Laminated object manufacturing (LOM) is a rapid prototyping (RP) technology which can rapidly fabricate 3D physical model using layered manufacturing (LM) process. Hence, the RP such as LOM has been widely applied in manufacturing fields. However, the surface of the RP processed part is excessively rough to use industrial purpose due to the LM process itself. In order to improve the surface quality, additional post-machining such as coating and grinding process is required. These machining, however, are also detrimental to the original geometry of the part and is time consuming. In this paper, an intelligent methodology is proposed to minimize the machining area (PMA). An expression of the distribution of surface roughness is presented and the PMA is defined as an objective. Also, a genetic algorithm is applied to obtain reliable solution for complicated 3D CAD models which represent general industrial part. By implementing several applications, validity of the proposed methodology is demonstrated.
