Geometric Modeling for Five-axis CNC Machining of Mold Surface with Flat-end Tool

摘要

This paper taken the flat-end tool and machined surface as a pair of mutually conjugate space contact tooth envelope surface and used the Frenet frame of differential geometry to describe the NC machining tool path in five-axis CNC machining of mold surface with flat-end tool. Thus the geometric model in five-axis CNC machining of mold surface with flat-end tool was established.
