PROBLEM TO BE SOLVED: To enable molding inexpensive and small dispersion in working accuracy by incorporating working processes such as tap working, cutting working or welding working into a part of a progressive die process and automating the process. SOLUTION: An output arithmetic means 67 reads motion data stored into a tap working pattern storing means 66, calculates a control command value to a speed control means (a servo valve, in this case) and outputs the value, monitoring a slide position and a speed value so as to move a slide at prescribed speed along a motion curve based on this set value. As a result, position and speed of a slide driving means (a hydraulic cylinder, in this case) are controlled. When the slide comes at a starting position of tap working, working starting commands are outputted to the tap working devices 33, 43. When one cycle of slide motion is completed, a material feeding command is outputted to a material supplying device 58.
