| This is the sub-subject"The modern cutters on large and complex part are series manufactured and researched"of Heilongjiang province great science and technology tackle key problem item, which is mainly about the study of face milling cutter cut-in type.This paper described the moving contact theory of the 3D complex groove wave-edge milling insert. The mathematical model of nine kinds of cut-in style discriminant for the 3D complex groove wave-edge milling insert is deduced. The excellent mathematical model of the cumulate function of impacting disrepair life is founded on various cut-in styles.Based on mathematical analysis and simulation experiment, the front face equation, the front face moving equation, the cut-in contact equation, the join line equation and the shape of cutting field equation for 3D complex groove wave-edge milling insert are deduced. The changing quantityδof contact angle of the front face is imported. The nine new kinds of contact forms of the 3D complex groove wave-edge milling insert are put forward. Thereafter, the mathematical model of the nine kinds of cut-in style discriminant for the 3D complex groove wave-edge milling insert is established. The contact theory of 3D complex groove wave-edge milling insert is formed.The mathematical model of the cumulate function of impacting disrepair life is founded on various cut-in styles. That conclusion of the cumulate function of impacting disrepair life obey to the function of Weibull is reached. The cut-in style of the 3D complex groove wave-edge milling insert is chosen for best. The excellent cut-in style is the U style, and the V style, T style and S style are followed in order.Based on the theory of cut-in disrepair, two types of 3D complex groove milling insert are designed and developed. It provides a basis for milling cutter reconstruction. All the productions above are the theory foundation for further developing the 3D complex groove milling inserts.
