Abstract
A method for warping the machine bed of a punching press, which machine bed has an aperture for carrying away punching parts and rubbish, compensates at least partially for a bending of the machine bed caused by the punching force during the punching operation. Thereby, forces acting transverse to the punching direction are introduced into the machine bed and/or forces acting transverse to the punching force direction are produced inside the machine bed, by means of which the machine bed warps in the direction towards the press ram and indeed such that it warps stronger in the area adjacent to the aperture than in the areas adjacent to its longitudinal sides.
