- Question 2 Blitz Precision Engineering Ltd manufactures moulds for injection moulding machines. 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…Which three of the following are basic bulk deformation processes in metal forming: forging bar drawing extrusion stamping blanking deep drawingIn which of the following forming operations, the workpiece is pulled through a die resulting in reduction of area? a.
