CAD modelling of fire safe valve body by reverse engineering

Abstract

Abstract The government of Indonesia has a regulation called local content to push the manufacturing industries in order to increase their competitiveness. In order to reach that goal, technology transfer has been done, but it is a long way to go and impractical. So, one way to go is by the understanding of the product that has to be made. Reverse engineering is a specific technique to use because of its practicality. As the name implied, reverse engineering is the inverse of engineering design because the starting point is the product itself instead of the idea. In this paper, the product used as a case is the body of the fire-safe valve. The final goal of the reverse of the body part of the valve is the idea behind it or called the design intent. However, it is going to be a long process, and as the first step that will be presented in this paper, the goal is to get its CAD model of the fire-safe valve body.
