CNC machining costs are rarely the result of a single variable. As the sections above demonstrate, material selection, part design complexity, setup and tooling investment, and production volume each contribute independently to the final cost of a machined component, and their interactions compound quickly when multiple cost drivers are present simultaneously.

Strong DFM protects product performance while removing avoidable machining cost, setup complexity, and inspection risk.

The best CNC machining tolerance is not the smallest number on the drawing. It is the tolerance that allows the part to function correctly while staying manufacturable, measurable, repeatable, and cost-effective.
