ABSTRACT

ABSTRACT

Sculptured surfaces are widely used in aeronautical, automotive, electronics, and other manufacturing industries. Three-axis computer numerically controlled (CNC) mills are commonly used to mill these surfaces and their respective mold and die tooling. Research on tool path planning for sculptured surfaces using end-mills for 3-axis CNC milling have focused on five methods of tool path generation: isoparametric, surface-plane intersection, isocusp, steepest directed tree, and steepest directed isocusp (SDIC) method.

The purpose of this thesis is to examine and quantify the benefits of using the SDIC tool path generation method for a series of basic primitive shapes as well as freeform concave and convex surfaces. These basic primitive shapes are chosen to show the effect of angle of inclination and steepest path placement on SDIC tool path length.

An algorithm is presented which generates the SDIC tool path for general convex and concave sculptured surfaces. The results of the SDIC method are presented and compared with conventional tool path generation methods for these surfaces.
