Top Defects you see in Laser Cut Parts

[Finglas]

Hi,

I'm doing a Six Sigma defect reduction project with a company I just started working in as part of a distance learning course I'm doing (so the project isn't being driven by the company but more so by my needs unfortunately). I'm not being given access to customer complaints and I don't feel I am in a position to contact customers to ask them directly what types of defects they are most commonly coming across when they receive our products.

I am looking for issues that people mainly come across when receiving laser cut parts. Some examples I have seen which are directly related to the laser cutting process include excess dross, sharp edges, poor quality holes, rough surfaces along the edges, parts warped due to excessive hear. Other defects include incorrect quantities, scratches on parts, missing holes.

Would appreciate if anyone could give me other examples of errors.

Thanks.

No parts with Dross, sharp edges, poor quality holes, rough surfaces, or warped parts should ever end up in a customers hands, good quality control dept. or employee should be enough to prevent that from ever happening, and a laser that is kept up and in good shape shouldn't produce bad quality cuts, although this has a lotto do with operator. scratches can be problematic but can also be overcome with prep work pre and post, incorrect counts can be solved by weighing and missing holes someone needs to holler at the engineers lol

Yes I agree with your view. I think it's the system that's in place that needs to be improved. Thanks for your feedback.

First of each part should be inspected by the laser operator for size and hole location. Dross on the bottom side should be cleaned off parts before shipping. And if top edge is sharp customer should specify whether they want sharp edges broken or not. A sharp 90° edge is what a laser is supposed to produce.
