摘要: In a numerical control device for performing a control axis switch, each of a plurality of control axis units includes an axis movement amount conversion unit configured to convert a movement amount of a servo motor into a movement amount corresponding to each of the control axis units of the plurality of control axis units, an axis position data storage unit, and a control object axis position data storage unit configured to store an axis position of a control object at a time when the control object is separated from a single drive unit, and an axis position stored in the axis position data storage unit is configured to be updated by using the movement amount of the servo motor, regardless of whether or not the control object is connected by a control axis switch unit to the control axis unit.

摘要: A numerical controller that is capable of independently controlling multiple control groups can cause a machine to simultaneously execute multiple operations. The numerical controller includes a program analysis unit that analyzes a program and distinguishes the commands for the multiple control groups from each other, and a program execution unit that executes the commands for the multiple control groups independently on a per-control-group basis.

摘要: A numerical controller for moving a movable object by axis control includes a distance determination unit for setting at least one of a feed speed or an in-position width in accordance with a distance between an interference area where entry of the movable object is prohibited and the movable object. According to this configuration, a numerical controller capable of controlling a speed in consideration of an interference area is provided.

摘要: A numerical controller controls a machine having at least one axis based on at least one program. The numerical controller includes an actual machining time measuring unit that measures an actual machining time which is an actual time taken for execution of at least one block included in the program and a display unit that generates display data indicating a relation between the block and the actual machining time of the block.
