Abstract

A display device acquires and displays information on a machine tool that includes a spindle for relatively rotating workpiece and a cutting tool and feed axes for relatively feeding the workpiece and the cutting tool and that performs machining on the workpiece while making the cutting tool and the workpiece swing relatively, and includes: a first information display unit that displays first information indicating a position to which the cutting tool is relatively fed with respect to the workpiece; a second information display unit that displays second information indicating a relationship between the phase of the spindle and the positions of the feed axes; and a range selection unit that selects part of the first information as a selection range, and the second information display unit changes the display range of the second information such that the display range corresponds to the selection range selected by the range selection unit.

First claim

What is claimed is:

1. A display device which acquires and displays information on a machine tool that includes a spindle for relatively rotating a workpiece and a cutting tool and at least one feed axis for relatively feeding the workpiece and the cutting tool and that performs machining on the workpiece while making the cutting tool and the workpiece swing relatively, the display device comprising:
a first information display unit that displays first information indicating a position to which the cutting tool is relatively fed with respect to the workpiece;
a second information display unit that displays second information indicating a relationship between a phase of the spindle and a position of the feed axis; and
a range selection unit that selects part of the first information as a selection range,
wherein the second information display unit changes a display range of the second information such that the display range corresponds to the selection range selected by the range selection unit.

2. The display device according to claim 1 , further comprising: a range change unit that changes the display range of the second information,
wherein the range selection unit changes the selection range such that the selection range corresponds to the display range of the second information which is changed by the range change unit.

3. The display device according to claim 1 , further comprising: a third information display unit that displays third information indicating a chronological change of position information, torque information, speed information or acceleration information of the feed axis,
wherein the third information display unit further displays the third information or the second information display unit and the third information display unit switch the second information with the third information so as to display the third information, and
the third information display unit changes a display range of the third information such that the display range corresponds to the selection range selected by the range selection unit.

4. The display device according to claim 3 , further comprising: a range change unit that changes at least any one of the display range of the second information and the display range of the third information,
wherein the range selection unit changes the selection range such that the selection range corresponds to the display range of the second information or the display range of the third information which is changed by the range change unit.

5. The display device according to claim 1 , further comprising: an enlarged information display unit that displays enlarged information of the first information,
wherein the enlarged information display unit further displays the enlarged information or the second information display unit and the enlarged information display unit switch the second information with the enlarged information so as to display the enlarged information, and
the enlarged information display unit changes a display range of the enlarged information such that the display range corresponds to the selection range selected by the range selection unit.

6. The display device according to claim 5 , further comprising: a range change unit that changes at least any one of the display range of the second information and the display range of the enlarged information,
wherein the range selection unit changes the selection range such that the selection range corresponds to the display range of the second information or the display range of the enlarged information which is changed by the range change unit.

7. The display device according to claim 3 , further comprising: an enlarged information display unit that displays enlarged information of the first information,
wherein the enlarged information display unit further displays the enlarged information or the second information display unit, the third information display unit and the enlarged information display unit switch the second information or the third information with the enlarged information so as to display the enlarged information, and
the enlarged information display unit changes a display range of the enlarged information such that the display range corresponds to the selection range selected by the range selection unit.

8. The display device according to claim 7 , further comprising: a range change unit that changes at least any one of the display range of the second information, the display range of the third information and the display range of the enlarged information,
wherein the range selection unit changes the selection range such that the selection range corresponds to the display range of the second information, the display range of the third information or the display range of the enlarged information which is changed by the range change unit.
