In recent years, the CMM (Coordinate Measuring Machine) quickly has been spreading in the manufacturing industry. With this phenomenon, the environmental condition and installation site of CMMs has been changed from the temperature control room to the workshop environment and the production line without air conditioning. However, even in severe environment the demand to high accuracy measurements by CMM has been enhancing still more. Therefore, the methods to evaluate and realize the high accuracy measurements by CMM in workshop environment have been investigated. In this paper, we evaluated the influence of measurement error of indication within form, size and location errors by articulating probing system. Furthermore, we experimentally tested the influence of measurement error of indication within form, size and location errors, and proposed the method to evaluate location errors with the value of the squareness error of the position of the reference sphere and the position of measurement.
