The NC machining of blends in large quantities of parts with complicated mold surfaces is always a difficult job. Currently, spherical cutters are usually used in such cases by reciprocating movement in the transverse direction. According to the features of blends, a new way to machine arc shaped blends of equal radii with forming cutters in the longitudinal direction is proposed. The method of constructing a rolling ball for the blends and some basic concepts are described and the method of calculating the keel line and the critical line of the blends are derived. Algorithms for determining the tool path in the longitudinal direction for both convex and concave blends are given. The interference occurring in the machining of convex ones with forming cutters is discussed. In accordance with different principles of interference occurrence, the interfrence is divided into two categories, the arc length interference in the transverse direction and the curvature interference in the longitudinal direction. Measures to avoid such interference are suggested.
