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. The technique of heating and cooling a building naturally without the use of mechanical equipment






3. A measure of how fast heat is conducted through a slab of material with a given temperature difference across the slab.






4. 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






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






6. 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






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






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






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






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






11. A sugar (a carbohydrate) composed of two monosaccharide molecules






12. 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






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






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






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






16. Natural compounds formed through geological processes






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






18. Technology appropriate to the context in which it is applied. appropriate technologies are low in capital cost - use local material wherever possible - create jobs using local skills and labour - involve decentralized renewable energy sources - make






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






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






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






22. A condition whereby users perceive more aesthetically pleasing designs to be easier to use than less aesthetically pleasing designs






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






24. A 3D representation of an object drawn with the horizontal plane at 30






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






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






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






28. This is the factor in which the machines multiplies the force put into it






29. 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






30. The resistance of an elastic body to deflection by an applied force.






31. 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






32. A volume production process involving machines controlled by humans






33. The observation of people using a product and collection of comments from people who have used a product.






34. A model using mathematical symbols that can be manipulated numerically






35. The calculation and simulation of unknown factors in products using CAD systems. for example simulating the stresses within a welded car part






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






37. 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-


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






39. The use of consumer reports and newspaper items to follow historical development. useful sources of information could include CD-Roms - such as encyclopedias and newspapers - or more specific discs - subject specific magazines - and manufacturers' in






40. A designer creates a part geometry independent of the assembly or any other component. although there are often some design criteria established before modelling the part - this information is not shared between models. once all part models are compl


41. 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






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






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






44. Designing in relation to materials during processing






45. 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
