How are sheet metal parts inspected?

My idea is that it is still necessary to scratch the important level according to the requirements of the production process and the finished product:

1. affecting the final appearance, clearance, as the key dimensions (the company's products on the appearance of one of the biggest problems is that the gap between the sheet metal is not the same, large and small slits jagged, it looks like a cottage)

2. sheet metal assembled to match the size of the inter-assembled, most of them are the studs and fixed holes between the The fit of the template, the usual inspection to the template with the test, in case of emergency to the actual production of the actual matching test;

3. the correctness of the machining surface to the drawing comparison or sample comparison, (the level of the supplier is also sub-par, each batch of 1-2 machining surface anti-off)

4. other dimensions, sampling

This avoids wasting valuable man-hours on unnecessary dimensions< /p>

We are not able to provide you with a complete list of the most important dimensions. /p>
