概要

A series of papers presents a new calibration method particularly for up to a middle size CMM. The method is able to provide the 21 parametric errors only by performing the coordinate comparison. An automated calibration system for the production stage of CMMs is realized. The first report describes basic structure of the linear parameter model which establishes relation between spatial displacement deviation observed by the coordinate comparison and the linearly combined parametric error components of the CMM. A simulation on a simple guide way example with six independent freedoms is performed to verify functionality of the model. The result shows that 96 parameters expressing six parametric errors are possible to be handled simultaneously. It is confirmed that the parametric errors are estimated with sufficient resolution to apply the model to the calibration of CMMs.
