Abstract
The DBB (Double Ball Bar) method is able to analyze motion errors of a machine tool in the un-loaded condition. However, the method cannot be applied in the loaded condition. Researches on machining error analyses proposed so far have successfully obtained precise estimation results, but applications of such analyses are extremely limited. In order to realize high accuracy machining, it is necessary to identify the factors of machining errors in the loaded condition and eliminate these errors from machined parts. The objective of this study is to develop a system to analyze and identify the error factors of machining by comparing the measurement data of a machined part with CAD data. The usefulness of the developed system was verified through tests.
