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






2. The resistance a material offers to penetration or scratching






3. Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.






4. A specific manufacturing term - sometimes relating to one material group only






5. Flexible designs that can be adapted to changing technical and market requirements.






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






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






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






9. 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)






10. A comparative measure of poverty - literacy - education - life expectancy - childbirth and other factors for countries worldwide






11. 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

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






13. 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






14. Designing taking account of assembly at various levels - for example - component to component - components into sub- assemblies and sub- assemblies into complete products






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






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






17. A situation where the firm does not allocate space to the storage of components or completed items - but instead orders them (or manufactures them) when required. large storage areas are not needed and items that are not ordered are not made






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






19. The rate of flow of electrons






20. The research and analysis of the mechanics of living organisms






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






22. An evaluation of the actual performance of the task or learning objective using the conditions under which it will be performed and the absolute standard for acceptable performances






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






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






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






26. A functional prototype - or a functional appearance model - is a prototype that 'looks like' and 'works like' a production product. although they are made from prototype materials - these models simulate actual finishes and colours as well as mechani






27. 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-

28. Fatty acids that are required in the human diet. this means that it cannot be synthesized by the body from other fatty acids and must be obtained from food.






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






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






31. 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






32. 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






33. 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






34. Natural compounds formed through geological processes






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






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






37. Markets divided up into smaller groups where the purchasers have similar characteristics and tastes






38. 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






39. Clear representations of the final part. They provide a complete set of data for the product to be realized.






40. 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.






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. The mass per unit volume of a material






43. Sliced CAD data and cuts each layer from a roll of material using a laser or plotter cutter. Sliced layers are glued together to create model.






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