3. Assessment revision Make sure you revise for Theory paper and Design paper Design paper – Important information One hour 15min Only answer one question (Answer the resistant materials question!!!)

8. Materials Revise physical properties and working properties and application in relation to plastics, woods and metals. Thermoplastics (nylon, polythene, polyvinyl chloride (PVC), acrylic, Polystyrene, polypropylene) Question: Give examples of products made for each thermoplastic and one of the properties that makes it a good use of material. Thermosetting plastics (polyester resin including GRP, melamine, urea, formaldehyde and phenol formaldehyde) Question: Give examples of products made from each thermosetting plastic and one of the properties that makes it a good use of material. Classification, properties and uses of natural timbers. Show a working knowledge of the following manufactured boards Plywood, blockboard, chipboard, hardboard and MDF. Question: Classification, property and use of MDF. Show a working knowledge of the following metals: Ferrous metals (mild and high carbon steels) Question: Non-ferrous metals (aluminium, duralumin and other common casting alloys, copper and its alloys, zinc, lead and tin) Question:

9. Wastage/addition and joining methods Select and perform the following forms of cutting and removal of material, and joining and adding to a material to produce the required shape, form or contour: – use hand snips, saws, files, basic planes and abrasive cutters – simple hole boring by hand or machine including pilot, clearance, tapping, countersunk and counterbored holes – use taps and dies for screw cutting by hand – use planes, chisels, gouges, saws, files and rasps – use abrasive mops, discs and belts Show tools: Pilot hole, Countersunk hole, Taps and dies - Page 64/65 Activity: Students draw isometric drawings showing how two pieces of two by one pine can be joined using – nails, screws (look at two types of screws – slot and phillips head), nuts and bolts Activity: Students draw isometric drawings showing how two pieces metal can be joined using nuts and bolts, rivets (page 71), do sketch activity. Milling machine and CNC milling http://www.youtube.com/watch?v=sxbiIpXZfG8&feature=related http://www.technologystudent.com/equip1/vert1.htm http://www.technologystudent.com/equip1/vert2.htm Question: 1. Draw a simplified diagram of the vertical miller and label all the important parts.2. Explain the need for safety when using this type of machine. You may wish to describe the type of safety clothing required.3. Describe how you could use a vertical miller in one of your projects.

10. Shaping - Deforming/reforming • understand the following processes: bending, simple casting, lamination; vacuum forming; blow moulding; injection moulding; extrusion • Show videos: • Questions: Vacuum forming • http://www.technologystudent.com/equip1/vacform3.htm • (check answers) - http://www.technologystudent.com/equip1/vacfor3b.htm

11. Case study: Cutlery tray • What forming/reforming process could be used to make this product? • What plastic would this product be made from? • Draw what the former would look like in isometric. • What material would the former be made from and why? • How would we make the former from on sheet of MDF. • List factors to consider for the former in order to have a successful vacuum form.

13. Joining and assembling methods Ways of assembling moving parts – using hinges Other examples of hinges http://www.technologystudent.com/joints/hinge1.htm Wood joints – edge joints Piano hinge Tee hinge Question: Draw the hinge types and list two products that would include each hinge. Tongue and groove joints, biscuit joints Question: Draw the edge joints and name two products that would join wood in this method

17. Special treatments • understand how the following processes can change the molecular structure of a material making it more or less suitable for the task it has to perform: – work hardening – annealing all metals – case hardening of mild steel – hardening and tempering tool steel (HCS) • Show videos:
