Dimensional measurement and evaluation of intricate features using tactile-optical micro-probes on coordinate measuring machines

Abstract:

The miniaturization of parts and components and the growing demand for more accurate measurements have led to ongoing developments in the field of dimensional metrology. Coordinate metrology as a multipurpose and an efficient measurement technology, has been widely used in the industrial sector, and thus deserved considerable efforts to extend its capabilities to new engineering needs impelled by the market. Most developments have involved new probing solutions which have made possible to engineers defining new dimensional engineering parameters. This paper deals with the matter of measuring intricate geometries on multi-port fuel injectors using coordinate measuring machines with multiple sensors. The dimensional engineering needs related to those geometric, the measurement problem and the experimental findings are outlined and discussed under a metrology perspective. Particular attention is given to the measurement setup and traceability to the SI.
