Abstract
A numerical controller includes an information storage unit that stores, in association with identification information assigned to a tool, coordinate conversion information used to convert a coordinate value in a rotating coordinate system into a coordinate value in a reference coordinate system, an information acquisition unit that acquires, from a machining program, a coordinate value that indicates a movement path of the tool to which the identification information is assigned, and a coordinate conversion unit that performs coordinate conversion of the coordinate value indicating the movement path acquired by the information acquisition unit, based on the coordinate conversion information stored in the information storage unit.
Claims5
A numerical controller comprising a processor,
- wherein the processor is configured to:
- store, in association with identification information assigned to a tool, coordinate conversion information used to convert a coordinate value in a rotating coordinate system into a coordinate value in a reference coordinate system;
- acquire, from a machining program, a coordinate value that indicates a movement path of the tool to which the identification information is assigned;
- and
- perform coordinate conversion of the coordinate value indicating the movement path acquired by the information acquisition unit, based on the coordinate conversion information stored in the information storage unit, wherein
- the coordinate conversion information includes coordinate difference information that indicates a difference between the rotating coordinate system and the reference coordinate system, and
- the processor is further configured to perform the coordinate conversion based on the coordinate difference information.
A numerical controller comprising a processor,
- wherein the processor is configured to:

- acquire, from a machine program, a coordinate value that indicates a movement path of the tool to which the identification information is assigned;
- and
- perform coordinate conversion of the coordinate value indicating the movement path acquired by the information acquisition unit, based on the coordinate conversion information stored in the information storage unit, wherein
- the coordinate conversion information includes reference machining direction information that indicates a reference machining direction of the tool, which is set for each tool, and
- the processor is further configured to perform the coordinate conversion based on the reference machining direction information and position information of the tool.
