고속상륙정 LSF-2의 시뮬레이터 조종간의 역설계와SLA방식 적층제조의 치수특성

Abstract

Reverse engineering in mechanical design is a method that infers the dimensions of mechanical parts in reversethrough measurement and is used when design drawings are not available or the restoration of damaged or wornparts is required. In addition, it is applied to the design and production of new product models from existing ones,thereby reducing the product development period and cost. Recently, as computer performance has improved, reverseengineering using three-dimensional (3D) scans and digital manufacturing using 3D printers have become common. In particular, handheld 3D scanners are widely used to measure the dimensions of mechanical parts because theyare easy to move, can be used anywhere, and can measure the dimensions of shapes, such as nonlinear curvedsurfaces. In this study, dimension measurement and reverse engineering were performed with a handheld 3D scannerusing the light combination method. A prototype of the control rod of the LSF-II simulator, which is a high-speedlanding craft, was manufactured using an SLA-type 3D printer, and its dimensional characteristics were analyzed.
