Hexagon TubeInspect High-Precision High-Speed Optical Tubing Inspection System

Overview

The Hexagon TubeInspect High-Precision High-Speed Optical Tubing Inspection System is an industrial-grade, handheld optical coordinate measurement system engineered for rapid, non-contact geometric verification of tubular components—including bent tubes, stamped fittings, forged elbows, and freeform piping assemblies. It operates on a multi-camera photogrammetric principle: synchronized GigE Vision cameras capture high-fidelity 2D images from multiple perspectives; these are triangulated in real time against a calibrated 3D glass reference target to reconstruct precise 3D point clouds. Unlike traditional tactile CMMs or laser trackers, TubeInspect eliminates mechanical probing constraints and thermal drift sensitivity—enabling stable metrology directly on the shop floor, even under ambient temperature fluctuations and vibration-prone environments. Its turnkey single-station architecture integrates hardware, calibration, and software into one cohesive platform, delivering sub-0.05 mm volumetric accuracy (per VDI/VDE 2634 Part 2) without requiring climate-controlled metrology labs.

Key Features

• Fully enclosed, IP54-rated mechanical housing designed for long-term operation in harsh production environments—including oil mist, metal dust, and intermittent coolant exposure.
• Sub-3-second measurement cycle per tube part, scalable across batch sizes from prototype validation to high-volume inline quality control.
• Thermally stable carbon-fiber composite frame and rigidized glass reference target ensure <0.002 mm repeatability over 8-hour shifts (verified per ISO 10360-2).
• Dual configuration options: P8.2 (compact footprint for small-diameter tubing ≤Φ25 mm) and P16.2 (extended field-of-view for large-diameter pipes up to Φ60 mm).
• Two optical sensor variants: Standard version with 3 MP global-shutter industrial cameras; HRC version featuring 12 MP resolution for micro-feature capture—e.g., weld seam geometry, bracket mounting hole orientation, and flange face flatness.
• On-device hotkey buttons enable full measurement initiation, pass/fail confirmation, and report generation without returning to a host PC—reducing operator motion waste and supporting lean manufacturing workflows.
• GigE Vision interface ensures deterministic image synchronization (<100 µs jitter) and low-latency data transfer to BendingStudio XT, enabling real-time deviation mapping against nominal CAD models.
• Integrated LED illumination system provides uniform, shadow-free illumination across the entire measurement volume; intensity and profile are programmatically adjustable via software API.

Sample Compatibility & Compliance

TubeInspect supports dimensional inspection of metallic and composite tubular components with diameters ranging from 3 mm to 60 mm, wall thicknesses from 0.5 mm to 5 mm, and bend radii as tight as 1.5×D (where D = tube diameter). It accommodates elastic deformations during handling, accommodates forged geometries with surface scale or mill finish, and tolerates minor surface oxidation without compromising feature detection. The system complies with core metrological standards applicable to optical CMMs: ISO 10360-2 (repeatability and reproducibility), VDI/VDE 2634 Part 2 (optical 3D measuring systems), and ASTM E2925 (performance evaluation of photogrammetric systems). BendingStudio XT includes configurable audit trails, electronic signatures, and user-access controls aligned with FDA 21 CFR Part 11 and EU Annex 11 requirements for regulated manufacturing environments.

Software & Data Management

BendingStudio XT serves as the central metrology hub for tube fabrication workflows. It unifies CAD model import (native support for STEP, IGES, Parasolid, and CATIA V5 formats), GD&T definition (ASME Y14.5 / ISO 1101), automated reporting (PDF/Excel/XML), and SPC integration (X-bar R charts, capability indices Cp/Cpk). The CAD Adapter module enables virtual alignment of nominal geometry—eliminating physical fixtures when measuring complex end fittings, brackets, or flanges. All measurement data is timestamped, version-controlled, and exportable via RESTful API to MES (e.g., Siemens Opcenter, Rockwell FactoryTalk) or PLM platforms (e.g., Teamcenter, Windchill). Raw image archives, point clouds, and deviation heatmaps are stored in vendor-agnostic HDF5 format for long-term traceability and third-party analysis.

Applications

• Real-time first-article inspection of bent tube assemblies prior to welding or assembly.
• In-process verification of CNC tube benders—detecting springback, ovality, or angular deviation before downstream operations.
• Reverse engineering of legacy or undocumented tube components for digital twin creation.
• Supplier quality assurance audits—validating conformance to OEM tube drawings with full GD&T reporting.
• Tooling validation and wear monitoring of bending dies and mandrels through periodic geometric comparison.
• Automated cell integration: HRC-equipped units synchronize with ABB/KUKA robot controllers via Ethernet/IP or Profinet for lights-out inspection cycles.

FAQ

Is TubeInspect certified for use in regulated industries such as aerospace or medical device manufacturing?
Yes. BendingStudio XT supports 21 CFR Part 11-compliant electronic records and signatures, including role-based access control, audit trail logging, and secure data archiving—validated for GxP environments.
Can TubeInspect measure tubes with reflective or black-anodized surfaces?
It employs adaptive lighting and multi-angle imaging to mitigate specular reflection; matte spray application is recommended for highly polished stainless steel, but not required for standard mill-finish or anodized alloys.
What CAD file formats does BendingStudio XT accept for nominal comparison?
STEP AP214/AP242, IGES, Parasolid (.x_t/.x_b), CATIA V5 (.CATPart/.CATProduct), and native SolidWorks (.sldprt/.sldasm) files are fully supported.
Does the system require annual recalibration by Hexagon service engineers?
No. The integrated 3D glass reference target enables user-performed self-calibration in under 5 minutes using built-in routines compliant with ISO 10360-2 Annex D.
How is measurement data secured and backed up?
All datasets are encrypted at rest (AES-256) and transmitted over TLS 1.2; backup policies can be configured to local NAS, cloud object storage (AWS S3, Azure Blob), or enterprise backup suites (Veeam, Commvault).
