1. 1. Process planning for precision manufacturing : An approach based on methodological studies

   Författare :Mats Bagge; Bengt Lindberg; Anders Kinnander; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process planning; precision manufacturing; machining; tolerance chain analysis; process behaviour; process performance; process capability; in-process workpiece.; Production Engineering; Industriell produktion;

   Sammanfattning : Process planning is a task comprising a broad range of activities to design and develop an appropriate manufacturing process for producing a part. Interpretation of the part design, selection of manufacturing processes, definition of operations, operation sequences, machining datums, geometrical dimensions and tolerances are some common activities associated with the task.
