The applied procedures for determining the capability of the measuring system and measurement process experimentally use workpieces from production. In most cases, it is not feasible to transfer a calibrated workpiece to the production line ahead of the inline measuring station and to measure it subsequently. Thus you have got the option to take workpieces from the process after they passed the inline measuring station and to calibrate them on a coordinate measuring machine. If there are not any workpieces from series production available yet, you may use measurement standards in the start-up phase and calibrated workpieces from pre-series production in the pre-series phase.
