A numerical controller according to the present invention stores comparative relationship between parameters related to setting of the numerical controller, extracts data having comparative relationship among parameters related to the setting of the numerical controller based on the stored comparative relationship, and causes a display to display the data having the comparative relationship in association with each other.

A numerical controller according to the present invention stores comparative relationship between parameters related to setting of the numerical controller, extracts data having comparative relationship among parameters related to the setting of the numerical controller based on the stored comparative relationship, and causes a display to display the data having the comparative relationship in association with each other.

An object is to more appropriately perform settings in the setting of the control of a machine tool. A setting device includes: a first reception unit which receives the specification of a first setting value for at least one or more parameters on the control of a machine tool; a second reception unit which receives the specification of a second setting value for the parameter after the reception of the first setting value; a third reception unit which receives the specification of a selection condition for determining which one of the first setting value and the second setting value is selected; and a selection unit which selects, based on the selection condition whose specification is received by the third reception unit, any one of the first setting value and the second setting value as a setting value that is applied to the parameter.

A machine tool management system includes a machine tool, a memory, a display, and a control circuit. The control circuit is configured to record, in the memory, a time point at which detection information with respect to a machine tool is detected and the detection information corresponding to the time point; determine selected detection information among the detection information to satisfy a determination condition; record, in the memory, the selected detection information corresponding to the time point; display a list of the selected detection information according to predetermined display items; extract from the memory at least part of the detection information including one of the selected detection information corresponding to one display item selected among the display items listed on the display; and to display a graph of a change over time in data included in the at least part of the detection information.

A method and apparatus for managing a display of an assembly model. The assembly model is displayed in an initial state within a first display area in a graphical user interface. A first display state of an item of the assembly model is changed to a second display state within the first display area in response to receiving a first type of input. The second display state of the item of the assembly model is changed to a third display state within the first display area in response to receiving a second type of input. An entry is added to an assembly hierarchy within a second display area in the graphical user interface in response to the second display state of the item changing to the third display state.

A vibration information display device includes a monitor, a vibration information acquisition unit, an operating information acquisition unit, a storage unit, and a display control unit. The monitor displays information on the chatter vibrations. The vibration information acquisition unit acquires vibration information when the chatter vibrations are detected. The operating information acquisition unit acquires operating information of the machine tool when the chatter vibrations are detected. The storage unit stores the acquired vibration information and operating information. The display control unit displays the vibration information and the operating information stored in the storage unit on the monitor. Alternatively, the display control unit displays the vibration information stored in the storage unit on the monitor together with trajectory information of a blade edge of the tool included in the operating information.

According to one embodiment of the present disclosure, a motor monitoring device that can easily ascertain the state of a motor comprises a rotational speed acquisition unit that acquires the rotational speed of a motor that operates in accordance with an operation program, an output value acquisition unit that acquires an output value for the motor, and a graph display unit that plots a marker that represents a combination of the rotational speed and the output value at a graph area where one axis is the rotational speed and the other axis is the output value. The graph display unit has a unit area setting unit that sets a plurality of unit areas that divide the graph area into a grid and a format modification unit that modifies the display format of the marker by unit area in accordance with a prescribed indicator.
