CHOTEST VX8000 Series One-Touch Flash Measurement System

Overview

The CHOTEST VX8000 Series One-Touch Flash Measurement System is a high-throughput, non-contact optical metrology instrument engineered for rapid, automated two-dimensional geometric dimensioning and tolerancing (GD&T) inspection of manufactured parts. It operates on the principle of telecentric imaging combined with sub-pixel edge detection algorithms and programmable measurement logic—enabling true one-button operation without manual alignment, fixture setup, or operator-dependent focusing. The system employs a high-resolution dual-telecentric lens paired with a 20-megapixel CMOS sensor to capture distortion-free, magnification-stable images across its full 300 mm × 200 mm field of view. In CNC mode, the instrument autonomously identifies part geometry via real-time image segmentation, matches against preloaded CAD templates or user-defined feature libraries, executes calibrated measurements, evaluates dimensional conformance per ISO 1101 and ASME Y14.5 standards, and generates traceable inspection reports—all within seconds of initiating measurement.

Key Features

• One-touch automated measurement: Eliminates reliance on mechanical fixturing; parts may be placed freely on the stage with automatic pose recognition and template matching.
• High-capacity parallel measurement: Supports simultaneous evaluation of up to 1,024 geometric features per image frame.
• CAD-driven inspection: Accepts industry-standard DXF and STEP files; automatically registers part geometry and populates measurement routines based on nominal dimensions and GD&T callouts.
• Sub-pixel edge analysis: Achieves <1% pixel-level resolution through advanced interpolation and noise-resistant contour extraction algorithms.
• Auto-focus repeatability: Motorized Z-axis focus control ensures consistent depth-of-field positioning across repeated inspections—critical for inter-operator and inter-shift measurement stability.
• Robust coordinate management: Supports multiple reference systems—including instrument, workpiece (point-line, two-point X, two-line), and image-registration coordinates—with full translation, rotation, and manual fine-tuning capabilities.

Sample Compatibility & Compliance

The VX8000 accommodates flat or low-relief components with maximum dimensions of 300 mm × 200 mm and weight ≤7.5 kg. Its telecentric optical path ensures minimal perspective error, making it suitable for thin stamped metal parts, PCBs, gaskets, O-rings, connector housings, and precision-machined plates. Optional height-sensing modules (e.g., non-contact optical probe) extend functionality to planarity, step height, and surface profile assessment. The system complies with ISO/IEC 17025 requirements for calibration traceability and supports GLP/GMP-aligned audit trails when configured with optional secure user authentication and electronic signature modules. Measurement uncertainty budgets are documented per ISO/IEC 14253-1 and validated using certified gauge blocks and ring gauges traceable to NIM (China National Institute of Metrology).

Software & Data Management

CHOTEST’s proprietary VisionMetro software provides an intuitive GUI with drag-and-drop workflow configuration, no-code scripting for custom inspection sequences, and native SPC integration. It includes over 80 built-in geometric extraction tools—including R-angle analysis, pitch measurement (linear/circular), spring coil counting, and contour comparison against master profiles. All measurement data—including raw images, edge maps, coordinate transformations, and tolerance evaluations—is stored in a structured SQLite database with timestamped metadata. Export options include CSV, PDF, XML, and industry-standard Q-DAS QDB format. Remote data access is supported via HTTPS-based REST API, enabling integration into MES, SCADA, and quality analytics platforms. Software validation documentation (IQ/OQ/PQ protocols) and 21 CFR Part 11 compliance packages are available upon request.

Applications

The VX8000 is deployed extensively across high-volume manufacturing sectors where speed, repeatability, and ease of use are critical: automotive stamping and connector assembly; consumer electronics (FPC, camera modules, battery terminals); medical device components (catheter hubs, surgical instrument blanks); watch movement parts; precision mold inserts; and printed circuit board solder paste inspection. Its ability to replace manual optical comparators and reduce CMM cycle times makes it especially valuable in first-article inspection, in-process verification, and final lot acceptance testing environments.

FAQ

What types of geometric features can the VX8000 measure?
It measures points, lines, circles (center, radius, diameter), arcs, angles, distances, widths, hole positions and sizes, linear and circular pitches, intersections, centroids, and derived constructs such as tangents, perpendiculars, bisectors, and best-fit geometries.
Does the system support GD&T evaluation?
Yes—it evaluates straightness, flatness, circularity, cylindricity, profile of a line/surface, position, symmetry, perpendicularity, concentricity, and parallelism per ISO 1101 and ASME Y14.5.
Can measurement programs be reused across different parts?
Yes—programs are parameterized and modular; CAD-based templates allow rapid adaptation to new parts sharing similar feature families or datum structures.
Is external calibration required?
The system includes internal calibration routines using certified reference artifacts; however, periodic third-party verification per ISO 10360-7 is recommended for accredited labs.
What operating system and hardware requirements does the software require?
VisionMetro runs on Windows 10/11 (64-bit), requires ≥32 GB RAM, ≥1 TB SSD storage, and an NVIDIA GPU with ≥8 GB VRAM for real-time image processing.
