  • System for adapting an automatic screw machine to achieve computer numeric control
    Patent number: 6662074
    Abstract: A system for adapting existing conventional screw machines to be capable of computer numerical control operation. The system incorporates the use of a VersaCam device which replaces the turret cam of a single spindle screw machine. The VersaCam system monitors the motion of the screw machine camshaft and actuates the turret slide in synchronization with the camshaft. The VersaCam system also provides a means of specifying the desired turret slide trajectory for any given job.
