1. A numerical controller that is connected to a machine tool having axes and a storage device and that controls the machine tool by executing a machining program that is made up of a plurality of blocks and that controls acceleration/deceleration of the axes, the numerical controller comprising:

  • a program execution unit that runs the machining program;

    a program look-ahead unit that looks ahead at the machining program in parallel with running the machining program;

    a speed reduction block detection unit that detects a speed reduction block in the machining program, where the speed reduction block is a block at which the number of blocks to be looked ahead relatively decreases;

    a speed information storage unit that calculates feed rate at each of the axes from a table feed rate at the speed reduction block and stores speed information which is information on the feed rates in the storage unit; and

    a speed information read unit that reads out the speed information from the storage unit and applies the speed information as the feed rate at each of the axes.
