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






2. 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






3. Basically a CNC robot with small extrusion head. Moves back and forth along a platform building up a model by feeding heated plastic wire through the head.

6. Automated machines that require data to be inputted manually by a trained operator






7. 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






8. 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-

14. An individual (often craft- produced) article or a prototype for a larger- scale production






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






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






17. 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






18. 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






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






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






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






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






23. A sugar alcohol with three hydrophilic alcoholic hydroxyl groups. it is an important component of triglycerides (fats and oils) and phospholipids






24. The use of computers to aid the design process






25. Apply technologies to improve the building environment and functionality for occupants and tenants while controlling costs to improve end- user security - comfort and accessibility and help user productivity






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






27. A schematic representation of a process






28. Pleasure derived from people's mental and emotional reactions to a product.






29. The manufacture of 3D parts by depositing molten material in a series of layers






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






31. Analysing a situation that would benefit from redesign - and working out a strategy for improving it






32. 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
