Machine tool and display control device
A display control device includes a calculation unit for calculating a first rotating speed on the basis of a vibration level detected by a vibration detection unit when the vibration level has exceeded a predetermined value, a change receiving unit for receiving a change instruction for changing a second rotating speed that is a rotating speed when the vibration level has exceeded the predetermined value to the first rotating speed, and a display control unit for performing control to display, on an operation screen, the first rotating speed, the second rotating speed, and a ratio display unit indicating a change ratio to a third rotating speed specified by a machining program, and performing control to display the first rotating speed at a position in the ratio display unit corresponding to a change ratio of the first rotating speed to the third rotating speed.
1 . A display control device comprising:
a processor controlling display of an operating state of a machine tool including (i) an attachment portion to which a tool is attachable, (ii) a numerical controller controlling rotation of the tool in accordance with a machining program and (iii) a vibration sensor detecting vibration of the tool; and
a memory storing various programs including the machining program and set data,
wherein the processor calculates a first rotating speed on a basis of a vibration level detected by the vibration sensor when the vibration level has exceeded a predetermined value;
receives a change instruction for changing a second rotating speed to the first rotating speed, the second rotating speed being a rotating speed when the vibration level has exceeded the predetermined value; and
(i) performs control to display, on an operation screen, the first rotating speed, the second rotating speed, and a ratio display indicating, along a scale, a change ratio of a rotating speed to a third rotating speed specified by the machining program, the third rotating speed being a program-command spindle rotating speed represented as 100% on the scale, and (ii) performs control to display the first rotating speed at a position in the ratio display corresponding to a change ratio of the first rotating speed to the third rotating speed,
wherein when the processor has received the change instruction, the numerical controller performs control to change a control command value of a rotating speed of the tool to the first rotating speed.
2 . A machine tool comprising:
a processor controlling display of an operating state of the machine tool:
a memory storing various programs including the machining program and set data;
an attachment portion to which a tool is attachable;
a numerical controller controlling rotation of the tool in accordance with a machining program; and
a vibration sensor detecting vibration of the tool,
wherein the processor calculates a first rotating speed on a basis of a vibration level detected by the vibration sensor when the vibration level has exceeded a predetermined value;
receives a change instruction for changing a second rotating speed to the first rotating speed, the second rotating speed being a rotating speed when the vibration level has exceeded the predetermined value; and
performs control to display, on an operation screen, the first rotating speed, the second rotating speed, and a ratio display indicating, along a scale, a change ratio of a rotating speed to a third rotating speed specified by the machining program, the third rotating speed being a program-command spindle rotating speed represented as 100% on the scale, and performing control to display the first rotating speed at a position in the ratio display corresponding to a change ratio of the first rotating speed to the third rotating speed,
wherein when the processor has received the change instruction, the numerical controller performs control to change a control command value of a rotating speed of the tool to the first rotating speed.
3 . The machine tool according to claim 2 ,
wherein when the vibration level detected by the vibration sensor has exceeded the predetermined value, the processor enables an adjust button displayed on the operation screen to receive a change instruction to change the second rotating speed to the first rotating speed, and
when an input is performed on the enabled adjust button, the processor receives the change instruction.
4 . The machine tool according to claim 3 ,
wherein the processor calculates, as the first rotating speed, a first recommendation value higher than the second rotating speed and a second recommendation value lower than the second rotating speed, and
before enabling the adjust button, the processor displays a setting screen for receiving a setting instruction indicating which of the first recommendation value and the second recommendation value is to be selected.
