A Fragmentation Based Approach to the Free Form Surface Milling

Abstract

In this paper, authors performs analysis of the free-form surface milling based on the fragmentation of the design elements which create active surfaces in tool making. Their analysis is based on fragmentation approach which makes the most of combining CAD, modelling and testing objects in tool making as well as selecting of the fragments with parts of free-form surfaces. Examples being introduced in this paper point out that it is volume based fragmentation of free form surfaces which allows to associate CAD design of tooling parts, their modelling and producing in chosen scale as well as testing different milling strategies. Results also showed that it is the Lining strategy of ball end milling which denotes desired compromise between machining time and surface quality when ball end milling fragments with different signed curvature radii.
