Overview
The YANRUN YR-A3020 is a fully automated hybrid coordinate measuring machine engineered for high-precision geometric metrology in quality control laboratories and production environments. It integrates contact probing capability with high-resolution optical imaging—enabling dual-mode measurement of dimensional, positional, form, and profile characteristics on both reflective and non-reflective parts. The system operates on the principle of Cartesian coordinate acquisition: motion-controlled precision stages (X/Y/Z) position the part relative to a calibrated optical axis and/or tactile probe tip, while metrological-grade image analysis algorithms compute edge coordinates, distances, angles, radii, and GD&T features (e.g., concentricity, parallelism, flatness) per ISO 1101 and ASME Y14.5 standards. Its rigid granite base, thermally stable aluminum frame, and servo-driven ball-screw motion system ensure mechanical repeatability better than 1 µm over full travel—a prerequisite for first-article inspection and PPAP validation in automotive and aerospace supply chains.
Key Features
- Fully automated operation via integrated motion control and programmable measurement routines—eliminating manual joystick dependency and operator-induced variability.
- Dual-sensor architecture: High-sensitivity SONY color CCD camera (1/2″ sensor, progressive scan) paired with optional tactile probe module for feature verification where surface texture or transparency limits optical contrast.
- Motorized 0.7–4.5× zoom lens with real-time magnification feedback ensures consistent pixel-to-unit calibration across the entire zoom range; auxiliary 2× objective extends effective magnification to 380× for micro-feature assessment (e.g., PCB solder paste deposits, watch gear teeth).
- Independent LED ring light (surface illumination) and contour backlight with continuous intensity modulation—optimized per magnification level to maximize edge contrast without saturation or glare.
- Sub-micron positional resolution (0.5 µm) on all three axes, validated per ISO 230-2; volumetric compensation applied in real time using built-in laser interferometer-derived error maps.
- Thermally isolated optical column and climate-controlled enclosure design minimize thermal drift—meeting ISO 22036 stability requirements for metrology-grade CMMs operating in standard lab conditions (20 °C ±3 °C).
Sample Compatibility & Compliance
The YR-A3020 accommodates parts up to 300 mm × 200 mm × 100 mm (L×W×H), with optional fixtures supporting irregular geometries including machined housings, stamped sheet metal, injection-molded plastics, and precision optics. Its glass stage (250 × 350 mm) enables backlit silhouette measurement of thin profiles, while the reinforced metal stage (408 × 508 mm) supports heavier components up to 25 kg. The system complies with ISO 10360-7 for optical CMM performance verification and meets the environmental operating specifications outlined in ISO 17025 Clause 6.3 for accredited calibration labs. All measurement data logs include traceable timestamps, operator ID, instrument configuration, and uncertainty budgets—supporting GLP/GMP audit readiness and FDA 21 CFR Part 11 electronic record compliance when deployed with validated software modules.
Software & Data Management
Equipped with YANRUN’s proprietary MetroVision Pro v4.x software, the YR-A3020 delivers scriptable measurement sequences, GD&T evaluation per ASME Y14.5–2018, and statistical process control (SPC) charting. Software features include automatic edge detection with sub-pixel interpolation, multi-view stitching for large-area parts, and export of measurement reports in PDF, Excel, and XML formats compliant with ISO 10303-235 (STEP AP235). Audit trails record every user action—including program edits, parameter changes, and report generation—with digital signature support. Raw image archives and coordinate point clouds are stored in vendor-neutral TIFF and ASCII XYZ formats, ensuring long-term data portability and third-party analysis compatibility (e.g., with PolyWorks or Geomagic Control).
Applications
- Dimensional verification of CNC-machined components in Tier-1 automotive manufacturing (e.g., brake caliper bores, suspension link geometry).
- Form analysis of medical device components—including orthopedic implant surfaces, catheter hub tolerances, and dental abutment thread profiles.
- PCB and semiconductor packaging inspection: solder joint coplanarity, pad alignment, fiducial mark registration, and BGA ball height distribution.
- Tooling and mold validation: cavity depth uniformity, draft angle consistency, and gate location accuracy prior to production ramp-up.
- Educational metrology training: hands-on instruction in GD&T interpretation, measurement uncertainty budgeting, and ISO/IEC 17025 documentation practices.
FAQ
Does the YR-A3020 support tactile probing in addition to vision-based measurement?
Yes—optional Renishaw-compatible analog or digital probe heads can be mounted on the Z-axis turret, enabling simultaneous or sequential contact and optical data acquisition within a single program.
What calibration standards are recommended for routine verification?
A certified step gauge (e.g., NIST-traceable 10–100 mm), ball bar (for volumetric performance), and optical resolution target (e.g., USAF 1951) are required for daily, weekly, and quarterly checks per ISO 10360-7 Annex D.
Can measurement programs be exported and reused across multiple YR-A3020 units?
Yes—MetroVision Pro uses platform-independent XML-based program files that retain all geometric tolerances, lighting presets, and motion paths, enabling cross-site deployment without revalidation.
Is environmental temperature monitoring integrated into the system?
The YR-A3020 includes an internal ambient temperature sensor feeding real-time compensation coefficients to the motion controller; external hygrothermograph integration is supported via RS-232 or Ethernet for full ISO 17025 environmental logging.
How is measurement uncertainty quantified and reported?
Uncertainty is calculated per GUM (JCGM 100:2008) using Type A (repeatability) and Type B (calibration certificate, thermal expansion, resolution) components; expanded uncertainty (k=2) is embedded in every exported report header.
