In-Process or Post-Process Metrology?

  • W. N. Clark


The problems of utilising in-process and post-process metrology techniques are examined, and are shown to be either fundamental or ones of application. Error sources in the total system are considered in detail and corrective techniques suggested. It is concluded that if the principle of rationalised closed loop feedback is applied with emphasis on the correction of workpiece errors a new generation of enhanced performance machines can be initiated.
