Design for manufacturability (DFM) is the fastest way to cut CNC cost and lead time without giving up function. Most savings come from a handful of repeatable rules.
This guide collects those rules — wall thickness, pockets, internal corners, radii, threads, hole types and drawing formats — into one checklist.
