Computer Integrated Controller for Numerically Controlled Machines
and Process Tools

      Disclosed is an Integrated Machine Controller for Numerically
Controlled Machines and factory process equipment.  The Computer

Integrated Controller is a system that enables a manufacturing
organization to precisely control Processes and factory equipment
while providing the factory floor and management with real-time
information regarding manufacturing logistical information.

      The Computer Integrated Controller can be used on production
equipment such as: Drillers and Routers, Milling and Boring Machines,
Automatic equipment running either a closed or open loop positioning
system, Automated Plating and chemical process equipment.

      The System consists of a PS/2* driving a VME Rack** an
Intelligent Fast Motor Control Unit* (IFMCU) rack, and an Industrial
Input Output unit (I3O***) which adapts all machine and or Process
Sensors to the Integrated System.

      The Integrated Controller provides a system for machine
control, monitoring, adaptive machine control, statiscal process
control, factory floor logistics, manufacturing volumes, yields,
defect tracking, maintenance activities and the passing of this
information to a factory's mainframe/host computing systems for later
analysis.

      Machine control, monitoring and adaptive controlling is
provided by using air and fluid temperature, flow and pressure
sensors.  Soft and hard failure limits are established.  When soft
limits are reached which are not endangering the equipment and or
process the controller will adapt to the change by modifying its
output to the machine thereby correcting the situation.  A record is
made of all modifications for later analysis.

      Statiscal Process Controls are simplified by the PS/2 based
hardware which permits linking (via LAN) to an on-line Data system
such as ETSS (Enhanced Technical Support System, Copyright IBM).

      Factory floor logistics and information such as volumes,
yields, scrap data and analysis, manufacturing materials usage and
forecasting, product tracking, floor communications and expert
systems are integrated into various software modules to reduce
manufacturing paperwork while increasing availability of information
and daily reporting.

      The Computer Integrated Controller for Process Tools consists
of the Application and Integration of the following Hardware and
Software:
