Paper Abstract

An entire set of measurement scheme was designed to measure a granite rectangular square of (2000×1600) mm in size. Each angle was measured separately using the squareness measurement system, and data processing was then carried out using closure principle. A dedicated slider with air-bearing was also designed to obtain more stable and reliable data.
