AnswersOne off production Also referred to as job production and related to ‘tailor- made’, bespoke or customised solution.Batch production Identical products in specified, predetermined numbers, which can vary from tens to thousands.Mass production Makes use of efficient automated manufacturing processed and a largely unskilled workforce.Continuous production Used to manufacture standardised mass-produced products that meet every day mass-market demands.Lean manufacturing and Just in time (JIT) Manufacturing where there is no ‘fat’. Key feature is the notion of JIT. Provide techniques that ensure minimum waste is incurred during production and produce when needed.Advanced manufacturing technology Describes the significant impact of computers on manufacturing. Led to(AMT) the development of CAD, CAM, robotics, materials handling devices and CIM that have increased the accuracy and flexibility of the manufacturing process.Quick response manufacturing (QRM) Requires a manufacturer to move from traditional batch production to ‘flow’ production. Triggered by consumer demand and not based on complex demand forecasts. Manufacturer can quickly response to fluctuations in the economy and ever-changing market demands.Concurrent Manufacturing Systematic approach to the integration of design, manufacture and related processed where all life cycle stages of the product are considered simultaneously.Flexible manufacturing systems (FMS) A form of flexible automation in which several machines are linked together by a material-handling system, with all aspects controlled by a central computer.
AnswersComputer integrated manufacture (CIM) Takes FMS a step further by bringing together all aspects of a company’s operations. All teams can share the same information and communicate with one another.Product Data Management (PDM) An information system used to manage the data for a product as it passes from design to manufacture, it ensures that changes are made to one database.Enterprise resource planning system (ERP) Integrate all departments and data across a company onto a single computer system that can serve all of those departments’ particular needs by using a unified databaseFlexible manufacturing cells A group of workstations, machines or equipment arranged such that a product can be processed progressively from one workstation to another without having to wait for a batch to be completed and without additional handling between operations.Computer aided quality control systems Achieved within a manufacturing cell using a coordinate measuring(CAQ) machine (CMM) for extremely accurate dimensional measurement.Automated materials handling system Provide transportation and storage of materials, components and assemblies.Automated storage and retrieval systems Automated robotic system for sorting, storing and retrieving items in a(ASRS) warehouse. Within CIM a computer controls the transportation of materials and components to the required points.Automated guided vehicles (AGV) Small, independently powered vehicles that are usually guided by radio frequency wires that are buried in the floor, or use optical sensors in a laser-guided navigation system.
ActivityIn groups, use the worksheetto analyse the product andcomponents of the productaccording to the:• Scale of production it fits into• The manufacturing system/s that were used to produce it
ActivityIndividually, design and explain (usingannotations) how you could adapt this productto make it a one-off product. Explain the difference of this one-off product that you have designed compared to the one bought in a store.
