Abstract: A display control device according to an embodiment includes a display control unit for controlling display of time-series data indicating a change in a detected value detected by the detection unit in a process of execution of a machining program, and a receiving unit for receiving a predetermined input based on the time-series data. The display control unit controls display of (a) a program name and (b) at least one of a block number and a program line of the machining program associated with the predetermined input received by the receiving unit.

Abstract: A display control device according to an embodiment includes a display control unit. In the display control device, when an instruction to change a rotating speed or a feed rate of a tool is received during execution of a machining program, information on a block or line of the machining program being executed when the change instruction is received and a change corresponding to the change instruction are associated with each other. Upon receiving selection of a change instruction, the display control unit displays (a) information on either of the block or a line of the machining program and (b) the change on a screen.

Abstract: A display control device according to an embodiment controls display of a state of a machine tool that includes (i) an attachment portion to which a tool is attachable, (ii) a numerical control unit for controlling (a) movement of the attachment portion and (b) a rotating speed of the tool in accordance with a machining program and (iii) a vibration detection unit for detecting vibration of the tool. This display control device includes a display control unit for controlling display of time-series data indicating (i) a change in a vibration level detected by the vibration detection unit and (ii) a change in the rotating speed of the tool. Upon receiving an instruction to change the rotating speed, the display control unit controls the display so that a marker indicating the change instruction is superimposed on the time-series data.

Abstract: 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.
