Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A situation where a company keeps a small stock of components (or complete items) or ones that take a long time to make - just in case of a rush order






2. Designing taking account of assembly at various levels - for example - component to component - components into sub- assemblies and sub- assemblies into complete products






3. The assessment of the effect a product has on the environment from the initial concept to disposal






4. A functional prototype - or a functional appearance model - is a prototype that 'looks like' and 'works like' a production product. although they are made from prototype materials - these models simulate actual finishes and colours as well as mechani






5. The incorporation of gas into a food product. it may be air - which is often beaten in - or carbon dioxide - which can be introduced under pressure (for example - to aerated water) or by the action of yeast (for example - in bread)






6. A compound that cannot be made in the body but has to be provided ready- made in the diet - for example - vitamins - essential fatty acids - and essential amino acids






7. This covers all activities from design to documentation. It also includes the regulation of quality of raw materials - assemblies - products and components - services related to production - and management and inspection processes.






8. X and Y axes for cutting e.g. CNC Lathe






9. Coordination - based code that also includes feed speed and stop/start






10. All aspects of the processing - preparation - storage - cooking - and serving of food to make sure that it is safe to eat






11. Applies to 3D profiling. it is the amount of tool that passes over work already cut and determines the quality of the finished surface. it is expressed as a percentage - the higher the quality the higher the percentage






12. Refers specifically to the computer control of machines for the purpose of manufacturing complex parts in metals and other materials. Machines are controlled by a program commonly called a 'G code'. Each code is assigned to a particular operation or






13. A form of group think. a group with a recommended size of 10-12 people first devises wild ideas - all of which are written down. no criticism or evaluation is allowed until this is finished - as it is impossible to be creative and critical at the sam






14. Sliced CAD data and cuts each layer from a roll of material using a laser or plotter cutter. Sliced layers are glued together to create model.






15. A short length of extruded pipe for use in blow moulding






16. An appearance prototype or appearance model is a physical representation of an object that literally appears like the production product. However - it does not function and is made from wood - foam - clay or other prototyping materials






17. The property of being biologically compatible by not producing a toxic - injurious or immunological response in living tissue






18. 3D printing process using a vat of photosensitive resin and a vertically moving platform. Laser beam directed onto surface of resin to print patter of current model's layer by hardening resin. Platform then moves down by a layer thickness so the next






19. A mixture that contains at least one metal. this can be a mixture of metals or a mixture of metals and non - metals






20. Lack of essential vitamins and minerals resulting from unbalanced food intake and specific problems of food absorption






21. A system of manufacturing that uses computers to integrate the processing of production - business and manufacturing in order to create more efficient production lines






22. A specific manufacturing term - sometimes relating to one material group only






23. The completeness and accuracy of a data set that is being used to inform a design decision






24. The range of users for a particular product or system.






25. The business of putting an invention in a market place and making it a success






26. Employs inkjet technology. Linear array of nozzles deposit molten wax on a platform layer by layer to build a 3D model.






27. Limited volume production (a set number of items to be produced)






28. A technique that uses break- away supports. Break- away structure can be difficult to remove from detailed areas.






29. The use of the suns energy to heat up water and air directly






30. The formation of a gel by using gelatin or by the heat treatment of starch and water to break open starch granules - for example custard






31. Designing to enable the product to be manufactured using a specific manufacturing process - for example - injection moulding






32. Representative users perform realistic tasks by interacting with a paper version of the user- product interface that is manipulated by a person acting as a computer - who does not explain how the interface works






33. The design contains those implicit features of a product that are recognized as essential by a majority of manufacturers and purchasers






34. Clear representations of the final part. They provide a complete set of data for the product to be realized.






35. A product development process obtained through 3D - parametric and associative CAD systems. The main feature of this new method is that the design originates as a concept and gradually evolves into a complete product consisting of components and sub-

36. An influential individual - usually working within an organization - who develops an enthusiasm for a particular idea or invention and 'champions' it within that organization.






37. Two or more atoms that are normally bonded together covalently






38. The transfer of an idea from one context to another






39. A tool used in the manufacture of parts by moulding - forging - swaging or stamping processes






40. A 3D representation of an object drawn with the horizontal plane at 30






41. A volume production process involving machines controlled by humans






42. A measure of how fast heat is conducted through a slab of material with a given temperature difference across the slab.






43. The ability to analyse information in order to select an answer from alternatives






44. The mass production of a product via a flow line based on the interchangeability of parts - pre- processing of materials - standardization and work division






45. CO2 laser is used to sinter a thin layer of heat- fusible powder that gradually builds up the 3D model.
