Abstract
A virtual manual handle is displayed on a screen of a display device of a numerical controller to simultaneously specify an operation amount and set a magnification of an axial movement amount with respect to this operation amount based on an operator's operation on the displayed manual handle.
Claims3
A numerical controller that controls a machine tool including at least one axis, the numerical controller comprising:
- a processor configured to:
- detect a touch operation on a predetermined operation area in a display area of a touch panel, wherein the predetermined operation area defines a virtual handle displayed in the display area;
- specify a drag operation for the virtual handle in the operation area of the touch panel;
- perform an arithmetic operation based on a start point position of the drag operation for the virtual handle and an end point position of the drag operation for the virtual handle, and specify an operation amount of the drag operation and an operation direction with respect to the drag operation for the virtual handle;
- perform an arithmetic operation based on the drag operation for the virtual handle, and determine a magnification of a movement amount of the axis with respect to the operation amount of the drag operation;
- generate a pulse for moving the axis of the machine tool based on the operation amount and operation direction of the drag operation for the virtual handle, and the magnification of the movement amount of the axis of the machine tool with respect to the operation amount of the drag operation of the virtual handle;
- and
- control, via a servo controller, movement of the axis of the machine tool based on the generated pulse.
