Dual Sensor 3D Measurement Boosts Accuracy and Efficiency in Sheet Metal Manufacturing
Stahl Lasertechnik GmbH, a German specialist in metal sheet processing, has significantly upgraded its quality control processes by integrating Kreon 3D measurement solutions. Facing challenges in maintaining high-precision inspection and detecting deformation defects in complex assemblies, the company sought an advanced solution for First Article Inspection (FAI), process optimization, and comprehensive part measurement management.
To address these needs, the Quality Management Team at Stahl Lasertechnik implemented the Kreon Ace+ 3.50 measuring arm paired with the Skyline Eyes 3D scanner and PolyWorks metrology software, resulting in a more accurate, efficient, and flexible quality workflow.
Dual Sensor Arm Delivers Precise Analysis
The integration of the Kreon Ace+ measuring arm and Skyline Eyes 3D scanner allows Stahl Lasertechnik to combine contact probing with non-contact 3D scanning for precise analysis of Geometric Dimensions and Tolerances (GD&T).
Initially, engineers used the Kreon arm to inspect individual parts and refine manufacturing processes. Over time, 3D scanning was routinely combined with traditional probing to maximize efficiency and measurement accuracy. To further improve flexibility, the company plans to add a rolling trolley, allowing the measuring arm to move freely and reach large components directly on the shop floor.
Key benefits of portable arm measurement system include:
- Probing and scanning for both large and small components
- Quick, seamless transition between probing and scanning
- Portable design for shop-floor mobility and space-saving
- Comprehensive inspection of parts’ shapes and tight tolerances
- Detailed deformation and freeform shape analysis
Overcoming Limitations of Previous Systems
Previously, Stahl Lasertechnik relied on legacy 3D measurement systems. Over time, these systems exhibited degraded performance, leaving QA engineers struggling to:
- Accurately inspect large metal sheets and complex assemblies
- Detect deformations from bending and welding processes
- Conduct First Article Inspections efficiently
- Analyze freeform shapes
After researching alternatives, Stahl Lasertechnik connected with Kreon Technologies, where experts provided a hands-on demonstration tailored to the company’s specific needs. Kreon offered personalized technical support, highlighting the system’s precision, ease of use, and mobility.
Streamlining Measurement Programs with PolyWorks
By leveraging PolyWorks Inspection software, Stahl Lasertechnik built a library of measurement data for both existing and new parts. This systematic approach enables ready-to-inspect workflows, ensuring parts meet tolerance requirements consistently.
PolyWorks functionality enables:
- CAD model alignment for deviation analysis
- Color map generation for clear visualization of geometric differences
- Efficient FAI reporting and long-term data storage
This approach also improves collaboration with clients. After the inspection of a first part, the measurement file—including methods and tolerances—is sent to customers for review, validation, or modification before full-scale production.
“During the demonstration and subsequent training, the Kreon experts explained everything comprehensively and answered all our questions, demonstrating excellent pedagogical and technical competence” commented Slawa Korb, Head of Quality Management, Stahl Lasertechnik.
A Clear Step Forward in Quality Assurance
The integration of Kreon 3D measurement solutions has enabled Stahl Lasertechnik to enhance precision, reduce inspection time, and improve process efficiency, particularly in complex sheet metal manufacturing. By combining portable 3D scanning, probing, and advanced software analytics, the company has established a robust quality control workflow that is both accurate and adaptable, strengthening its competitive position in high-precision manufacturing.
