Advanced Manufacturing Techniques

Subject : engineering
Instructions:
  • Answer 20 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. Forcing molten metal under high pressure into a mold cavity






2. The direct introduction of molten plastic under pressure into a die - which then cools rapidly - allowing the formed object to be released from the mould.






3. The process of welding plastic workpieces together






4. The angle of taper - expressed in degrees (usually 5-7) - given to the sides of the forging and the side walls of the die impression






5. A type of fastening that is not supposed to be removed. It is only possible to remove such joins by drilling - cutting or grinding the join away






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






7. A sheet of plastic is heated to a forming temperature - stretched onto or into a single- surface mold - and held against the mould by applying vacuum between the mould surface and the sheet






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






9. The passage through which a liquid material flows into a die - where it solidifies to form parts






10. Completely mechanical solid- phase process in which heat generated by friction is used to create the ideal conditions for a high- integrity welded joint between similar or dissimilar metals






11. Process of creating many hollow items






12. Method of molding material - generally preheated is first placed in an open heated mould cavity (thermosetting plastics)






13. Fabrication technique for creating composite material structures (fishing rod - rowing oars)






14. A substance that is applied between two surfaces in order to bond them together






15. A process of using a two- sided mould set that shapes both surfaces of the panel (large products - top- quality - clean production - low cost - laminated curved furniture)






16. A short length of extruded pipe for use in blow moulding






17. Fibreglass continuous strand mat and/or other fabrics such as woven roping are manually placed in the mould. each ply is sprayed with catalysed resin and the resin is worked into the fibre with brushes and rollers to wet- out and compact the laminate






18. A replica is made from the artists original by way of a mould produced using wax and plaster of paris






19. Process by which hollow plastic parts are formed






20. Carried out on an open mould - where both the resin and reinforcements are sprayed directly onto the mould (pleasure boats - swimming pools)
