1. A numerical controller for controlling threading of a workpiece by a machine provided with a plurality of tools based on a program, the numerical controller comprising:
a chip division information input unit configured to receive input of a technique for operating the plurality of tools and an operation condition of the operation technique;
a multi-tool operation calculation unit configured to calculate movement command data including speed information and position information on the plurality of tools, such that respective cutting paths of the plurality of tools intersect, based on the operation method and the operation condition input by the chip division information input unit;
an interpolation unit configured to generate interpolation data based on the movement command data; and
a servo control unit configured to control a motor for driving the machine based on the interpolation data, wherein the movement command data calculated by the multi-tool operation calculation unit includes data related to a movement command in which simultaneous cutting from different positions is performed with a plurality of cutting tools including a first tool and a second tool different from the first tool among the plurality of tools.
