We have a large machine shop here (a small section of it actually used to be an engine reconditioning shop)
Im an engineer at an (ductile) iron foundry. I do the majority of product design, tooling, process improvement etc. so CAD/CAM is no problem
Its not cost effective to have one of our cnc's tied up doing tooling so we usually outsource that component (still trying to get my own)
