Numerical controller

A numerical controller for analyzing an axis movement command described in a machining program to generate block information of a path, the numerical controller comprising:

• a command analysis unit for analyzing the machining program in which the axis movement command for a plurality of successive line segment movements along a same axis is described in one block of the machining program in a reading processing for the one block to specify a plurality of coordinate values or a plurality of movement amounts corresponding to the plurality of the successive line segment movements along the same axis;
• and
• a block information generation unit for generating the block information for the plurality of the successive line segment movements along the same axis based on the plurality of coordinate values or the plurality of movement amounts of the successive line segment movements along the same axis,
• wherein an address to the same axis is described only once and a plurality of command values corresponding to the address to the same axis are described according to a predetermined order of the successive line segment movements along the same axis in the axis movement command, and the command analysis unit specifies a correlation between the address to the same axis and the plurality of command values according to the order.
