PROBLEM TO BE SOLVED: To easily perform machining for repeatedly performing the same machining operation by table form data, while cutting in like threading machining. SOLUTION: Pass tables Txc and Tzc of the X, Z axis for cutting-in operation for storing a cutting-in quantity are arranged. Pass tables Txs and Tzs of the X, Z axis for a threading cycle for storing threading one cycle operation are arranged. Cutting-in is set as a time reference 3c, and a threading cycle is set as a reference in a main spindle position 3s. Servomotors 5x and 5z of respective shafts are driven by adding (6x and 6z) a moving distance provided by reading out and interpolating (4xc and 4zs) a position and a moving distance stored in the pass table with respective shafts in response to a value of the respective references. Data quantity is not increased, and memory capacity is reduced due to being stored in the pass table by being divided into data on the cutting-in operation and data on the threading cycle of a specific pattern.
