Abstract

Abstract: CAD model quality in parametric design scripts largely determines the position of inflexibility and rigidity of a 3D model (how easy it's to alter the figure) as well as its reusability (the capability to use being figure in other surrounds and operations). In the environment of mechanical CAD systems, the nature of the point- grounded parametric modelling paradigm, which is grounded on parent – child interdependencies between features, allows a wide selection of approaches for creating a specific model. In this project involves designing and fabrication of the combination tool to perform desire operation. This combination tool can perform two operation which is End milling, Reaming, this can be done in such manner that the lower part that is end mill will remove the material from previously drilled hole then the second stage of operation commence in which the reamer will finish off the small tiny particle in order to achieve desired flawless finish. The use of the combined cutting tools to optimize the productivity of fabrication & operative time by reducing the time to change the tools. Design of the tool has been done with the assistance of some software which is Catia, Blender. Keywords: Combination tool, End milling, Reaming, Catia.
