For PI, each individual measurement and qualification is an instrument for quality assurance. This makes sure that only those positioning systems leave the premises that are within the guaranteed specifications. All measurements are made with external, verifiable measuring equipment such as high-resolution interferometers.
The qualification data is verifiable for each individual product. The measurement data is compiled in a database and used for process control. Retraceability at product level is particularly interesting for large production runs.
The measurement log is provided with many systems such as hexapods or piezo systems. It is therefore possible for the customer to verify the performance of the system with the data measured before it was dispatched and also see which system components belong together.
