The development of adaptive modified appearance using operating window methods for optimizing electron beam

The purpose of this article is to address the applications of an operating window with a Taguchi-fuzzy logic design in conducting a reduced number of experiments to yield the optimal conditions and to develop robust melted bead properties of the electron beam (EB) process. The effects of parameters produced on a window on EB bead surface are studied, and dimensions of operating window using travel speed while adding different noise factors are identified. Using ANOVA, significant factors are identified and accounted for nearly 75% of the total variance. The defects can be reduced by widening an operating window. The experimental results show that, an extensive analysis of the quality of the results can be obtained with the successful optimization of functional characteristics. This new strategy allows one to design, simulate, and optimize a system, and accurately performs in a group of characteristics.
