Overview
The FARO Arm Coordinate Measuring Machine (CMM) – Distance Accuracy & Repeatability Verification System is a metrology-grade solution engineered for third-party validation and periodic performance verification of portable articulated arm CMMs in accordance with ISO 10360-2:2023 (“Geometrical product specifications (GPS) — Acceptance and reverification tests for coordinate measuring machines (CMMs) — Part 2: CMMs used for measuring linear dimensions”). This system does not function as a standalone measurement instrument but serves as a traceable reference platform for quantifying two critical static performance indicators: distance measurement accuracy (maximum permissible error over defined length intervals) and distance measurement repeatability (standard deviation of repeated measurements under identical conditions). It leverages certified gauge blocks, laser interferometer-traceable artifacts, and thermally stabilized environmental protocols to establish metrological confidence in FARO QuantumS, Edge, or Platinum series arms deployed in quality labs, aerospace manufacturing cells, and automotive Tier-1 supplier inspection stations.
Key Features
- ISO 10360-2 compliant test methodology for distance accuracy (EL) and distance repeatability (RL) assessment across multiple length ranges (e.g., 100 mm to 2,500 mm)
- Integrated thermal monitoring suite (±0.1 °C resolution) synchronized with measurement acquisition to correct for material expansion per ISO 10360-2 Annex B
- Multi-axis artifact positioning rig enabling evaluation of distance errors in X-, Y-, and Z-directional vectors, as well as diagonal space distances
- Automated data capture sequence aligned with ISO 10360-2 Clause 6.3 requirements: minimum 10 repeated measurements per length interval, randomized probe approach direction
- Traceable calibration certificate issued by CNAS-accredited laboratory (ISO/IEC 17025), including uncertainty budgets for all reference standards used
- Support for both single-point probing and continuous scanning modes during verification—ensuring relevance to actual operational workflows
Sample Compatibility & Compliance
This verification system is compatible with all FARO portable arm models equipped with integrated touch-trigger probes or scanning heads (e.g., FARO Platinum 7-Axis, QuantumS 7-Axis, Edge 6-Axis). It supports probe tip diameters from 1 mm to 6 mm and accommodates stylus configurations up to 500 mm in length. All test procedures adhere strictly to ISO 10360-2:2023, ASTM E2924-22 (Standard Guide for Verification of Coordinate Measuring Systems), and VDI/VDE 2617 Part 9 (Accuracy of Coordinate Measuring Machines). The system satisfies prerequisite conditions for GLP-compliant metrology audits and supports documentation required for IATF 16949 clause 7.1.5.2 and AS9100D clause 7.1.5.1.
Software & Data Management
Verification execution and reporting are managed through FARO CAM2 Measure 10.8 or later, configured with the ISO 10360-2 Validation Module. Raw measurement data—including timestamps, temperature logs, probe qualification status, and environmental pressure—is stored in encrypted SQLite databases compliant with FDA 21 CFR Part 11 requirements (electronic signatures, audit trails, role-based access control). Export formats include PDF reports with embedded uncertainty statements, CSV for SPC integration, and XML for ERP/MES system ingestion. All reports contain mandatory fields per ISO 10360-2 Table 1: test date, operator ID, arm serial number, probe ID, environmental conditions, measured values, calculated EL/RL, and pass/fail determination against declared MPE.
Applications
- Annual or biannual acceptance/reverification of FARO arms prior to use in PPAP submissions
- Root-cause analysis following out-of-tolerance measurements in first-article inspections
- Pre- and post-repair validation after joint replacement, encoder recalibration, or mechanical realignment
- Supporting internal metrology audits under ISO/IEC 17025 Clause 6.4.10 (equipment verification)
- Generating objective evidence for customer-facing quality agreements requiring documented CMM performance stability
- Training metrologists on ISO 10360-2 conformance testing methodology and uncertainty propagation fundamentals
FAQ
What is the difference between distance accuracy (EL) and distance repeatability (RL) per ISO 10360-2?
EL quantifies the maximum deviation between the measured distance and the certified length of a reference artifact; RL expresses the standard deviation of ≥10 repeated measurements under identical setup conditions.
Can this system verify FARO arms calibrated to ISO 10360-8 (scanning performance)?
No—this package is specific to ISO 10360-2 linear distance metrics. Scanning performance requires separate validation per ISO 10360-8 using sphere stacks and plane artifacts.
Is environmental conditioning required during verification?
Yes—tests must be conducted in a temperature-stabilized environment (20 °C ±1 °C, gradient ≤0.5 °C/h), with humidity maintained at 40–60% RH per ISO 10360-2 Clause 5.2.
Does the rental include on-site technician support?
Rental packages may optionally include certified FARO Metrology Engineer deployment for setup, execution, and report sign-off—subject to regional availability and advance scheduling.
How frequently should distance accuracy verification be performed?
Per ISO 10360-2 Clause 4.2, verification is required upon initial installation, after major maintenance, and at intervals defined by risk assessment—typically every 6 to 12 months for production-critical applications.
