PROBLEM TO BE SOLVED: To correct feeding speed data of an operation program so as to be an optimum feeding speed in every working process by means of a correcting system with an override setting value. SOLUTION: This device is provided with a first feed mechanism MZ for relatively shifting a work W and a tool T in a direction along with its rotating shaft Z or the rotating work W, a second feed mechanism MX for relatively shifting the work W and the tool T in a direction orthogonal to the rotating shaft, a plurality of override setting devices (from J to N), a storage 37 wherein order from starting of the work is stored, each of the feeding speed in the first feed mechanism MZ and the second feed mechanism MX is related to the types of the override setting devices and stored, and a control device 36 for controlling actual feeding speed of the first feed mechanism and the second feed mechanism so as to be the feeding speed corrected based on a type of override setting device (any one from j to n) wherein the feeding speed stored in the storage is related to it and stored.
