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 specific manufacturing term - sometimes relating to one material group only






2. 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.






3. 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






4. Rebuilding a product so that it is in an 'as new' condition - and is generally used in the context of car engines and tyres.






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






6. Apply technologies to improve the building environment and functionality for occupants and tenants while controlling costs to improve end- user security - comfort and accessibility and help user productivity






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






8. Using the materials from obsolete products to create other products.






9. The process of discovering a principle. a technical advance in a particular field often resulting in a novel product






10. 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






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






12. 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)






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






14. Involving the use of sense organs






15. A volume production process involving machines controlled by humans






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






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






18. The spontaneous representation of ideas on paper without the use of technical aids






19. An emerging technology that interfaces the user via the sense of touch






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






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






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






23. 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






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






25. Mechanical efficiency is the effectiveness of a simple machine






26. The aspect of ergonomics that deals with body measurements - particularly those of size - strength and physical capacity






27. Basically a CNC robot with small extrusion head. Moves back and forth along a platform building up a model by feeding heated plastic wire through the head.






28. Obtaining users' responses.






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






30. The number of bits per second produced by a digital system






31. An anatomical 3D model of the human body






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






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






34. 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






35. The recording of human or animal movement by any means - for example - by video - magnetic or electro- mechanical design






36. 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






37. The angle of taper - expressed in degrees (usually 5






38. The width of the electromagnetic spectrum that a signal occupies






39. 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-

44. Resources that are naturally replenished in a short time.






45. 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






46. 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.
