Modeling of Deposition Height in the Uncontrolled Laser Aided Direct Metal Deposition Process

비 제어 상태의 레이저 직접 금속성형공정에서 적층높이의 모델링

Models of the deposition heights in the uncontrolled laser aided direct metal deposition process are constructed for the enhancement of the process integrity. Linear and non-linear statistical models as well as fuzzy model are utilized as the modeling methods. The predictability of the models are evaluated with the values of the sum of square error. The algorithm to use the models in the feedback controlled system is suggested to increase the deposition height accuracy within a layer.
