Abstract

Measurement automation is the essential requirement for metrology at present. It simply eases the measurement procedure and reduces the time to generate report/calibration certificate as well as in establishment of advanced techniques for measurement. Automation improves the measurement uncertainty as it eliminates the human error in measurement. An automation program has been developed for a High Frequency LCR Meter.

Abstract

Metrology applications require surface plates of high accuracy and stability Surface plates are made in different sizes, shapes and with different materials. The most common shape is rectangular and the most common material is steel or granite. The accuracy of the surface is obtained by repeated measurements and by lapping the non-flat regions. In this paper, an attempt has been made to analyze the circular surface plates to reduce its weight and optimize the deflection by different support locations and different types of ribbing.
