PW Optical Metrology Systems PW-AM800 Four-Axis Fully Automatic Vision Measuring System

Overview

The PW Optical Metrology Systems PW-AM800 is a four-axis fully automatic vision measuring system engineered for high-precision 2D geometric metrology in quality control laboratories, precision machining workshops, and R&D facilities. Utilizing high-resolution digital imaging, motorized XYZ-stage translation, and a programmable coaxial telecentric illumination system, the PW-AM800 performs non-contact dimensional inspection based on pixel-level edge detection algorithms calibrated against NIST-traceable reference standards. Its four-axis architecture integrates X-Y linear motion, Z-axis focus control, and a rotating θ-axis stage—enabling comprehensive profile acquisition without manual repositioning. Designed for ISO/IEC 17025-compliant environments, the system supports traceable measurement uncertainty estimation per ISO 15530-3 and conforms to GD&T principles defined in ASME Y14.5 and ISO 1101. It operates under controlled ambient conditions (20 ± 1 °C, 40–60% RH) to ensure thermal stability and repeatability across extended measurement cycles.

Key Features

• Four-axis synchronized motion control (X, Y, Z, θ) with closed-loop stepper motors and optical encoders for sub-micron positioning resolution
• Automated contour scanning and reverse-profile tracing: software-driven edge-following algorithm generates continuous point clouds along user-defined boundaries
• Integrated 2D reverse engineering workflow: exported DXF/SVG profiles are CAD-ready for import into SolidWorks, AutoCAD, or Fusion 360
• Theoretical CAD overlay functionality: supports import of 2D DXF drawings for feature-based navigation, datum-aligned measurement, and tolerance-driven reporting
• Comprehensive GD&T evaluation engine: computes profile of a line/surface per ISO 1660 and ASME Y14.5, with selectable evaluation methods (least-squares, minimum-zone, maximum-inscribed)
• SPC module compliant with AIAG SPC Manual v2: calculates process capability indices (Cp, Cpk, Cmk), control limits (X̄-R, X̄-S), and generates run charts, histograms, and Pareto plots
• Mosaic mapping mode: stitches multiple high-magnification image tiles into a single georeferenced macro-image (up to 10,000 × 8,000 pixels), preserving coordinate integrity for retrospective annotation and revision tracking
• Customizable report generation: XML-based template editor allows end-users to define field mappings, conditional logic, logo placement, and multi-language localization

Sample Compatibility & Compliance

The PW-AM800 accommodates flat or low-relief parts up to 800 mm × 600 mm × 200 mm (L×W×H) and weighing ≤15 kg. Compatible sample materials include metals, ceramics, injection-molded plastics, PCBs, and thin-film substrates—provided surface reflectivity permits stable edge contrast. All measurements adhere to ISO 10360-7 (coordinate measuring machines) and VDI/VDE 2634 Part 3 (optical measuring systems). The system supports audit-ready documentation for GLP and GMP-regulated industries, including full measurement history logs with operator ID, timestamp, environmental sensor readings, and calibration certificate references. Firmware and software comply with IEC 62304 Class B for medical device software lifecycle management.

Software & Data Management

The proprietary PW-MeasureSuite v5.2 software runs on Windows 10/11 (64-bit) and features role-based access control, electronic signature support per FDA 21 CFR Part 11, and encrypted local database storage (SQLite with AES-256). Measurement data exports to industry-standard formats: CSV (for statistical analysis), DXF (for CAD integration), PDF/A-2 (archival reports), and XLSX (with embedded pivot tables and dynamic charting). Audit trails record all configuration changes, measurement executions, and report generations—including IP address, workstation ID, and cryptographic hash verification. Raw image archives are stored with EXIF metadata (lens focal length, exposure time, gain settings) to support metrological traceability.

Applications

• Dimensional validation of machined components (pins, bushings, connectors) against GD&T callouts
• First-article inspection for automotive stampings and aerospace sheet-metal parts
• PCB solder paste inspection and component footprint verification
• Tooling wear analysis via periodic profile comparison using baseline mosaic maps
• Reverse engineering of legacy parts lacking CAD models, supporting rapid prototyping workflows
• Statistical process monitoring in high-volume production lines (e.g., consumer electronics housings)
• Educational metrology training for mechanical engineering and manufacturing technology programs

FAQ

What calibration standards are required for ISO 17025 accreditation?
A certified glass scale (e.g., Mitutoyo GS-1000) and traceable step gauge must be used quarterly; annual third-party verification by an ILAC-accredited lab is recommended.
Does the system support automated measurement sequence programming?
Yes—PW-MeasureSuite includes a scriptable macro language (PWScript) compatible with VB.NET syntax for unattended batch measurement routines.
Can measurement data be integrated into MES or ERP platforms?
Via RESTful API endpoints and OPC UA server module (optional add-on), enabling real-time data push to SAP QM, Siemens Opcenter, or custom SQL databases.
Is thermal drift compensation available?
The system does not include active temperature compensation; users must maintain laboratory temperature within ±1 °C of 20 °C during critical measurements.
What is the recommended maintenance interval for optical components?
Annual cleaning and alignment verification of telecentric lens and LED illumination modules by certified PW service engineers is advised.
