PURPOSE: To improve the working accuracy by performing the working to a work at the timing at which the work stops surely, and shortening a cycle time without generating a useless waiting time.
CONSTITUTION: The machine tool is provided with a work table containing servo-motors 20, 25, a working means containing a punch press driving part 43, waveform check circuits 41, 42, and a control means containing a microprocessor and a table control part 36. The work table can move at least in one direction in the plane, and is provided in order to attach a work. The working means works the work being in a still state attached to said work table. The waveform check circuits 41, 42 detect the moving speed, when the work table is moving. The control means decides a still state of said work in accordance with a result of detection of the waveform check circuits 41, 42, and controls a working timing of said working means.
