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. 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






2. Someone who resists all technological change.






3. Mechanical efficiency is the effectiveness of a simple machine






4. A measure of the degree of increase in dimensions when an object is heated. This can be measured by an increase in length - area or volume. The expansivity can be measured as the fractional increase in dimension per kelvin increase in temperature.






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






6. A volume production process involving machines controlled by computers






7. Fabric with technology enhanced performance used in smart clothing - for example - enhanced stain resistance - breathability or incorporating input sensors






8. 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

13. The creation of new - modified or updated products aimed mainly at a company's existing customers.






14. An anatomical 3D model of the human body






15. An organic compound that contains aliphatic hydrocarbons - essential for the structure and function of living cells. examples include fats - waxes and steroids






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






17. 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






18. The reconstruction or renewal of any part of an existing structure or device.






19. 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






20. The difference in electrical potential between two points.






21. The property of being biologically compatible by not producing a toxic - injurious or immunological response in living tissue






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






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






24. Designing a product so that when it becomes obsolete it can easily and economically be taken apart - the components reused or repaired - and the materials recycled






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






26. 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)






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






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






29. 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.






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






31. An isometric drawing of an object with more than one component that depicts how the parts of assemblies fit together






32. The rate of flow of electrons






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






34. 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






35. 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






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