ABSTRACT:
In a reciprocating travelling shear in which a tool post travels reciprocatingly in the travelling direction of a travelling material and a cutting tool held by the tool post is made to move vertically by press mechanism to cut the material, the press mechanism is driven by a first DC motor, which is controlled by first numerical control means, the reciprocating travelling of the tool post is controlled by a second DC motor, which is controlled by second numerical control means, and the second numerical control means supplies a cut command to the first numerical control means thereby to drive the first motor when the tool post has travelled a predetermined distance.
