# How can a metal stamping shop use computer vision to check parts as they come off the press?

Place a camera and steady lighting at the press exit or end of line, then use a model trained on the shop own part images to mark likely splits, cracks, wrinkles, burrs, dents, scratches, missing or misplaced holes and slug marks. Each mark is tied to the press, die and time, so the die setter can spot a die problem early and a trained inspector can decide whether to pass, sort or scrap the parts. The model only flags what the camera can see; it does not replace dimensional checks, first piece approval or quality sign-off, and people make every disposition call.

## What this means in practice

- Set up a fixed camera and steady lighting at the press exit or end of line
- Collect images of parts that inspectors have already passed or rejected, for each part number and die
- Label the defect types the quality team tracks, plus good examples of each part
- Alert the die setter and inspector to flagged parts and log flags by press, die and time
- Add reviewed images back into training whenever a new part, die or material comes in

## How Lid Vizion approaches it

We start with the business decision and operating context, define ownership and measurable milestones, then use configuration, integrations, automation, or custom software only where each earns its place.
