A new iso-scallop height tool path planning method in three-dimensional space

This paper presents a new approach for designing the tool paths in the machining of sculptured surfaces for computer numerical controlled end milling.In the proposed method,the tool paths are determined so that the scallop height formed by two adjacent machining paths is maintained constant across the machined surface.Unlike previous work on iso-scallop height milling,the present work considers the true 3D configuration of the milling procedure and can be used to generate better results,which is shown by examples.
