... 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...

...-dominated) material removal was studied and subsequently related to the threshold conditions for spatter formation. The model was subsequently optimized by examining the significance of the O 2 effects considered. The effect of the pressure induced on the melt surface when an assist gas jet is used during...

... for predicting instantaneous chip load, static and dynamic cutting forces, and tool deflection. Part 1 of this paper details the modeling methodology and demonstrates the capabilities of the simulation for machining a complex surface. Part 2 details both the model calibration procedure and discusses a case study...

...B. M. Imani, Ph.D. Candidate; M. A. Elbestawi, Professor, Fellow ASME In this paper, B-rep solid modeling techniques are used to deal with geometric modeling issues encountered in ball-end milling simulation. The precise B-rep model of the cutter swept volume is developed using advanced sweeping...

...Guangjun Zhang, Professor; Liqun Ma, Graduate Research Assistant The principle of structured light 3-D vision is introduced, and using projective and perspective transformations, the mathematical model of grid structured light based 3-D vision inspection is established in homogeneous coordinate...

... space defined by the zeros of a finite number of analytic functions are computed and are characterized as closed form equations of surface patches of this volume. The motion of a cutter tool is modeled as a surface undergoing a sweep operation along another geometric entity. A topological space...

...Alejandro Felix; Shreyes N. Melkote; Yoichi Matsumoto This paper addresses the modeling and prediction of the normal holding force in an electromagnetic chuck used in precision machining applications. Knowledge of the normal holding force is necessary to determine if a given chuck is capable...

...John T. Roth, Assistant Professor, Assoc. Mem. ASME,; Sudhakar M. Pandit, Professor, Fellow ASME, In the authors’ previous work, univariate models were fit to acceleration data to predict impending tool failure. Numerous end-milling life tests, conducted under a wide variety of cutting conditions...

...D. J. Weir, Graduate Student; M. J. Milroy, Graduate Student; C. Bradley, Associate Professor; G. W. Vickers, Professor The design of products containing sculptured surfaces typically begins with the crafting of a clay or wood model. The physical model must be reverse engineered to create a CAD...
