Tolerance chain design and analysis of in-process workpiece

Process planning comprises a broad range of activities to define a complete process chain for the manufacturing of a product. Beside the definition of proper operations and operation sequence, the definition of in-process tolerances for multi-step machining is decisive for the possibilities to achieve a well running and economical production. This paper introduces the dimension dependency chart (DDC) as a methodology based on tolerance charting technique where the complete manufacturing process chain can be efficiently represented, analysed and developed. The DDC uses mapping matrices for the transformation of operation element behaviour to the process steps defined by the process planner and further on to the dimensions and tolerances for the final part. Two important comparisons can be done by using the DDC; the expected behaviour of the in-process steps versus the tolerances defined by the process planner and the allowed variations of the final part dimensions versus the designed product specification.
