| Zusammenfassung | Sculptured furfaces respresent the most difficult measuring tasks for coordinate measuring machines (CMMs). Measuring uncertainty in such task may be 2-10 times higher than that of length measurements. Up to now there has been very little evidence on the performance of CMMs in tasks more complex than e.g. simple length measurements. Virtual coordinate measuring machines (VCMM) concept lately developed at PTB facilitates the prediction of task-specific measuring uncertainty in practically any measurement. The current paper tells about the first application of the method for double curved surfaces, namely for a demanding spiral bevel gear measurement. The results are compared to those resulting from a comparison among some of Europe's reference CMMs. The superiority of the VCMM method over classic uncertainty assessment by substitution method lies in its generality, radically reduced costs of reference standards and better prediction of uncertainties. |
