PROBLEM TO BE SOLVED: To secure the continuous feed of the numerical controller by putting a block and a next successive block together, putting successive blocks together until the movement quantity of the instruction of the composite block becomes larger than a minimum movement quantity, and performing feed control with the instruction of the composite block. SOLUTION: A machining program analysis part 1 analyzes a machining program and a one-block movement quantity calculation part 3 calculates the quantity of movement by the instruction of one block of the analyzed machining program. A comparison part 5 compares the calculated quantity of movement by the instruction of the one block with the minimum movement quantity determined by the one-sampling period time and feed speed of the numerical controller and the comparison result is inputted to a block composing process part 7; when the quantity of movement by the instruction of one block is smaller than the minimum movement quantity, a block whose movement quantity is smaller than the minimum movement quantity and a next block succeeding thereto are connected together to perform the feed control with the instruction of the composite block.
