DFM checks before manufacturing

Find difficult-to-machine features early and turn them into clear questions for design and process review.

What it does

The Agent points out deep cavities, small deep holes, thin walls, small internal radii, poor tool access and questionable stock allowance.

Ask the Agent

List this part’s DFM risks by severity. For each one, give the location, the reason and a practical design or process change.

Typical answer

Analysis complete

manufacturing analysis / result

The part is reviewable, but two findings should be resolved before release.

The highest attention goes to a small deep hole and a deep pocket with tight internal corners. Neither finding automatically blocks production, but both can change the tool and process choice.

Critical

A Ø3 mm hole at 28 mm depth may need peck drilling, a longer tool or a revised hole strategy.

Warning

A 12 mm pocket with small corner radii should be checked against tool reach and the available internal radius.

Recommendation

Confirm tolerance and function before changing the design; otherwise keep the risk visible in the process plan.
