A process is the means whereby a workpiece is made. There are essentially three classes of process. The first is where the starting point is a piece of metal. Some of this is removed in order to get towards the required part. This includes most common machining processes such as turning and milling but also where one piece of metal is separated into two parts. The second class is where one piece of metal is added to. The third class is where the piece of metal does not really change in volume but changes in it shape.
