SYSTEM FOR ADAPTING AN AUTOMATIC SCREW MACHINE TO ACHIEVE COMPUTER NUMERIC CONTROL

摘要

A system for adapting existing conventional screw machines to be capable of computer numeric control (CNC). The system incorporates the use of a VersaCa m device (12) which replaces the turret cam of a single spindle screw machine (10). 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.
