7. SLS selective laser sintering Selective laser sintering is an additive rapid manufacturing technique that uses a high power laser (for example, a carbon dioxide laser) to fuse small particles of plastic, metal, or ceramic powders into a mass representing a desired 3-dimensional object. The laser selectively fuses powdered material by scanning cross-sections generated from a 3-D digital description of the part (for example from a CAD file or scan data) on the surface of a powder bed. After each cross-section is scanned, the powder bed is lowered by one layer thickness, a new layer of material is applied on top, and the process is repeated until the part is completed

8. Stereo lithography Stereo lithography is a common rapid manufacturing and rapid prototyping technology for producing parts with high accuracy and good surface finish. A device that performs stereo lithography is called an SLA or Stereo lithography Apparatus. Stereo lithography is an additive fabrication process utilizing a vat of liquid UV-curable photopolymer "resin" and a UV laser to build parts a layer at a time. On each layer, the laser beam traces a part cross-section pattern on the surface of the liquid resin. Exposure to the UV laser light cures, or, solidifies the pattern traced on the resin and adheres it to the layer below

9. CAD to RP To get the idea prototyped requires one other piece of software: Autocad  slice  SLA The slice software takes the design and cuts it in to thin layers so that each layer can be processed in turn by the SLA or LS process.

11. CNC The abbreviation CNC stands for computer numerical control, and refers specifically to a computer "controller" that reads G-code instructions and drives a machine tool, a powered mechanical device typically used to fabricate components by the selective removal of material.G-codemachine tool CNC does numerically directed interpolation of a cutting tool in the work envelope of a machine. The operating parameters of the CNC can be altered via a software load program.

14. CIM Computer-integrated manufacturing (CIM) is a method of manufacturing in which the entire production process is controlled by computer. Typically, it relies on closed-loop control processes, based on real-time input from sensors. It is also known as flexible design and manufacturing.

16. A CIM system is not the same as a "lights out" factory, which would run completely independent of human intervention, although it is a big step in that direction. Part of the system involves flexible manufacturing, where the factory can be quickly modified to produce different products, or where the volume of products can be changed quickly with the aid of computers.

17. CIM Some or all of the following subsystems may be found in a CIM operation: CAD/CAM (Computer-aided design/Computer-aided manufacturing) CAPP, (Computer-aided process planning) ERP (Enterprise resource planning)Enterprise resource planning CNC (computer numerical control) machine tools DNC, direct numerical control machine toolsdirect numerical control FMS, flexible machining systems ASRS, automated storage and retrieval systemsautomated storage and retrieval systems AGV, automated guided vehiclesautomated guided vehicles Robotics Automated conveyance systems Computerized scheduling and production control CAQ (Computer-aided quality assurance)Computer-aided quality assurance A business system integrated by a common database. Lean Manufacturing

18. SPC Statistical Process Control (SPC) is an effective method of monitoring a process through the use of control charts. Control charts enable the use of objective criteria for distinguishing background variation from events of significance based on statistical techniques. Much of its power lies in the ability to monitor both process centre and its variation about that centre, also known as a setpoint.control charts

19. SPC By collecting data from samples at various points within the process, variations in the process that may affect the quality of the end product or service can be detected and corrected, thus reducing waste as well as the likelihood that problems will be passed on to the customer. With its emphasis on early detection and prevention of problems, SPC has a distinct advantage over quality methods, such as inspection, that apply resources to detecting and correcting problems in the end product or service.

20. SPC – PID curves Overshoot Acceptable response Undershoot This could be graph of temperature of a furnace, for example. The Blue is the desired response and the green is the actual. However if the control system is not setup correctly you can get overshoot or undershoot

21. Concurrent Engineering A system of design that organises tasks in parallel. Any changes made to one CAD file will be accessible by all. AND If the changes affect any other files they will automatically update as well. For example, consider designers of a CAR working in various countries of the world on various different tasks.
