Scratch Detection Systems FAQs
Straight answers to common questions about scratch detection systems, including suitable applications, limitations and what to send us.
The starting question is whether the required scratch can be made visible, repeatably, against normal surface variation. There is no application-independent minimum scratch size established by this site: the decision, samples, inspected area and presentation must be assessed together.
An optical trial should record the demonstrated scratch range and coverage, missed defects and false rejects, and the production response to missing or uncertain results. Retain any exclusions in the agreed scope.

Plan scratch detection systems around representative good, bad and marginal samples, line presentation, lighting, reject handling and challenge criteria. Discuss an optical feasibility trial with Oxford Vision Systems. The answers below explain suitable applications for Scratch Detection Systems, what information helps and what still needs an application-specific check.

Practical answers about scratch detection systems
How do we assess whether a vision system can detect our minimum scratch size?
Supply real surfaces with acceptable marks and scratches at the rejection boundary. Include their direction and location, normal finishes and the proposed part position or movement. Compare lighting and views on that same set and record weak or unseen areas; camera pixel count alone does not establish dependable detection. See the scratch decision and coverage guide.
How should a project for scratch detection systems begin?
Agree the surface region and cosmetic acceptance rule, then index good, bad and borderline examples with expected decisions. Identify any functional requirement needing a separate test. Describe normal finish variation and how the part will be presented before choosing an optical arrangement.
Can you quote scratch detection systems from a short description?
An early budget range may be possible, but a reliable scope needs the reference samples, required surface coverage, finish range, part presentation and line interfaces. Identify any unresolved optical trial, recipe selection or rejected-part handling work so the quotation can state what is included and still needs confirmation.
What information should we send about scratch detection systems?
Send authorised part drawings or photographs, marked scratch locations and agreed good, bad and borderline samples. Include normal finish and batch variation, proposed rotation or tilt, movement at capture, fixture restrictions and existing trial images. Explain how parts and inspection results are tracked and how uncertain results are handled.
How will performance be checked?
Compare repeated results with the agreed sample decisions across the demonstrated finish, direction, location and presentation range. Record missed unacceptable scratches and rejected acceptable surfaces separately. Check the agreed recipe, part tracking, rejected-part and missing-image responses, and retain the settings, exclusions and unresolved cases.
What are the main limitations?
A camera can only assess a property made visible and repeatable by the inspection setup. Sample diversity and marginal cases determine how meaningful a feasibility result is. Visual inspection does not replace hidden, destructive, functional or statutory tests.
What alternatives should be considered for in-line inspection using automated surface-scratch detection?
A simple presence or position check may suit a purpose-built sensor if that is the actual requirement; it does not establish that a scratch is acceptable. Consider offline surface review or metrology where the required decision is not demonstrated inline, and separate functional or destructive tests where needed. Compare each route against the same acceptance rule and its stated limits.
Can the proposed solution guarantee regulatory compliance?
No solution can guarantee compliance on its own. Applicable law, current standards, risk assessment, validation and conformity responsibilities must be addressed for your complete application.
