What needs to be checked?

Measurements
➡️ Tight tolerances

Any dimension with a tolerance tighter than ISO 2768 medium

Any tolerances specified directly on the drawing should be included in the QC report

➡️ Bores and threads
Check every thread in the part
For small threads and holes (up to 8mm), use gauges where possible
Pay particular attention to the depth of blind holes and length of threads (both through and blind)

If there are no tight dimensions (e.g. tolerance grade 5/6/7), pick the 3-7 most critical (in your opinion) dimensions, add bubbles and fill in the table with records accordingly.

Surface

➡️ Roughness
➡️ Hardness
➡️ Marking (engraving)
➡️ Coating/other special finishing

If specified - always check!
Please check the information on markings: in production remarks AND on drawings

Special remarks

➡️ Every remark should be checked and confirmed
➡️ Just write OK/NOK for every remark
➡️ Keep the edges sharp
➡️ Visible surface (i.e. no scratches)
➡️ What else is required (see remarks and customer request)
➡️ Certificates

What if I don't know what the remark means (like "PKSN23")? Contact us! PRODUCTION@XOMETRY.DE
