Rational DMIS software integrates CAD, thin-walled part and scanning modules, capable of meeting customers’ ever-growing measurement demands.

As the core intelligent software in the field of coordinate measuring machine (CMM) metrology, Rational DMIS acts as a critical medium connecting measurement hardware and customer requirements by virtue of its modular design and standardized compatibility. Its integrated CAD, thin-walled part and scanning modules generate synergistic advantages to precisely respond to the increasingly diversified, high-precision measurement requirements in high-end manufacturing. Meanwhile, the software strictly complies with DMIS and I++ protocol standards and has obtained German PTB certification, ensuring the universality, reliability and authority of the entire measurement workflow.

CAD Module: Enabling End-to-End Digital Collaboration. It breaks down data silos between design and inspection, supports seamless interfacing with CAD files, and can automatically identify nominal elements from digital models and rapidly generate measurement programs without manual programming, greatly simplifying the measurement preparation process for standard parts such as gears and gauge blocks. With a drag-and-drop user interface, operators can intuitively complete measurement path planning, model comparison and deviation analysis. It also supports real-time data synchronization and sharing, realizing full-process collaboration from product design, machining to precision inspection, and adapting to the demands of digital quality control.

Thin-Walled Part Module: Solving Measurement Pain Points of Deformation-Prone Components. For thin-walled standard parts and components applied in aerospace and new energy vehicles, the module delivers targeted optimizations to measurement algorithms and force control logic, effectively eliminating part deformation caused by contact pressure and clamping forces encountered in conventional measurement. By reducing probe-to-part contact frequency through intelligent path planning, combined with dynamic error compensation technology, it accurately captures dimensional tolerances and geometric deviations of thin-walled parts, ensuring measurement accuracy is unaffected by part structural characteristics, and filling the gap in high-precision measurement of fragile and deformation-prone workpieces.

Scanning Module: Balancing High Efficiency and Full-Dimension Data Acquisition. Compatible with both contact and non-contact scanning modes, it allows flexible switching according to different structures (e.g., gear tooth spaces, bearing inner rings) and materials (e.g., ceramics, hardened gear surfaces). It can perform rapid scanning of the full gear profile as well as parameter acquisition in complex areas inaccessible with traditional methods. Supporting multi-length stylus adaptation, path simulation and collision detection, the scanning efficiency is improved by more than 60% compared with conventional single-point measurement, while ensuring completeness and security of data acquisition, providing efficient data support for scenarios such as gear standard part certification and heavy-duty gearbox inspection.

The collaborative integration of the three modules enables Rational DMIS software to adapt to full-scenario measurement demands ranging from precision standard parts to large, complex components. It not only strengthens the accuracy and efficiency advantages of coordinate measuring machines, but also reduces enterprise manpower training costs through simplified operation and expanded functions, serving as the core software support to fulfill customers’ personalized and high-end measurement requirements.
