Abstract
A numerical controller, which can handle information on a use tool, calculates the shape of a workpiece being machined, based on an input machining program, shape information of the use tool, shape information of a unmachined workpiece, and a tool trajectory, and sets, as a movable range of the tool, a range in which the tool never contacts the workpiece being machined, based on the calculated shape of the workpiece being machined, if manual operation is performed during machining.
Claims3
A numerical controller capable of handling information on a use tool, the numerical controller comprising:
- a machining program input unit configured to input a machining program, shape information of a use tool, and shape information of an unmachined workpiece;
- a workpiece shape calculation unit configured to calculate the shape of a workpiece being machined, based on the information of the use tool, the information of the unmachined workpiece, and a tool trajectory;
- and
- a movable range setting unit configured to set, as a movable range of the tool, a range in which the tool never contacts the workpiece being machined, based on the shape of the workpiece being machined, if manual operation is performed during machining.
