My understanding of how materials can be shaped has definitely changed since doing materials and processes and working on my projects. When I first thought of Shaping techniques I instantly thought of sawing, filing and a few other shaping by wasting techniques and didn't think of other methods which do not involve subtracting material such as heat treating and bending. I also didn't think of the various machines that can be used to shape materials particularly CNC machines which I have also made use of.
