Faculty Research Predicting Assembly Dimenions With Funcational Build
نویسندگان
چکیده
When using the functional build approach to manufacturing validation during new product development, manufacturers use pre-production assemblies to evaluate whether components within an assembly may build dimensionally correct products. This approach allows some individual component characteristics to not meet their original design specifications, provided the resultant assembly meets its requirements. In applying this functional build methodology, manufacturers assume that the pre-production assemblies provide data representative of what the manufacturer will encounter in the regular production process. This paper evaluates the predictive validity of the functional build approach by utilizing a design of experiment to examine the effect of two factors-build fixture and method of attachment-in constructing functional build pre-production assemblies of stamped sheet metal components. The results confirm the importance of using assembly fixtures that closely resemble regular production processing.

Background The underrepresentation of minority students in the sciences constrains innovation and productivity in the U.S. The SF BUILD project mission is to remove barriers to diversity by taking a "fix the institution" approach rather than a "fix the student" one. SF BUILD is transforming education, research, training, and mentoring at San Francisco State University, a premiere public univers...
متن کاملA chance-constrained multi-objective model for final assembly scheduling in ATO systems with uncertain sub-assembly availability
A chance-constraint multi-objective model under uncertainty in the availability of subassemblies is proposed for scheduling in ATO systems. The on-time delivery of customer orders as well as reducing the company's cost is crucial; therefore, a three-objective model is proposed including the minimization of1) overtime, idletime, change-over, and setup costs, 2) total dispersion of items’ deliver...
