RS-200 Residual Stress Milling Guide | Micro-Measurements

The RS-200 Residual Stress Milling Guide is a critical tool for accurately measuring residual stresses using the widely recognized hole-drilling strain gage (gauge) method, as outlined in ASTM Standard E837. This practical and precise technique is essential for engineers and professionals involved in stress analysis, helping to ensure accuracy and reliability in their measurements.

How It Works:

The hole-drilling strain gage (gauge) method involves bonding a specially configured electrical resistance strain gage (gauge) rosette to the surface of the test object. A small, shallow hole is then drilled through the center of the rosette.
The local changes in strain caused by introducing the hole are measured, and from these measurements, the relaxed residual stresses are computed.

The Importance of Precision:

The accuracy and effectiveness of the hole-drilling method depend heavily on the precision of drilling the hole at the exact center of the strain gage (gauge) rosette. The Micro-Measurements RS-200 Milling Guide provides an easy-to-use, practical solution to ensure this high level of precision, directly contributing to the overall success of the stress measurement process.

Key Features:

Precision Drilling: The RS-200 guide ensures that the hole is drilled with the highest accuracy, minimizing errors and enhancing the reliability of residual stress measurements.
Practical Application: Specifically designed for use with the hole-drilling method, the RS-200 is ideal for professionals seeking dependable tools for stress analysis.
Compatibility with ASTM Standards: Compliant with ASTM Standard E837, the RS-200 aligns with industry best practices, ensuring that your measurements meet recognized standards.
