ABSTRACT:
A complete Direct Digital Numerical Control (DDNC) automation system for a practical measurement system for a manufacturing process where a given slide or ram is moved under power by input of GO-TO location commands to cause a cascade of motion events to an approximate position, then relax, as a low-cost precision lock system completes the power move into exact absolute final position. This low-cost system uses simple switches & drive systems to operate without computer micro-processor (CNC) or program-logic-controllers (PLC), yet provide accurate final positioning. Position commands are simple real number digits meaningful to the Operator in work-station terms. Add-on Digital Readout Displays (DRO) are optional, as is remote input by other digital programs to augment the simple manual control panel GO-TO commands. This system is engineered for small shops in rural communities; for affordable automation of tiny devices; machines; & even provide numerical control (DDNC) for monster-machines.
