Abstract
A programmable controlled turnblanking machine comprising a blanking apparatus having a pair of blank dies each provided with a cutting edge and disposed in a strip feed direction on a bed to cut out blanks of predetermined shape and size from a strip by means of the cutting edges of the blank dies, one of the blank dies being disposed in front in the strip feed direction and preventing from sliding in the strip feed direction, and the other blank disposed in the rear in the strip feed direction so as to be slidable on the bed in the same direction, both blanked dies being rotatably supported on the bed; a teaching unit for inputting a slide distance X of the rear blank die as well as rotational angles .theta..sub.1 and .theta..sub.2 of both front and rear blank dies and setting positioning data for the blank dies as program data; and a control box for automatically setting initial positions of the paired blank dies in accordance with a program based on the said program data set by the teaching unit and controlling blank cutting operations of the blanking apparatus automatically.
