CNC Inspection Services and CMM Quality Control
JADE-CNC provides drawing-based CNC inspection services for precision metal and plastic parts, including in-process checks, CMM measurement, first article inspection, final dimensional verification, surface and thread checks, and inspection documentation when required.
Inspection Built Into Every Production Stage
Inspection requirements are reviewed before machining and checked throughout production as part of JADE-CNC's quality assurance process. This helps support tolerance verification, manufacturing inspection, and documentation control so delivered parts can be checked against approved drawings, critical dimensions, surface requirements, and customer reporting needs.
Drawing-Based Inspection
Critical dimensions, tolerances, threads, finishes, and documentation requirements are identified from your 2D drawing.
In-Process Quality Checks
Operators and quality staff verify key features during machining so deviations can be corrected before final production.
Final Dimensional Verification
Completed parts are checked against the approved drawing using suitable manual, optical, and coordinate measurement methods.
Reports and Traceability
Dimensional reports, CMM data, first article reports, and material certificates can be supplied when specified at quotation.
Inspection Methods for CNC Machined Parts
Inspection planning depends on part geometry, tolerance, material, surface finish, production quantity, and customer documentation requirements. JADE-CNC can review drawings and identify suitable inspection methods before production.
| Inspection Method | Used For | Typical Output | RFQ Notes |
|---|---|---|---|
| CMM Inspection | 3D dimensions, GD&T, position, profile, flatness | Dimensional report or FAI report when required | Provide critical dimensions, datum structure, and GD&T callouts. |
| Visual Inspection | Cosmetic condition, surface defects, finish consistency | Visual check record or cosmetic approval | Provide cosmetic grade, sample photo, or acceptance boundary if important. |
| Caliper / Micrometer Inspection | Basic dimensions, thickness, diameters, simple features | Dimensional record | Suitable for many standard machined features. |
| Height Gauge Inspection | Heights, steps, and planar feature relationships | Inspection record | Useful for machined plates, blocks, and stepped features. |
| Surface Roughness Testing | Ra / surface texture requirements | Roughness report | Specify required Ra only where function or appearance requires it. |
| Thread Gauge / Plug Gauge | Threads, holes, and functional fit | Go / No-Go record | Provide thread specification, class, depth, and fit requirement. |
| Coating Thickness Check | Anodizing, plating, paint, powder coating | Coating thickness record | Confirm if dimensions should be measured before or after finishing. |
| First Article Inspection | Initial production verification | FAI report | Useful for new parts, critical features, or production transition. |
Define Inspection Requirements Before Production
If your project requires dimensional reports, FAI, CMM inspection, coating thickness checks, or special documentation, include those requirements with your RFQ.
CNC Inspection options at JADE-CNC
JADE-CNC uses a practical quality control system to review part geometry, machining tolerance, material condition, surface finish, production quantity, and customer reporting requirements. For precision measurement, our team selects suitable tools such as CMM, optical measurement equipment, calipers, micrometers, height gauges, thread gauges, and other calibrated inspection methods according to the drawing.
CMM Measurement
Coordinate measurement for complex geometries, positional relationships, profiles, and tightly controlled critical features.
Optical Inspection
Non-contact measurement for small features, contours, edges, and parts that are difficult to probe mechanically.
Manual Metrology
Calipers, micrometers, bore gauges, height gauges, pin gauges, and other calibrated tools for routine dimensional checks.
Surface and Thread Checks
Surface roughness, coating appearance, thread size, and go/no-go requirements are verified when specified.
First Article Inspection
Initial parts are inspected before batch production to confirm process capability and drawing compliance.

Define Your Inspection Requirements Before Production
Upload your 2D drawing and 3D model with critical dimensions, tolerances, material grade, surface finish, sample size, and reporting requirements. JADE-CNC will review the inspection scope together with the machining process and confirm whether CMM inspection, first article inspection, dimensional reporting, material certificates, or finish checks should be included in the quotation.
CNC Inspection Services FAQ
Please provide a 2D drawing with datums, tolerances, critical dimensions, thread and surface requirements, plus the 3D model where available. State any required sample size, report format, material certificate, or customer-specific inspection standard during RFQ.
Yes. CMM inspection can be used for complex geometries, positional relationships, profiles, datums, and tightly controlled features. Suitability depends on part size, geometry, accessibility, and tolerance.
Yes. First article inspection can be completed before batch production, with a marked drawing, dimensional results, and supporting records supplied according to the agreed quotation requirements.
A full dimensional inspection report can be provided when requested before production. The report scope, sample quantity, measurement method, and any special fixtures should be confirmed during quotation.
Depending on the feature, we use CMM, optical measurement equipment, calipers, micrometers, height gauges, bore gauges, pin gauges, thread gauges, surface roughness testers, and other calibrated tools.
Inspection is performed at planned stages. Critical features can be checked during setup and machining, followed by final dimensional, visual, and documentation checks before shipment.
Material certificates and traceability records can be supplied when requested at quotation. Requirements should be stated before material purchasing so they can be included in sourcing and documentation control.
The affected part or batch is held for review. We verify the measurement method, identify the cause, evaluate correction or remake options, and communicate any issue that could affect the approved drawing requirements.
Yes. We can check specified surface roughness, coating appearance, thread size, thread gauges, and other finish requirements using appropriate inspection methods.
Upload the drawing and note the critical dimensions, desired report type, sampling level, material documentation, and any industry or customer standard. We will confirm feasibility and inspection cost before production.
