Accretech XYZAX Series Precision Coordinate Measuring Machine

Overview

The Accretech XYZAX Series Precision Coordinate Measuring Machine is an industrial-grade, shop-floor compatible CMM engineered for high-reproducibility geometric metrology in demanding manufacturing environments. Built upon a rigid granite or stabilized aluminum alloy base structure—depending on model configuration—the XYZAX platform integrates Tokyo Seimitsu’s precision mechanical architecture with Carl Zeiss’ proprietary control electronics and VAST XT active scanning probe technology. Its measurement principle follows the Cartesian coordinate system, where orthogonal X-, Y-, and Z-axis motion systems (driven by high-resolution linear encoders and servo-controlled DC motors) precisely position a tactile probe within a defined volumetric workspace. The system captures discrete point clouds or continuous surface profiles, which are then processed using traceable algorithms compliant with ISO 10360 and JIS B 7440-2:2003 to compute dimensional, form, orientation, and location tolerances per GD&T standards (ASME Y14.5 / ISO GPS). Unlike laboratory-grade CMMs, the XYZAX Series is specifically designed for integration into production cells—featuring thermal drift compensation, vibration-damped kinematics, and sealed guideways rated for ambient temperature fluctuations between 16 °C and 26 °C.

Key Features

• Hybrid Guideway Architecture: XYZAX mju NEX and SVA NEX models utilize a mixed-material rail system combining ceramic-coated steel and low-expansion aluminum alloys to minimize thermal deformation and reduce power consumption by up to 22% versus conventional air-bearing CMMs.
• VAST XT Active Scanning Probe: Integrated as standard on FUSION NEX and SVA Fusion variants, this dynamic probe maintains constant tip force perpendicular to the measured surface during high-speed scanning—enabling MPETHP ≤ 2.1 µm (FUSION NEX) and ≤ 2.8 µm (SVA NEX) under ISO 10360-4 verification protocols.
• AI-Assisted Measurement Workflow: Proprietary AI pattern recognition engine (internationally patented by Accretech) automatically identifies nominal geometry from CAD models or sketch inputs, auto-generates inspection routines, and validates feature alignment—reducing programming time by >40% and enabling operator-level users to execute complex GD&T evaluations without prior metrology training.
• Real-Time Environmental Compensation: Standard onboard temperature sensors (X/Y/Z axis + workpiece proximity) feed data to a multi-point thermal model that dynamically adjusts measurement results per ISO 230-3, ensuring MPE_E remains within specification across the full operating range (1.6 + 3L/1000 µm for FUSION NEX; 1.8 + 4L/1000 µm for SVA NEX).
• Shop-Floor Ergonomics: Patented dual-side guided granite table with spring-damped rigidity, tactile LCD touchscreen interface (10.1″, glove-compatible), Z-axis confirmation button for hands-on continuous probing, and fine-adjustment knobs on all three axes support rapid setup and repeatable operation in non-climate-controlled production areas.

Sample Compatibility & Compliance

The XYZAX Series accommodates parts ranging from miniature components (e.g., medical implants, MEMS housings) up to large castings and welded assemblies (max. envelope: 900 × 1000 × 600 mm for SVA NEX 9/10/6). It supports interchangeable probe modules—including star, disc, and extension configurations—with standard 300 mm extension rods certified to maintain MPETHP ≤ 5.8 µm. All models comply with ISO 10360-2 (length measurement error), ISO 10360-4 (scanning performance), ISO 15530-3 (CMM-based calibration), and JIS B 7440-2:2003. Full 21 CFR Part 11 compliance is achievable via optional CALYPSO Audit Trail Module, including electronic signatures, change logs, and role-based access control—validated for pharmaceutical, aerospace, and automotive Tier-1 quality systems requiring GLP/GMP documentation.

Software & Data Management

CALYPSO v7.8 (licensed from Carl Zeiss) serves as the native metrology software platform, supporting ISO GPS syntax, PMI-driven inspection, statistical process control (SPC) charting, and automated report generation in PDF, Excel, or XML formats. The AI-assisted routine builder interfaces directly with common CAD kernels (Parasolid, STEP AP242), enabling automatic GD&T extraction and tolerance-aware path planning. Raw point cloud data is stored in vendor-neutral ASCII or Zeiss-specific .CMM formats; all measurement sessions include timestamped metadata, environmental parameters, probe calibration history, and user authentication logs. Optional DataBridge module enables direct integration with MES/ERP systems (Siemens Opcenter, SAP QM) via OPC UA or RESTful API.

Applications

The XYZAX Series delivers traceable dimensional verification for high-value manufactured parts across regulated and high-precision sectors: turbine blade root geometry and airfoil profile validation in aerospace; camshaft lobe form and journal roundness in automotive powertrain; orthopedic implant surface texture and taper angle conformity in medical device manufacturing; semiconductor package coplanarity and lead pitch in electronics assembly; and mold cavity fidelity assessment in injection molding tooling. Its shop-floor resilience makes it suitable for first-article inspection, in-process gaging, and final acceptance testing—all within a single validated platform.

FAQ

What is the maximum permissible error (MPE) for the XYZAX SVA NEX 7/5/5 model?
MPE_E = 1.8 + 4L/1000 µm, verified per ISO 10360-2 Annex D using calibrated step gauges and sphere artifacts.
Does the system support automated calibration of probe qualification artifacts?
Yes—CALYPSO includes automated sphere, disk, and ring artifact calibration routines compliant with ISO 10360-5, with full uncertainty budgeting per GUM (JCGM 100:2008).
Can the XYZAX operate without climate control in a production environment?
It is rated for stable operation between 16 °C and 26 °C with full thermal compensation; however, long-term accuracy stability beyond ±1 °C/hour ambient drift requires supplemental HVAC or localized enclosure.
Is FDA 21 CFR Part 11 compliance available out-of-the-box?
No—Part 11 functionality requires activation of the optional CALYPSO Audit Trail License and configuration by an Accretech-certified metrology specialist.
What CAD file formats are natively supported for offline programming?
STEP AP203/AP214, IGES, Parasolid (.x_t/.x_b), and native CATIA V5/V6 files; neutral mesh import (STL/OBJ) is supported for reference geometry only.
