First and second tool control blocks respectively precede and follow a corner on a tool path. A pulse distribution computation based on NC command data in the second block is not executed at the instant that a pulse distribution computation based on NC command data in the first block ends. Rather, a pulse distribution computation based on the NC command data in the second block is performed starting at the instant that a feed speed based on the NC command data in the first block is reduced to a prescribed speed by being decelerated. As a result, the torch of a gas cutting machine or the like will cut the corner portion quickly with a high degree of accuracy and without cutting the corner to an overly rounded shape.
