Which statement best describes a design for manufacturability (DFM) consideration?

Maximizing the number of steps

Using only custom tooling

Extensive rework

Choosing easy-to-machine features and minimizing special setups

DFM is about designing parts so they can be produced quickly, reliably, and at lower cost. Choosing features that are easy to machine and minimizing the need for special setups fits this idea because it lets you use standard tooling, reduces setup time, and lowers the chances of errors or delays in production. This leads to simpler processes, fewer issues, and cheaper manufacturing overall.

The other options would raise costs and complexity: more steps mean more time and resources; relying on custom tooling adds expense and limits flexibility; and lots of rework signals design choices that don’t support efficient manufacturing.
