Abstract

The ideal output of operational sequencing of CAPP should include all start and end coordinates of tool movement for all operational dimensions rather than just give dimensions and toleraces unrelated to the coordinate system on the NC machine and leave additional work for the NC programmers. This paper deals with a new method of analysis of Operational Dimension and Tolerance Chain (ODTC) for CAPP systems. Based on discussion of previous works, apparent shortcomings are discussed and an extended approach provides ODTC to generate operational dimensions and tolerance for NC machines as a part of the decision methodology of CAPP systems.
