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 touch panel that can detect a touch operation on a predetermined operation area in a display area;
- a touch position detecting unit that specifies a drag operation in the operation area;
- an operation amount arithmetic operation unit that performs an arithmetic operation based on a start point position of the drag operation and an end point position of the drag operation, and specifies an operation amount of the drag operation and an operation direction of the drag operation;
- a magnification arithmetic operation unit that performs an arithmetic operation based on the drag operation, and determines a magnification of a movement amount of the axis with respect to the operation amount of the drag operation;
- a pulse generating unit that generates a pulse for moving the axis based on the operation amount of the drag operation and the operation direction of the drag operation specified by the operation amount arithmetic operation unit, and the magnification of the movement amount of the axis with respect to the operation amount of the drag operation determined by the magnification arithmetic operation unit;
- and
- a servo control unit that performs control to move the axis based on the pulse generated by the pulse generating unit.
