When machine shops see an RFQ for a rectangular part that is 2.03″ thick x 2.1″ wide and volumes are high, eyes roll back in their heads. A top-shelf designer produces part designs with boundary conditions slightly under raw stock material sizes to save significant machine time/cost for production orders; start engineering with the raw material stock size in mind from the beginning.
If volumes are north of 100, 500, or over 1000? Potentially tens of thousands of dollars in savings can be achieved, and we do the right thing by not wasting material, energy, and resources.
