PURPOSE:To lead out optimum feeding speed and rotation number of a tool to perform working by storing preliminarily data required for numerical control in a storage device. CONSTITUTION:The working tool and optimum feeding speed and rotation number of the working tool corresponding to materials to be worked and the degree of finishing are stored in a storage device 4 from an input/output device 5. Meanwhile, working conditions are inputted to the storage device 4 from a program decoding device 2a. Optimum feeding speed and rotating number of the tool read out from the storage device 4 are read into an arithmetic unit 2b, and the arithmetic unit 2b performs the operation in accordance with a working locus read from the decoding device 2a and optimum feeding speed and rotation number of the tool from the storage device 4 and issues commands to a servo motor 3a and a spindle motor 3b which drive the tool. |
