... of parallelism error reduced by the DSL process was rarely investigated. Furthermore, the relationship between parallelism and flatness was not clearly illustrated. To explain why the parallelism of workpieces becomes convergent by the DSL, a theoretical model has been developed in this paper by calculating...

... for part forming or molding. Since this method is being developed for commercial use, there is a need to be able to predict the response of PEL tools to both structural and thermal loads encountered during a manufacturing process. In this paper, a general approach for structural modeling of PEL tools...

... tool for predicting residual stresses in ground parts. Thus developing a robust grinding process while minimizing residual stress is a lengthy trial and error process. This report proposes an analytic model, based on the temperature profile in the workpiece, for predicting the severity of the residual...
