PW Optical Measurement System OMV2018 – Ultra-Large Travel CNC Video Measuring Machine

Overview

The PW OMV2018 is an ultra-large travel, CNC-controlled video measuring machine engineered for high-precision dimensional metrology in industrial quality control and R&D environments. Utilizing non-contact optical measurement principles—primarily based on high-magnification telecentric imaging, sub-pixel edge detection, and coordinate metrology—the system captures geometric features of static workpieces placed on a fixed granite table. Its moving-bridge architecture eliminates part movement during measurement, minimizing thermal drift and mechanical loading errors. Designed for repeatable, traceable, and auditable measurements, the OMV2018 conforms to core dimensional metrology best practices aligned with ISO 10360 (coordinate measuring machines), ISO 1101 (geometrical tolerancing), and VDI/VDE 2617 (accuracy testing of CMMs). The system supports both manual operator-assisted inspection and fully automated batch measurement routines.

Key Features

• Monolithic granite base and bridge structure ensuring long-term mechanical stability and thermal inertia
• Four-axis CNC closed-loop motion control (X/Y/Z + zoom) with AC servo motors, precision ground ball screws, and linear guideways
• High-resolution open-type optical encoder scales with 0.1 µm resolution across all axes
• 6.5× motorized zoom lens with automatic magnification calibration—single-point pixel calibration valid across entire zoom range
• 10-megapixel progressive-scan digital camera optimized for low-noise, high-contrast image capture under controlled illumination
• Programmable 5-ring, 8-sector LED surface illumination system offering 256-step brightness control per zone for optimal feature contrast on diverse materials (metal, plastic, PCB, ceramic)
• Native PW proprietary metrology software with full GD&T evaluation (form, profile, orientation, location, runout), statistical process control (SPC) reporting, and customizable report templates
• Modular sensor expansion interface supporting tactile probe heads (optional), laser displacement sensors, and chromatic confocal modules for hybrid contact/non-contact measurement

Sample Compatibility & Compliance

The OMV2018 accommodates parts up to 2000 mm × 1800 mm × 200 mm (L×W×H), making it suitable for large-format components such as automotive body panels, aerospace structural brackets, sheet metal assemblies, and precision molds. Its fixed-part design eliminates repositioning artifacts common in moving-table systems. All measurement data—including image snapshots, coordinate point clouds, GD&T results, and operator annotations—are timestamped and stored with full audit trail capability. Software supports export to industry-standard formats (DXF, STEP, CSV, XML) and integrates with MES/QMS platforms via OPC UA or TCP/IP protocols. While not certified to FDA 21 CFR Part 11 out-of-the-box, the system architecture allows configuration for GLP/GMP-compliant environments when deployed with validated software builds, electronic signature modules, and change-controlled documentation workflows.

Software & Data Management

The included PW VisionMetro Pro software provides a unified environment for programming, execution, analysis, and reporting. It features intuitive CAD-based alignment (import DXF/IGES), auto-edge detection with adjustable threshold and noise filtering, multi-point pattern recognition for repetitive features, and real-time measurement feedback during program execution. All measurement sequences are scriptable using built-in macro language or Python API (SDK available upon request). Data integrity is enforced through role-based access control, versioned measurement programs, and encrypted local database storage. Raw images and calibrated coordinate data are retained for retrospective analysis, root cause investigation, and metrology uncertainty budgeting per ISO/IEC 17025 guidelines.

Applications

• Dimensional verification of large-scale machined and stamped components in automotive Tier-1 suppliers
• GD&T validation of weldments and fabricated assemblies in heavy equipment manufacturing
• First-article inspection and FAI report generation compliant with AS9102 and PPAP requirements
• Tooling and mold verification including cavity depth, draft angle, and surface flatness assessment
• PCB and panel-level inspection for solder mask registration, fiducial placement, and board outline conformity
• Reverse engineering support via dense point cloud acquisition and surface fitting (with optional laser scanning module)

FAQ

What is the maximum measurable part size supported by the OMV2018?

The standard measurement volume is 2000 mm × 1800 mm × 200 mm (X × Y × Z); custom extended Z-axis configurations are available upon request.
Does the system comply with ISO 10360 accuracy standards?

Yes—the OMV2018 undergoes factory calibration per ISO 10360-2 and includes a traceable calibration certificate; periodic recalibration is recommended annually or per usage intensity.
