cIm -IE775 What is the Manufacturing Enterprise? An Enterprise is a complex system of cultural, process, and technology components a system engineered to accomplish organizational goals. Enterprise

cIm -IE775 Enterprise Representation The Enterprise is a system that has certain fundamental processes. Acquire resources Manage financial assets Acquire resources Manage financial assets Set direction Acquire customers Develop product and process Fulfill orders Support customer and product Acquire customers Develop product and process Fulfill orders Support customer and product Enterprise

cIm -IE775 Integration  Legacy systems - existing systems (many times not built for integration)

cIm -IE775 Ch 3 - The Computing System

cIm -IE775 CAD  CAD (Computer Aided Design) or Computer Aided Design & Drafting (CADD) operators use mainframes/minis/workstations/micro-computer systems to engineer and design complex parts in today's manufacturing environment.  Prior to the 1980's, draftsmen used drawing boards, T Squares and a plethora of tools to draw blueprints manually  Now, blueprints, models and complete engineering designs are created on personal computers, workstations and networked computer terminals. Thus the need for manual drawings, pasted-on modifications and such have been replaced by the superior results achieved by the use of CAD systems

cIm -IE775 CIM  CAM (Computer Aided Manufacturing) systems are used in all modern manufacturing workplaces to model parts being constructed in machining operations and design processes, not only for modeling purposes but for design and quality assurance purposes as well!  CAM systems are used for determining the accuracy of design prior to manufacturing.  Models can be checked for diameters, wall thicknesses, stress analysis, clearances and many other features determined to be critical before the initial workpiece is ever constructed, thus eliminating unnecessary production cost as well as reducing the time it takes to produce the part.  CAM systems are used to generate the CNC toolpath programs used in machining the actual workpieces. The great majority of machining done today is done on CNC controlled machines and involve the end products designed on CAM systems.

cIm -IE775 CNC  CNC ( Computerized Numerical Control) machines are designed to accurately produce machined parts at a higher rate of speed than manually machined parts and with much greater repeatability.  Like CAD and CAM, CNC machines are related through their use of the Cartesian Coordinate system.  Both milling and turning is nearly all done on Computerized Numerically Controlled machines
