    Up to now, machining process is judged mainly by the post-process measurement of the completed part. The occurrence of reject indicates that there had been some problems in the machining process, but it's usually difficult to determine where the problems “source” is. Making parts by measuring and adjusting process parameters instead of measuring a completed part will be able to transfo... View full abstract»
