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. The feed speed is the rate at which the cutting tools moves in x - y and z paths






2. Tool path is determined by individual Z coordinates across the product






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






4. Where a completely new product is devised by going back to the roots of a problem and thinking about a solution in a different way.






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






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






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






8. An adverse food- induced reaction that does not involve the immune system






9. Computer simulation of a variety of mechanical and biological aspects of the human body






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






11. A measurement of the relative percentages of fat and muscle mass in the human body - in which weight in kilograms is divided by height in metres and the result used as and index of obesity






12. The exposure of protein to heat or acid - which results in irreversible changes that reduce solubility and change optical characteristics






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






14. Fabric with technology enhanced performance used in smart clothing - for example - enhanced stain resistance - breathability or incorporating input sensors






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






16. A type of fastening that is not supposed to be removed. it is only possible to remove such joins by drilling - cutting or grinding the join away






17. The process of adding the information contained - for example - in the human voice to a suitable electromagnetic carrier






18. The wide acceptance (and sale) of a product






19. A filamentous material long in relation to its width/breadth






20. The manufacture of 3D parts by depositing molten material in a series of layers






21. A sophisticated CIM system that manufactured products to individual customer orders. the benefits of economy of scale are gained whether the order is for a single item or thousands






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






23. An isometric drawing of an object with more than one component that depicts how the parts of assemblies fit together






24. A group of products having common classification criteria. Members normally have many common parts and assemblies.






25. The passive solar practice of placing windows - or other transparent media - and reflective surfaces so that - during the day - natural sunlight procivides effective internal illumination






26. The use of computers to aid the design process






27. Designing a product so that when it becomes obsolete it can easily and economically be taken apart - the components reused or repaired - and the materials recycled






28. Involves a company both in the development of new products and in selling those products to new companies






29. Flexible designs that can be adapted to changing technical and market requirements.






30. Z axis for depth - X and Y for direction of cut e.g. milling - routing - engraving






31. Fatty acids are carboxylic acids with a long hydrocarbon chain - usually straight






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






33. Morphologic synthesis is an elaboration of attribute listing. after completing the list of attributes - list them along two sides of a 2D grid. think creatively about how the attributes can be developed through new ideas in each of the cells to impro






34. Someone who immediately welcomes a technological change.






35. 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






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






37. Low levels of food intake - which can be transitory (as a result of crisis) - seasonal or chronic (when it occurs on a continuing basis)






38. A technique that uses a fluid support structure that can be washed and drained away. Used for more intricate internal construction where it would be difficult to break away supports.






39. The opposition that a substance offers to the flow of electric current.






40. Excess material on a moulded part - forming a thin fan where two parts of the mould meet






41. Obtaining users' responses.






42. The ability of a material to resist the propagation of cracks.






43. That proportion of a population with a dimension at or less than a given value






44. A device that is able to laser cut and engrave 2D shapes






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






46. A conscious act either to ensure a continuing market or to ensure that safety factors and new technologies can be incorporated into later versions of the product






47. Pleasures derived from satisfying peoples taste - values and aspirations






48. 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






49. Fatty acids that are required in the human diet. this means that it cannot be synthesized by the body from other fatty acids and must be obtained from food.






50. In chemistry - an amino acid is any molecule that contains both amino and carboxylic acid functional groups. in biochemistry - this is shorter and more general term is frequently used to refer to alpha amino acids in which the amino and carboxylate f
