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






2. The rate of flow of electrons






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






4. A 3D drawing that realistically represents an object by utilizing foreshortening and vanishing points (usually imaginary ones)






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






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






7. Natural compounds formed through geological processes






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






9. Tool path is circular - which is useful for round and curved objects






10. 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.






11. The ability to link graphic screens together in such a way as to simulate motion or process






12. The process of adding the information contained - for example - in the human voice to a suitable electromagnetic carrier






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






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






15. 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


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






17. The design contains those implicit features of a product that are recognized as essential by a majority of manufacturers and purchasers






18. 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.






19. 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






20. 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

22. The ability of a material to withstand pulling forces.






23. A device that is used to cut 2D shapes from card and vinyl






24. The ability of a material to resist the propagation of cracks.






25. The process of recovering the information contained - for example - in the human voice - which had been previously added to a suitable electromagnetic carrier






26. Designing in relation to materials during processing






27. A mixture that contains at least one metal. this can be a mixture of metals or a mixture of metals and non - metals






28. A sophisticated CIM system that manufactured products to individual customer orders. the benefits of economy of scale are gained whether the order is for a single item or thousands






29. The difference in electrical potential between two points.






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. In chemistry - an amino acid is any molecule that contains both amino and carboxylic acid functional groups. in biochemistry - this is shorter and more general term is frequently used to refer to alpha amino acids in which the amino and carboxylate f
