Abstract

In industry, the Coordinate Measuring Machine (CMM) is a major geometrical measurement method because of its precision and general versatility. The CMM is conventionally used in a thermostatic chamber, but its use in the production line environment is increasing. Many factors – dust, thermal fluctuation, and collision, to name a few – deteriorate measurement precision and make it necessary to inspect the CMM daily. However, the daily inspection method is not established. Study of CMM is mainly about calibration in controlled environment like a thermostatic chamber. It is unfeasible to calibrate the CMM everyday because of its cost. So some researchers have studied about daily inspection of CMM. This paper describes daily CMM inspection procedures and how to evaluate these uncertainty. This method treats axis scale errors and interaxis squareness errors from geometric errors of CMM. These factors influence the measurand. QuickCheck (Trapet Precision Engineering) is used as an artifact. In the linear model using QuickCheck, influences of alignment error is evaluated parameters.
