Quality Assurance & Inspection for Precision CNC Machining

Avanti Engineering ensures CNC machining quality through ISO 9001:2015–aligned processes, C=0 acceptance sampling, SPC-driven in-process checks, NIST-traceable metrology, first-article/ISIR verification, optional PPAP evidence, and documented final inspection—with optional 100% high-speed vision sorting to drive near-zero PPM.

Our Quality Approach

Quality isn’t a checkpoint—it’s built into every operation from raw material selection to shipping. We use defined best practices and continuous improvement to reduce variation, eliminate defects, and shorten lead times.

• C=0 acceptance sampling (zero defects accepted in the sample)

• Low PPM performance maintained through rigorous in-process control

• Optional 100% vision sorting to reach the tightest AQL/PPM targets

Metrology & Measurement Capabilities

Our quality lab uses NIST-traceable equipment for both contact and non-contact measurements to verify tight tolerances and surface finishes.

• Attribute gauges & thread gauges

• Micrometers and microprocessor measurement systems

• OASIS non-contact inspection system

• Optical comparators

• Flatness and roundness measurement systems

• Profilometer (surface roughness)

• Hardness testers

First Article, Reporting & Traceability

Every new part begins with preliminary sampling and a first-article/ISIR to lock in capability and documentation.

• ISIR with full dimensional results (typical 5-piece full layout)

• Lot-level traceability for material, processes, and inspection records

• Clear quality reports to expedite approvals and launches

PPAP Support (When You Need Automotive-Level Evidence)

Upon request, we provide PPAP packages tailored to your requirements.

• Control Plans and Process Flow Diagrams

• PFMEA (design/process as required)

• MSA (gage R&R as applicable)

• Dimensional layouts and inspection records

• Material and special-process certifications; IMDS submissions

• PSW (Part Submission Warrant)

Final Inspection & Shipping

Before anything leaves our dock, parts pass a documented final inspection against your print and PO. For approved supplier programs, we ship direct to your facility or distribution network with the evidence you need on file.

• Optional 100% high-speed vision sorting to further reduce PPM

• Packaging to spec to protect finishes and critical dimensions

Quick Glossary (≤40-word definitions)

• C=0 Sampling: Zero-acceptance sampling—any defect in the sample rejects the lot.

• PPM: Parts per million; a defect-rate metric over time.

• AQL: Acceptable Quality Limit; maximum defect rate allowed in sampling.

• ISIR: Initial Sample Inspection Report; dimensional proof the part meets print.

• PPAP: Production Part Approval Process; complete evidence package (e.g., Control Plan, PFMEA, MSA, PSW PFD).

• SPC: Statistical Process Control; uses data to control process variation.

• MSA: Measurement Systems Analysis; confirms gage accuracy and repeatability.
