摘要： To provide a punch press which can realize the high hit rate and the energy saving in the punch drive. A plate material transfer control means 32 and a ram axis control means 33 controlled synchronously are provided. The plate material is started to transfer when a punch tool 6 reaches a pullout height HH2 after punching and it is arranged to come to a height HH1 which is likely to contact with the plate material when completing transferring the plate material. The ram axis control means 33 rotates a servomotor 19 in one direction. Moreover, the ram axis control means 33 controls in a motor speed pattern VP based on the distance of transferring the plate material after the punch tool 6 goes up from the pullout height HH2 and the servomotor 19 is prevented from stopping as possible. The motor speed pattern VP is made to be a trapezoid pattern that the acceleration is constant.

摘要： It is an object of the present invention to provide a machine tool that the process accuracy does not deteriorate even if the accuracy of the machine itself changes to some extent. A work support means 3 of a spindle 8 etc. to support a work (W), a cutting means 4 of a movable feed bar 9 to the work support means 3 to process the work (W) and a tool base 10 and the like and a control unit 2 are provided. The control unit 2 controls the movement of the cutting means 4 by the measured positional information based on a process origin (Ow) of the work support means 3. The position measurement means 25 like a linear sensor is provided as the means to measure the position to the moving direction of the cutting means 4 based on the process origin (Ow).
