Project description
With raising demand for “virtual measurements” in measurement uncertainty estimation also the demand for uniform and systematic processes for the development of long-living and complex, though industry-ready simulation software increases. Within the competence center “Metrology for Virtual Measuring Instruments” (
VirtMet), PTB addresses these issues in collaboration with various projects from different metrological fields.
We regard the well-established and pioneering “Virtual Coordinate Measuring Machine” VCMM as suitable reference application. The VCMM is used to determine the task-specific measurement uncertainty through a virtual representation of the measurement process by a Monte Carlo Simulation. As part of VirtMet, the VCMM principles will be generalized and the experience will be transferred to allow for further applications in the industrial environment.
A software library comprising the components required to successfully build a reliable simulation software will be crated and tested in selected applications. In a first step, the method will be transferred to the “Virtual Planck Balance” (VPB). In a second step, the software library will successively be generalized to enable the implementation of additional virtual measurement instruments.
