of the key or switch of the teaching pendant 15 is displayed in a color different from the operation history of the switch 54a, the button 54b, the keyboard 54c, and the touch panel 54d. To do. For example, the operation history of the switch 54a, the button 54b, the keyboard 54c, and the touch panel 54d is displayed in red, and the operation history of the key or switch of the teaching pendant 15 is displayed in green. The column indicating “state” of the operation history displays the operation state of the key or switch of the teaching pendant 15 as “−”, and the column indicating “time” and the column indicating “operation content” include the switch 54a and the button 54b. Or, similarly to the keyboard 54c, the operation time and operation contents of the key or switch of the teaching pendant 15 are displayed.

  The operation history image includes a plurality of button units 56 as an operation unit. The plurality of button units 56 include an “input / output menu” button, a “today” button, a “return one day earlier” button, a “go forward one day” button, and a “date selection” button. FIG. 4 is an image in which the “today” button is selected.

  FIG. 5 is a diagram illustrating an example of an image showing a date list of the operation history. When the “date selection” button is selected, the touch panel 54d displays a date list of recorded operation histories (hereinafter referred to as a date list) as shown in FIG. The date list displays dates for 30 days. The date list may display dates that are less than 30 days, or may display dates that are more than 30 days. The date list includes a “No” column and a “history date” column. The “No” column displays 1 to 30 in ascending order. The “history date” column displays the date when the operation history is stored in correspondence with the numbers in the “No” column. A small number in the “No” column corresponds to the new date, and a large number corresponds to the old date. The date in the “History Date” field also functions as a button. When the operator selects a date in the “history date” column, the touch panel 54d displays an operation history of the selected date (see FIG. 4).

  In the machine tool according to the embodiment, when the operator's finger touches the button unit 55 displayed on the touch panel 54d, the contact of the button unit 55 and the non-recognition of the operation of the button unit 55 are stored and displayed. . The control panel 80 does not recognize the operation of the button unit 55 because it cannot be determined that the operation on the button unit 55 has been completed simply by touching. Further, when the contact release of the button unit 55 is detected and the operation of the button unit 55 is recognized, for example, after touching the button unit 55, the operator's finger is separated from the button unit 55, and the control panel 80 is connected to the button unit 55. When the operation is recognized, the fact is memorized and displayed. When the finger is released from the button unit 55 and the input to the button unit 55 is recognized, it can be determined that the operation on the button unit 55 is completed. Further, when the contact or release of the non-operation part of the touch panel 54d is detected, for example, when the operator's finger comes in contact with the figure or the blank area displayed on the touch panel 54d or leaves after the contact, The contact release and the non-recognition of the operation of the button unit 55 are stored and a message to that effect is displayed. This is because there is no input to the button unit 55 when the operator's finger contacts the non-operation unit or moves away from the non-operation unit. Corresponding to whether or not the input to the button unit 55 is recognized, the contact and release of the button unit 55 are displayed in the operation history, and the influence on the input / output operation analysis of the control panel 80 is avoided.

  When contact release of the button unit 55 is detected after detecting contact of the button unit 55, it is determined that the operator's finger has pressed the button unit 55 to complete the operation on the button unit 55.

  Further, since it cannot be determined that the operation on the button unit 55 has been completed only by touching, the operation content of the button unit 55 is displayed to indicate the touched button unit 55, and the input to the button unit 55 is not recognized. In order to show that, parentheses are displayed. For example, “(edit)” is displayed. Further, the operation content of the button unit 55 is displayed to indicate the contact release button unit 55, and parentheses are not displayed to indicate that the input to the button unit 55 is recognized. For example, “edit” is displayed.

  Further, in order to indicate contact or release of a part other than the button part 55 on the touch panel 54d, a symbol different from the operation content of the button part 55 and the parentheses is displayed. For example, “――――” is displayed. Therefore, an operation for a part other than the button unit 55 can be displayed separately from an operation for the button unit 55.

  Further, the operation history by the teaching pendant 15 is displayed in a color different from the operation history by the button unit 55 of the operation panel 54 to distinguish between the two. The teaching pendant 15 is only an example of the second operation unit. Instead of the teaching pendant 15, a personal computer may be connected to the operation panel 54 as the second operation unit.
