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 angle of taper - expressed in degrees (usually 5






2. The synergistic merging of nanotechnology - biotechnology - information and communication technologies and cognitive science






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






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






5. Designers design specifically for optimum use of existing manufacturing capability






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






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






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






9. 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






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






11. The cost required to maintain or repair a product or system.






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






13. A flexible computer- operated machine that is able to perform a range of tasks in an efficient and accurate manner






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






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






16. 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






17. Small changes to the design of a product that seem trivial but the cumulative effect of which over a longer period can be very significant






18. The ability of a material to be drawn or extruded into a wire or other extended shapes






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






20. The direct introduction to molten plastic under pressure into a die - which then cools rapidly - allowing the formed object to be released from the mould






21. The simplest form of carbohydrate - consisting of one sugar residue. they are the building blocks for disaccharides and polysaccharides






22. 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






23. The use of computers to aid the design process






24. Involving the use of sense organs






25. Someone who needs some convincing before embracing technological change.






26. 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






27. 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






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






29. The reduction of weight and ise of materials






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






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






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






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






34. 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






35. A style or trend






36. Costs that vary with output - for example - fuel or raw materials.






37. Houses and offices designed to function like living organisms - specifically adapted to place and are able to draw all their energy and water from surrounding sun - wind and rain






38. An anatomical 3D model of the human body






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






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






41. Excessively high amount of body fat in relation to lean body mass. a body mass index of more than 30 is defined as obese by the World Health Organization






42. 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






43. A plant or animal in which the DNA has been altered through the insertion of genetic material from another source. genetic modification is the most often used in agricultural crops to increase the resistance to herbicides or to engineer pesticides in






44. Attribute listing identifies the key attributes of a product or process and then enables designers to think of ways to change - modify or improve each attribute
