For a machined carbon fiber part, make the inside surface and both edges part of the inspection discussion when those regions matter to the assembly.<\/p>\n<h2>Follow the feature through the thickness<\/h2>\n<p>An entrance photograph records one face. The other face may have different edge quality, and a short bore can conceal loose material or a local defect from that view. Look at the feature from both accessible sides before fitting hardware. If only one side remains accessible in the finished assembly, carry out the relevant checks at an earlier stage.<\/p>\n<h2>Decide what can actually be seen<\/h2>\n<p>Lighting, magnification and the angle of view affect what an inspection image shows. A dark bore photographed from directly above can look clean simply because the surface is not visible. Use a method suited to the feature and retain enough context to identify the hole. Avoid interpreting an unclear photograph as evidence that an edge condition meets the requirement.<\/p>\n<h2>Tie the requirement to the hole function<\/h2>\n<p>A passage for a cable has a different concern from a locating hole or an attachment hole. State whether the review is looking for obstruction, a contact edge, dimensional fit or a specified defect condition. Deburring and finishing can change dimensions, so a general instruction to remove all roughness should not override a controlled fit or an approved process.<\/p>\n<figure><a href=\"https:\/\/www.carbon-fiber-corp.com\/wp-content\/uploads\/2026\/10\/ly-geo-20261014-11-bore-edges-2.webp\" aria-label=\"Open the full-size diagram\"><img src=\"https:\/\/www.carbon-fiber-corp.com\/wp-content\/uploads\/2026\/10\/ly-geo-20261014-11-bore-edges-2.webp\" alt=\"Report which regions the inspection method actually covers.\" width=\"1600\" height=\"1000\" loading=\"lazy\" decoding=\"async\"><\/a><figcaption>Report which regions the inspection method actually covers. <a href=\"https:\/\/www.carbon-fiber-corp.com\/wp-content\/uploads\/2026\/10\/ly-geo-20261014-11-bore-edges-2.webp\">View full size<\/a>.<\/figcaption><\/figure>\n<h2>Make incomplete coverage visible in the report<\/h2>\n<p>Identify features that could not be inspected and explain why.
