We've already ruled out machining on cost grounds. This is about as much as we can do to reject processes for simple technical reasons, all that remains is to think about the processing cost. These requirements for the plug pin are not very demanding - so we can do little to reduce our list of processes further.
The next stage is to think about dimensional tolerances, surface finish, quality etc. So by referring to further process infomation (available elsewhere on this Finish and quality We have a small component which is essentially '2D'. In addition, factors such as symmetry and concave curves will affect which processes can be used successfully. 3D - with a complex geometry such as an engine block.2D - components with the same cross-section all the way through - which may be short things like plug pins, or long things like window frames.Folded or drawn sheet, such as a can or microwave casing.With metal parts, it is useful to think of the basic shape, as further steps such as drilling can be used later to produce specific "features" such as holes.
The shape of a component is often key to selecting a suitable process. The next stage is to think about size and shape. Unfortunately this does not help us much in choosing a suitable process! One of the advantages of metals is that they can be processed in many ways. It would also be possible to use machining to make the pins, but even at this stage we can reject this as being too expensive as there are plenty of other options. Clearly the metal shaping processes are of most interest and the main ones are tabulated opposite. The first step is to consider which processes are suitable for use with brass.
So let's start with material compatibility<. Case Study - 13A plug Plug pins: selecting the process The plug pins are made out of brass, but how are they manufactured? The selection of a suitable process involves several stages here we will follow the approach taken in the tutorial.
