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 manufacture of 3D parts by removing (cutting) unwanted material from a block






2. An adhesive is a substance that is applied between two surfaces in order to bond them together






3. Designing in a way that takes account of the environmental impact of the product throughout its life






4. 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






5. A solution to a problem in one field is used to provide a new idea for a design problem in another






6. The costs that must be paid out before production starts - for example machinery. these costs do not change with the level of productions






7. The biological value of a protein refers to how much of the nitrogen content of food is retained by the body. the biological value of proteins ranges from 50% to 100% and is a measure of how much dietary protein source can support growth






8. The rate of flow of electrons






9. The research and analysis of the mechanics of living organisms






10. 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






11. 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






12. Refers to materials and devices that operate at the nanoscale. 'Nano' means a billionth. A nanometer is one- billionth of a meter






13. A volume production process involving machines controlled by humans






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






15. An evaluation of the actual performance of the task or learning objective using the conditions under which it will be performed and the absolute standard for acceptable performances






16. The permanent deformation of a solid subjected to stress






17. The production of large amounts of standardized products on production lines - permitting very high rates of production per worker






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






19. A material made up of a network of natural or artificial fibres formed by knitting - weaving or pressing into felt






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






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






22. This is a measure of a material's ability to conduct electricity. a material with low electrical resistivity will conduct electricity well.






23. Using creative ability to produce a wide range of possible solutions to a problem






24. 3 linear axes (X -Y -Z) and two rotary axes (A -B) e.g. milling machine






25. A 3D drawing that realistically represents an object by utilizing foreshortening and vanishing points (usually imaginary ones)






26. A style or trend






27. The class of materials that are continuous filaments or are in discreet elongated pieces - similar to lengths of thread with a length to thickness ratio of at least 80






28. The initial impetus for the development of a new product is generated from a demand from the market






29. A brand is a product from a known source (organization). the name of the organization can also serve as a brand






30. Pleasure derived from the sensory organs - including pleasures connected with touch - taste - smell and sensual pleasure






31. A small- scale production process centred on manual skill






32. Water that contains animal - human or food waste and would not be reused for other purposes






33. 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.






34. Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.






35. The application of methods and systems found in nature to the study and design of engineering systems and modern technology






36. The exterior surface of a building's construction: the walls - windows - roof and floor. also referred to as 'building shell'






37. An anatomical 3D model of the human body






38. Waste water generated from processes such as washing dishes - bathing and laundry






39. Reuse of a product in the same context or in a different context.






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






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






42. The way a person or group lives - including patterns of social relations - consumption - entertainment and dress






43. Designing in relation to materials during processing






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






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






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






47. The ability to simulate a real situation on the screen and interact with it in a near- natural way.






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






49. A situation where the firm does not allocate space to the storage of components or completed items - but instead orders them (or manufactures them) when required. large storage areas are not needed and items that are not ordered are not made
