Measurement of large-size casting geometry of the CMM
Journal Title: Archiwum Odlewnictwa - Year 2011, Vol 11, Issue 2
Abstract
The aim of this paper is to present the geometric dimensions’ control of large castings and moulds on coordinate measuring machines (CMMs). Precise measurements of large components are connected with many problems that arise from the vast mass and dimensions of the element. The bodies with a mass of several or even tens of tons require that the same metrological regime is restricted which is dedicated for small components measurement. That force the use of suitable measuring device, measurement conditions and the adequate preparation of the element. Quality requirements expressed as tolerances in absolute terms do not cause difficulties in measurement. With regard to the significant size of the workpiece, it is not as easy to measure dimensions as with control of small elements. The paper presents the Coordinate Measuring Machines used to control large-size items.
