QUESTION 2
A material is required for a new product with fixed
geometry that will be shaped by moulding. The
product should be cheap to make, easily recycled
and needs reasonable strength. What type of
material would you choose for the product and
why?
For the toolbar, press ALT+F10 (PC) or
ALT+FN+F10 (Mac).
There are several ways of shaping plate or sheet glass. Name and briefly describe one of them.
Which of the following is a suitable process for creating a hollow 3D shaped component?

The moulds are made from hardened tool steel due to its high wear and abrasion resistant properties. When hardened, it will offer a hardness in the range 55-62 HRC, however it is machinable in the annealed condition. The first step to machine one of the components of a particular mould involves a milling operation. Specifically, this consists of a face milling operation which is performed on the top surface of a rectangular tool steel workpiece which is 315 mm long, 70 mm wide and 30 mm thick. To mill this component, the machinist has decided to: use a cemented carbide tool that has 5 teeth and a diameter of 80 mm. set up the machine and workpiece so that the cutter follows a path that is centred over the workpiece with a roughing depth of cut value of 4 mm. In addition, to select the relevant processing parameters, the machinist has to refer to the relevant data provided in a handbook by…arrow_forward
