Aerospace and medical components in France<\/b> share two demands that most other industries do not combine: extreme dimensional precision and complete traceability. A single out-of-tolerance seal or catheter tip can fail an audit. So selecting the right <\/span>vision measuring system<\/b><\/a> can satisfy both the engineering drawing and the auditor at once. Choosing a non-contact platform that removes the need for inspection.<\/span><\/p>\n

Why Contact Measurement Fails on Delicate and Thin-Walled Parts<\/b><\/h2>\n

Contact probing works by pressing a stylus against a surface. On rigid, prismatic parts that are reliable. On the thin-walled, flexible, or fragile geometry common to aerospace and medical work, the same probe force becomes the source of error. A thin extruded profile deflects. A silicone seal compresses. A polymer catheter wall distorts before the point is even recorded.<\/span><\/p>\n

The result is a measurement that reflects the probe, not the part. For non-contact measurement of thin-walled parts, this is disqualifying. When tolerances run to microns and the material yields under the lightest touch, the measuring method itself must apply no load at all.<\/span><\/p>\n

Non-Contact Vision Measurement Explained: Telecentric Lenses, 5MP Imaging, Zoom Magnification<\/b><\/h2>\n

A <\/span>video measuring machine<\/b> captures geometry with light. A telecentric lens holds magnification constant regardless of part height, so edges remain sharp and dimensions stay true across the depth of field. A 5-megapixel sensor resolves fine detail, and zoom magnification lets one system move from a full profile view to a single micro-feature without changing hardware in France<\/b>.<\/span><\/p>\n

Sipcon’s HERO video measuring system applies this principle to demanding parts, while the Cross Hair Based VMS offers a focused, operator-guided route for simpler routines. For low-magnification review and quick shop-floor checks, a Table Top Magnifier complements the range. Each captures dimensions without touching the workpiece.<\/span><\/p>\n\n\n\n\n\n\n\n

The Traceability Problem: What EN 9100 and ISO 13485 Auditors Ask For<\/b><\/h2>\n

Precision alone does not pass an audit. EN 9100 for aerospace quality management and ISO 13485 for medical devices both require that every measurement be traceable to a national standard, produced under a controlled process, and documented so a third party can reconstruct it. ISO 9001 sets the underlying quality-management expectations.<\/span><\/p>\n
