Abstract
Provided is a numerical control device whereby the execution state of a program can be more intuitively confirmed. This numerical control device, which controls a machine tool on the basis of a program, comprises: a program execution unit having a prescribed function for executing a program in response to the rotation of a manual handle of the machine tool; an execution state identification unit that identifies the execution state of the program; and a haptic controller that generates haptic feedback in the manual handle on the basis of the prescribed function and the execution state of the program.
Claims3
A numerical control device for controlling a machine tool based on a program, the numerical control device comprising:
- a processor, wherein the processor is configured to:
- have a predetermined function of executing the program according to rotation of a manual handle of the machine tool;
- specify an execution state of the program;
- cause haptic feedback to be generated in the manual handle based on the predetermined function and the execution state of the program;
- set action definition data that defines the haptic feedback to be outputted to the manual handle;
- select a type of the haptic feedback based on the action definition data, the predetermined function, and the execution state of the program;
- and
- decide a parameter related to the haptic feedback based on the type of the haptic feedback,
- wherein the processor specifies a command speed of a block of the program, and selects, as the type of the haptic feedback, resistance tactile sense associated with a manual handle retrace function in the action definition data and the command speed of a block of the program,
- wherein the processor generates the resistance tactile sense according to the command speed by the haptic feedback, using the decided parameter.
