TITLE OF THE INVENTION INSERT CARTRIDGE AND TOOLHOLDER FOR AUTOMATIC INSERT CHANGER ABSTRACT OF THE DISCLOSURE A toolholder and insert cartridge are disclosed in which an insert cartridge holds multiple, similarly- shaped inserts in a face-to-face relation in a storage chamber. The insert cartridge has means thereon for dispensing individual inserts one at a time and can be adapted to be held and mover by robotic arm or a reciprocal moving holder. A toolholder having an insert pocket with a movable insert seat therein is utilized with the insert cartridge. A reciprocably movable draw- bar moves the insert seat in the toolholder pocket back and forth so as to clamp and unclamp a cutting insert. When it is signaled to change the insert, the drawbar moves the insert seat out of the insert pocket, thereby unclamping the insert. The insert is then removed from the insert seat and the insert storage cartridge is positioned in proper alignment with the toolholder. The cartridge and toolholder are then engaged so that the insert seat engages the dispensing means on the car- tridge unit. The drawbar is then actuated so that the insert seat is moved inwardly into the pocket of the -1- toolholder, thereby taking an insert from the storage chamber of the insert cartridge and clamping it in the insert pocket of the toolholder. The toolholder and the insert cartridge are thereby disengaged and the robotic arm on the insert cartridge may move it back to storage position so that machining may continue. -2-
