1. In a computer controlled machine for performing punching and thermal cutting of workpieces, the combination comprising:

  • A. a frame having a base and a head;

    B. a ram assembly mounted on said head and including a ram member mounted for reciprocation on a vertical axis relative to said base and drive means for said ram member to effect such reciprocation;

    C. first tool mounting means in said head including means for supporting a punch for reciprocation with said ram member;

    D. second tool mounting means on said base including means for supporting a die in coaxial alignment with said axis of reciprocation of said ram member, said axis of reciprocation defining the work station and said tool mounting means being coaxial therewith;

    E. a workpiece guidance system for moving a workpiece on said base of said frame below said ram assembly and along X and Y axes relative to said work station;

    F. thermal cutting means including power generating means, a thermal cutting head mountable in one of said tool mounting means with its thermal cutting axis coaxially aligned with said axis of reciprocation of said ram member, and conduit means for coupling said head and power generating means;

    G. waste removal means including a waste removal member mountable in the other of said tool mounting means, said machine including at last a portion of said conduit means for coupling to said thermal cutting head upon mounting in said one tool mounting means, and means for coupling said thermal cutting head and said portion of said conduit means upon such mounting; and

    H. computer control means for selectively and alternately operating one of (i) said drive means for said ram member to reciprocate a punch and (ii) said thermal cutting means and for operating said guidance system to move a workpiece along said X and Y axes for operation thereon by the selected one of said ram member and thermal cutting means at said work station.
