Abstract
A numerical controller includes an extraction unit configured to extract at least one non-machining section from a tool path based on sensor information indicating a physical quantity detected by a sensor, a tool moving along the tool path, and the tool and a workpiece not coming into contact with each other in the non-machining section, a setting unit configured to set an end position of reverse movement in one non-machining section among the at least one non-machining section extracted by the extraction unit, the tool reversing along the tool path in the reverse movement, and a control unit configured to control the reverse movement.
Claims8
A numerical controller comprising:
- a processor configured to:
- extract at least one non-machining section from a tool path based on sensor information indicating a physical quantity detected by a sensor, a tool moving along the tool path, and the tool and a workpiece not coming into contact with each other in the non-machining section;
- set an end position of reverse movement in one non-machining section among the at least one non-machining section extracted by the extraction unit, the tool reversing along the tool path in the reverse movement;
- control the reverse movement;
- and
- receive information specifying the one non-machining section selected by a user among the at least one non-machining section,
- wherein the processor sets the end position in the one non-machining section based on the received information.
A control method for a machine tool, the control method comprising:
- extracting at least one non-machining section from a tool path based on sensor information indicating a physical quantity detected by a sensor, a tool moving along the tool path, and the tool and a workpiece not coming into contact with each other in the non-machining section;
- setting an end position of reverse movement in one non-machining section among the at least one extracted non-machining section, the tool reversing along the tool path in the reverse movement;
- controlling the reverse movement;
- and
- receiving information specifying the one non-machining section selected by a user among the at least one non-machining section,
- wherein in the setting the end position is set in the one non-machining section based on the received information.
