Mech-Chem Associates, Inc. engineers and designs operator interface screens to allow equipment and set point parameters to be adjusted. The chemical milling facility is reviewed and subdivided into several systems. Each system has a screen which functions as the monitoring and control point. These screens allow for viewing of equipment operation, as well as display of the alarms and set points.
