Metrology and Machine Measurement

Precise Measurement as the Foundation for Quality and Innovation

Metrology is a central element at the Institute of Production Engineering (IFT) to ensure the highest manufacturing quality. Our research focuses on developing, applying, and integrating modern measurement methods to monitor and optimize parts and processes with maximum precision.

We use high-resolution measuring devices, automated inspection systems, and link metrology with digital analysis tools. Combining precise data acquisition with intelligent evaluation provides the foundation for stable processes, reliable quality control, and continuous improvement.

Research Focus Areas:

  • Development and optimization of measurement strategies for complex geometries
  • Inline and offline measurement systems for process monitoring
  • Integration of metrology into automated production workflows
  • Application of ISO-GPS tolerance principles

Precision Starts with the Machine Tool

The accuracy of manufacturing strongly depends on the precision of the machine tools used. At the IFT, CNC machines are measured with state-of-the-art systems to detect deviations early and optimize machine geometry.

Typical measurements include spindle position, runout accuracy, and other geometric parameters crucial for machining quality. Through systematic measurement, machine capability can be evaluated, and optimization measures can be derived.

Research Focus Areas:

  • Geometric measurement of CNC machine tools
  • Analysis of spindle position and runout accuracy
  • Detection of deviations using high-precision laser scanners
  • Derivation of optimization measures to improve manufacturing quality
  • Application and advancement of ISO 230 standards in research and teaching
