Impact of Fixture Design on Sheet Metal Assembly Variation
This paper presents a new fixture design methodology for sheet metal assembly processes. It focuses on the impact of fixture position on the dimensional quality of sheet metal parts after assembly by considering the effect of part variation, tooling variation and assembly springback. An optimization algorithm combines finite element analysis and nonlinear programming methods to determine the op...
متن کاملParametric Variational Analysis of Compliant Sheet Metal Assemblies with Shell Elements
One of most demanding tasks in the manufacturing field is controlling the variability of parts as it may affect strongly the deliverability of key characteristics defined at the final (product) assembly level. Current CAT systems offer a good solution to the tolerance analysis/synthesis task, but to handle flexible objects with shape errors more effort is needed to include methods able to captu...
متن کاملNear optimal design of fixture layouts in multi-station assembly processes
Near Optimal Design of Fixture Layouts in Multi-station Assembly Processes. (August 2004) Pansoo Kim, B.S., Pusan National University; M.S., Pusan National University Chair of Advisory Committee: Dr. Yu Ding This dissertation presents a methodology for the near optimal design of fixture layouts in multi-station assembly processes. An optimal fixture layout improves the robustness of a fixture s...
متن کاملOptimal Trajectory Planning For Material Handling of Compliant Sheet Metal Parts
One of the most critical issues in the material handling of compliant objects is excessive part deformation. The deformation of compliant sheet metal parts during the handling process can significantly impact both part dimensional quality and production rate. Increasing production rate while maintaining part quality requires an optimal design of the part transfer trajectory. This paper describe...
متن کاملMulti-objective optimal fixture layout design
This paper addresses a major issue in fixture layout design to determine and evaluate the acceptable fixture designs based on multiple quality criteria and to select an optimal fixture with appropriate trade-offs among multiple performance requirements. The performance objectives considered are related to the fundamental requirements of kinematic localization and total fixturing (formclosure). ...
