Introduction
Quality control is one of the important parts of production process which can be
performed trough many possible ways with different measuring gauges and equipment. New
products following the trends of designers or requirements of industrial applications with
freeform surfaces require instruments with high ability of measuring tasks solving. Regarding
many advantages of On-machine measurement system, the utilization of the systems has
become a subject of many researches. These systems allow controlling the parts directly on
the machine tool, and also the process can be integrated directly to the machining process
whereas the delays from transportation and measuring process performed on coordinated
machine are omitted.
