Inertia compensation while scanning screw threads on coordinate-measuring machines

摘要

Usage of scanning coordinate-measuring machines for inspection of screwthreads has become a common practice nowadays. Compared to touch triggerprobing, scanning capabilities allow to speed up measuring process while stillmaintaining high accuracy. However, in some cases accuracy drasticaly dependson the scanning speed. In this paper a compensation method is proposed allowingto reduce the influence of some dynamic effects while scanning screw threads oncoordinate-measuring machines.
