The specifications and constraints are somewhat overlapping for this project. The most critical constraint is the amount of material available for the project. I plan on machining two tools out of billet 2024 T6 Aluminum plot stock; the material I have is 3/4″ thick and I would like to utilize as much thickness as possible to maintain torsional stiffness. The second constraint is using Petzl picks and their mounting interface, this will make the tools much more usable and easy to replace parts on because I won’t need to make them myself. There is also a creative aspect to this which is more of a specification than anything, I want the shape to be elegant, organic, and ergonomic. The last constraint is time, the machine time alone is estimated to be about 10hrs per tool which doesn’t sound like a lot but in terms of machining it is a multi-day affair per. There are probably more specifications and constraints that are apart of this project but I don’t think they are as high on my list as the aforementioned.
