Difference between GRR and LRS

Question

Accepted Answer

GRR and LRS are statistical methods used in engineering for different purposes.

GRR stands for Gauge Repeatability and Reproducibility, which measures the variation in measurement systems.
LRS stands for Linearity, Repeatability, and Stability, which measures the performance of a measurement system over time.
GRR focuses on the measurement system's ability to provide consistent and repeatable results.
LRS focuses on the measurement system's linearity, repeatability, and stability over a period of time.
GRR is commonly used in industries like manufacturing to assess the reliability of measurement systems.
LRS is often used in fields like metrology to evaluate the long-term performance of measurement systems.

Accepted Answer

The major difference between them

Lrs is used where no need to control speed and high starting torque is required.

I.e. Ball mills

Grr is used for speed control of slipring motor. I.e fan
