Additive manufacturing is a new approach to design and production. This applies in particular to processes such as repair and rework of selected components. Additive manufacturing can produce almost any shape, and from an MRO part perspective, additive manufacturing offers tremendous advantages. The special feature of additive manufacturing is that it is particularly economical for small-volume production as the number of units is irrelevant compared to the existing manufacturing process. The purpose of this study was started from the MRO point of view, and it Identify changes and respond to the Blisk It is a study on the effect of changing the conditions on the path of the toolpath and the CAM during additive manufacturing using CAM after finding suitable conditions. metal powder.The metal powder withstands various corrosive environments and age hardening occurs very slowly. Inconel 718, which can be used in various applications such as nuclear facility-related parts, aerospace, oil facilities, turbines, and valves, was used. This is SUS 316L with good high temperature strength. The variable of the laser used in the study is the laser power, and the variables on the CAM are Operation, Stepover, Pattern, etc. In the relation between laser power and feed, when feed is specified as 500mm/min, laser power of 700W was most suitable. As for the conditions on NX CAM, ADDITIVE PROFILE Stepover was 0.8mm for Operation, and Infills and Finish for Pattern. When stacking, each layer should be overlapped with the result. Therefore, the stepover should be smaller than the laser spot size and reprocessing should be done in terms of repair, so infills and finish were applied to work larger than the actual product shape.

The purpose of this study was to investigate the performance and quality of engine mounting member in repair parts of the accident vehicles by conducting mechanical and material properties experiments. The tests were conducted by the test equipments of chemical components analysis, radiographs and mechanical testing on the genuine parts and non-genuine parts of engine mounting member. Test results concluded; Tensile strength of genuine parts is about 270 N/㎟ but damaged non-genuine parts about 200 N/㎟. The chemical component of 12 components was similar genuine part to non-genuine parts but Ti, Ni component were appeared different. Non-genuine parts were 4 times in elongation, 2 times in hardness higher than genuine parts. We concluded that quality identification system of repair parts and circulation system establishment of repair parts market were needed.
