A computer controlled machine performs punching and thermal cutting of workpieces at the same work station in the machine. First tool mounting means is provided on the ram assembly of the punch head and supports a punch for reciprocation by the ram member. Second tool mounting means is provided on the base of the machine for supporting a die in coaxial alignment with the punch. The machine includes thermal cutting means including power generating means, a thermal cutting head mountable in one of the tool mounting means with its cutting axis aligned with the axis of reciprocation of the ram member, and conduit means for coupling the head to the power generating means. Waste removal means is provided for mounting in the other of the tool mounting means. Computer control means will selectively and alternately operate the drive means for the ram member and the thermal cutting means, as well as move the workpiece along X and Y axes relative to the work station at which both are selectively operable. The thermal cutting means may be a laser cutting head utilizing oxygen assist for the cutting operation, or it may be a plasma cutting head. The cutting heads and cooperating waste collection devices may be stored in an automatic tool changing device for automatic insertion into the tool mounting means in response to commands from the computer control.
