Question

Question 1 (30 points You are required to state and describe which manufacturing processes to use for the manufacture of the shown part. This may include more than one manufacturing process (primary step and then one or more secondary steps). Study the shape carefully and consider all acceptable options to achieve the final shape given. The part is made of a brass alloy and its largest diameter is 30 cm, with a weight of 17 kg. Suu A. [10 marks] State which manufacturing processes are necessary to manufacture the given part? Which process should be first, which should be second and if you need more than two then state the processes in the logical order? You must be specific of which process in particular to use (for example do not say machining die casting, or forging...but you need to specify which machining operation, which diecasting operation, or which forging operation to use, and so on).

Answer 1

Leb As the shape and geometry of the body Suggeris from its an intuicate one ard have complexity along with various details. Mass 17kgs. Man Dia = 50 cm we can Manufacture the specimen with following process 2 Sond Carling and Conventional Machining to close tolerances: As it is a huge machine part and heavy in weight too sord Carling coill be formourable: As sord casting need at first a Mould, which will be exact Replica of the firal product. To make the mould we con ure either wood (Carpentery), coooden Mould or BD-modeled and pointed specimen.. As the Cast is 30cm in dia, for 3D-printer to point a replica will be very corf affecting ord fime contuming. 50, would suggest to go for coooden moulds which are comporterly cheaper and less time consu consuming After the mould (Replica) is proposed Casting is been done with cope and Drag boxes ålorg.coith corrplete gating System Allow it to cool and solidify for 8-12 hr ard then go for Machining

process such 0) Now a زو As the malenal specimen produced from Card Casting are not so good with their dimensional to learces, so we need to go for various machining goirding, drilling. Reaming boring, facing et. Component is ready. After giving finishing touch our iiNon Conventional Maching / Case - Mackinting days almort all the time consumine pored production facilities are been replaced by Non-Conventional maching process such CNC, plasma Arc, EDM,ECM ete etc, To Manufacture the above specimen we need a feel Dick of required thicknes as por dimensions ord on engineer who con write various Gard M codes for CNC machining. The one great advan tege of CNC mocwthing is it is very fast ord deliven firal product to very close tolerancer. After all the required material removal the specimen may need to go for rasious heat treatment process. And now our Component is ready. There could be various other ways too for the manufacture of the above possible carperest, baudietos
