<p>An automatic milling or grinding machine provided with a rotationally and rectilinearly displaceable workpiece support is disclosed. Sets of information relating to the law of a camming surface to be formed on a workpiece and to workpiece-dependent parameters determining dimensional characteristics of the camming surface, respectively, are stored in the machine. Related items of information derived from each set are operatively associated with one another and a succession of angle information signals are generated, the succession defining a circular arc corresponding to one on which the axis of rotation of a given roller follower would move on following the camming surface. The machine provides pairs of co-ordinate displacement command signals in response to each angle information signal and applies the command signals to orthogonal co-ordinate drive means arranged to displace the workpiece support along the circular arc in a plane perpendicular to the rotational axis of the workpiece support.</p> |
