Optimal Position for Thin-Walled Curved Surface Part in Array-Type Fixture

An optimization on Thin-walled Curved Surface Part (TCSP) position is proposed in order to meet the increasing flexibility need of airplane, automobile industry etc. The position process comes down to coordinate transformation problem. A method based on Oriented Bounding Box (OBB) iteration for TCSP position in array-type fixture is proposed to solve parameters of part coordinate transformation matrix, and comparisons between OBB and OBB iteration is shown. The calculation example shows that the proposed method is feasible, and can effectively solve position parameters of the TCSP position process.
