Record objective evidence for each item. Failed critical items require a corrective action before certification audits. ## Content **Intro:** This machine shop inspection checklist doubles as an internal audit checklist for shops working toward ISO 9001 or AS9100. It follows the job flow from contract review to shipment and ends with management system records. A quality manual outline is included below. **Sections:** #### How to use it for inspections and audits **Body:** For a shop inspection, walk a live job from traveler to packed box and tick each item with evidence such as a cert number or gauge ID. For an internal audit, sample several jobs and check the management system group, then write findings with the requirement, evidence and corrective action owner. Audit each process at least annually, more often where risk or past findings are higher. #### Quality manual outline for a machine shop **Body:** ISO 9001 no longer requires a quality manual, but customers and AS9100 certification bodies still like a short one. A practical outline keeps it to a few pages and points to procedures. **Bullets:** - Scope, products and exclusions - Quality policy and measurable objectives - Organization, roles and authorities - Process map: quote, order review, planning, machining, inspection, shipping - Controls for documents, records, calibration and nonconformance - Supplier control and special process approval - Internal audit, corrective action and management review #### Evidence auditors look for **Body:** Auditors want traceability: a part in the box should lead back to material cert, program revision, operator, inspection record and gauge calibration. They also check that the drawing revision on the floor matches the order and that nonconforming product cannot ship by accident. Keep the evidence in the ERP job record so it is retrievable in minutes, not hours. #### Common findings and fixes **Body:** Frequent findings in machine shops include expired gauge calibration, missing flow-down review, outdated drawing revisions at the machine, undocumented first piece results and corrective actions without effectiveness checks. Close them by tying calibration due dates to the ERP, controlling the traveler revision and requiring sign-off fields in the inspection step. A private AI over your quality records can answer audit questions such as which jobs used a gauge that later failed calibration. **Cta:** Netray can add a private on-prem AI layer to your ERP and quality records so audit questions about gauges, certs and revisions are answered from your own data. **Faq:** #### How often should a machine shop do internal audits? **Answer:** At least once a year per process for ISO 9001 or AS9100, with higher frequency for high-risk processes, new processes or areas with past findings. Plan the schedule in advance and keep audit reports as records. #### Do I need a quality manual for ISO 9001? **Answer:** No, ISO 9001:2015 does not require one, but a short manual is still useful for customers and for AS9100 shops. Keep it brief and reference your procedures instead of repeating them. #### What should a machine shop inspection checklist cover? **Answer:** Order review, material certs, special process approval, first piece, in-process checks, final inspection, gauge calibration, nonconformance control, packaging and traceability. Management system records are added for an internal audit. #### What is the difference between inspection and audit here? **Answer:** Inspection checks product and a job against requirements. An audit checks that the management system is followed and effective, using sampled jobs as evidence.
