Lesson 1.1 Key TermsTermDefinitionAGVAutomated Guided Vehicle. A computer-controlled system that uses pallets and other interface equipment to transport work pieces to NC machine tools and other equipment in a flexible manufacturing system.ASRSAutomated Storage/Retrieval System. A system that moves material either vertically or horizontally between a storage compartment and a transfer station or within a process. AutomationThe use of technology to ease human labor or extend the mental or physical capabilities of humans. CADComputer Aided Design. The use of computers in converting the initial idea for a product into a detailed engineering design. CAMComputer Aided Manufacturing. The use of computers in converting engineering designs into finished products. CIMComputer Integrated Manufacturing. A company-wide management philosophy for planning, integration, and implementation of CComputer Numerical Control. A numerical control method in which one computer is linked with one machine tool to perform NC functions.Dependent VariableA variable whose value depends on the value of another variable.FMSFlexible Manufacturing System. A flexible group of CNC machine tools that are highly automated and integrated capable of producing a family of parts.Independent VariableThe controlling factor between variables, on which the value of the other variable depends. JITJust in Time. A system that eliminates work-in-process (WIP) inventory by scheduling arrival of parts and assemblies for an operation at the time they are needed and not before.KaizenContinuous improvement that involves all participants.Lean ManufacturingThe systematic elimination of waste.ManufacturingA series of interrelated activities and operations that involve product design and the planning, producing, materials control, quality assurance, management, and marketing of that product.Mass ProductionA manufacturing process that can include specialized and single-purpose machines to produce a great many identical parts.PLCProgrammable Logic Controller. A solid-state control system that has a user-programmable memory to store instructions.RoboticsThe science and technology of robots, their design, manufacture, and application.Six SigmaA highly structured methodology that incorporates techniques and tools for eliminating defects and variability from a process. To achieve Six Sigma, a process must not produce more than 3.4 defects per million opportunities.WIPWork-in-Process. Materials or parts that are actually being processed into final products.WorkcellA manufacturing unit consisting of a group of work stations and their interconnecting materials-transport mechanisms. ................
