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 depositing molten material in a series of layers






2. Mechanical efficiency is the effectiveness of a simple machine






3. Someone who resists all technological change.






4. Automated machines that require data to be inputted manually by a trained operator






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






6. Hypersensitivity to dietary substances






7. Finding new applications for different products - thereby opening up new markets






8. Natural compounds formed through geological processes






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






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






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






12. Someone who immediately welcomes a technological change.






13. 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






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






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






16. 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






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






18. Where the impetus for a new design emanates from a technological development.






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






20. Obtaining users' responses.






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






22. The ability to link graphic screens together in such a way as to simulate motion or process






23. The relationship between what something - for example - a product - is worth and the cash amount spent on it.






24. Involved in development systems to ensure that products or services are designed and produced to meet or exceed customer requirements and expectations.






25. Increased body weight in relation to height - when compared to some standard of acceptable or desirable weight. a body mass index of more than 25 is defined as overweight by the World Health Organization. overweight may or may not be due to increase






26. The process of recovering the information contained - for example - in the human voice - which had been previously added to a suitable electromagnetic carrier






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






28. Analysing a situation that would benefit from redesign - and working out a strategy for improving it






29. A computer- based machine or robot that has the ability to learn from information gained through feedback






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






31. The mass per unit volume of a material






32. A realistic picture of the final model - offering some machining data - but containing no data about the interior of the part.






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






34. The reduction of weight and ise of materials






35. 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






36. A series of flat views of an object showing it exactly as it is in shape and size






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






38. 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






39. X -Y -Z plus additional rotary motion e.g. Lathe with milling head






40. A computer program that attempts to simulate an abstract model of a particular system






41. 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.






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






43. A volume production process involving machines controlled by computers






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






45. 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






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






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






48. Long- term aims and objectives of a company and ways of achieving them by allocation of resources






49. A natural resource that cannot be re- made or re- grown as it does not naturally reform at a rate that makes its use sustainable - for example - coal - petroleum and natural gas






50. 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
