Numerical controller and machine tool

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.
