TLDR
In this paper, two models were created for the verification of CAFDV, one geometric and one kinematic, for both modular fixtures and dedicated fixtures, and they were used to verify the following properties: geometric constraining ability, achieved tolerance, fixturing stability, and accessibility.Abstract:
Computer‐aided fixture design (CAFD) techniques have been advanced so rapidly that computers can now generate fixture configurations automatically, for both modular fixtures and dedicated fixtures. Computer‐aided fixture design verification (CAFDV) is the techniques for verifying and improving existing fixture designs. It verifies the followings: geometric constraining ability, achieved tolerance, fixturing stability, and fixturing accessibility. Two models – one geometric and one kinematic – are created for the verification.read more
