Dantsin Scopecheck MB Mobile Bridge Hybrid Optical CMM

Overview

The Dantsin Scopecheck MB is a mobile bridge-type hybrid coordinate measuring machine engineered for high-precision, non-contact dimensional metrology in demanding production environments. Designed to meet the rigorous requirements of modern shop-floor quality control, it integrates telecentric optical imaging with optional tactile probing capabilities—enabling traceable, multi-sensor measurement of complex geometries without part deformation or surface damage. Its core architecture features a monolithic granite base for exceptional thermal stability and vibration damping, paired with precision air-bearing linear motion systems that ensure sub-micron repeatability across its full volumetric envelope. The system operates on the principle of calibrated image-based edge detection under parallel illumination, delivering true orthographic projection geometry essential for GD&T evaluation—including position, profile, flatness, and concentricity—per ISO 1101 and ASME Y14.5 standards. Unlike traditional CMMs constrained to climate-controlled labs, the Scopecheck MB is thermally compensated and mechanically hardened for operation in ambient workshop conditions, maintaining metrological integrity at 20 ± 1 °C with thermal drift controlled to ≤ 0.5 K/h.

Key Features

• Modular mobile bridge design with integrated cast-iron structural frame and precision-ground granite base for long-term geometric stability
• Air-bearing guideways on all three axes, enabling smooth, frictionless motion and eliminating stick-slip errors during high-speed scanning
• Patented parallel-beam telecentric illumination system ensuring zero perspective distortion and consistent magnification across the entire field of view
• Removable bottom-light module supporting transmitted-light edge detection for transparent, semi-transparent, or thin-sectioned components
• Hybrid sensor compatibility: native integration of high-resolution digital cameras (up to 29 MP), optional touch-trigger or scanning probes (PH10M/TP20 equivalents), and laser line scanners
• Real-time thermal compensation using embedded temperature sensors aligned with ASTM E2921-22 guidelines for in-situ environmental correction
• IP54-rated enclosure options available for particulate- and coolant-resistant operation in machining cells

Sample Compatibility & Compliance

The Scopecheck MB accommodates parts ranging from small machined inserts (<50 mm) to large structural assemblies (up to 3 m in Y-direction), including castings, sheet metal fabrications, composite tooling, and injection-molded housings. Its non-contact methodology eliminates mechanical loading effects, making it ideal for soft materials (e.g., elastomers, foams), delicate optics, and heat-sensitive components. The system conforms to ISO 10360-2 (CMM performance verification), ISO 15530-3 (calibration using calibrated workpieces), and VDI/VDE 2617 Part 9 (optical CMM testing procedures). It supports full audit trails compliant with FDA 21 CFR Part 11 when deployed with validated software configurations, and meets GLP/GMP documentation requirements for regulated manufacturing sectors including automotive Tier-1 suppliers and medical device OEMs.

Software & Data Management

Equipped with Dantsin MetroSuite v5.x, the Scopecheck MB provides unified programming, acquisition, and reporting workflows. The software features CAD-based alignment (supporting STEP, IGES, and native SolidWorks/Creo imports), automated GD&T evaluation per ASME Y14.5–2018, and statistical process control (SPC) export to Minitab, JMP, or enterprise MES platforms via OPC UA or SQL Server connectivity. All measurement data—including raw images, coordinate point clouds, and calibration logs—is timestamped, digitally signed, and stored in an encrypted local database. Revision-controlled report templates comply with ISO/IEC 17025 documentation protocols, and electronic signatures are enforced for operator authentication and result approval.

Applications

• In-process verification of large aerospace wing ribs and fuselage frames
• First-article inspection of automotive body-in-white components (e.g., door inner panels, floor crossmembers)
• Dimensional validation of additive-manufactured titanium brackets prior to HIP treatment
• Tooling certification for composite layup molds in wind turbine blade production
• GD&T compliance checks on medical implant housings requiring surface finish preservation
• Reverse engineering of legacy parts where contact probing risks damage or distortion

FAQ

Is the Scopecheck MB suitable for unattended overnight operation?
Yes—when installed with optional environmental monitoring and power-fail recovery modules, it supports scheduled autonomous measurement cycles with full error logging and email alerting.
Can tactile probes be retrofitted to an optical-only configuration?
Yes—the MB platform includes standardized kinematic probe mounts and controller interfaces compatible with industry-standard analog and digital probe systems.
What calibration artifacts are required for routine verification?
A certified step gauge, ball bar, and ceramic sphere standard (ISO 10360-5 compliant) are recommended for daily performance checks; annual full volumetric calibration follows ISO 10360-2 Annex B protocols.
Does the system support real-time SPC charting on the shop floor display?
Yes—MetroSuite includes embedded X-bar/R and Cpk dashboards with configurable alarm thresholds and direct PLC interface for line-stop signaling.
How is thermal drift managed during extended measurements?
Embedded thermal sensors feed into a real-time compensation algorithm based on material-specific expansion coefficients and spatial gradient modeling, referenced to the granite base’s intrinsic thermal inertia.
