Design and shop floor must agree on how to measure each tolerance, or rework and disputes follow.

How to design internal corners, start holes, and slot geometry so wire EDM cuts them right.

When parts from different processes won't assemble despite passing inspection individually.

Four design rules determine whether carbon fiber parts handle load or fail in the mold.

Plan bridge tool geometry to survive the jump to production molds.

Minimum draft angles and uniform wall thickness prevent warping and extend mold life.

When bending sheet metal for enclosures, match the radius to material ductility.

Choose the finish based on function, not looks, or pay for rework.

Decide alloy and geometry before quoting to control cost and lead time.

Five common file errors cost quoting time and money.
