Abstract：Aiming at realizing the direct modelingon solid carbide cutting tools with complex surface structure，the three-dimensional modeling of solid carbide end mills was researched. Complex curves and surfaces contained in the solid carbide end mills were analyzed，models of solid carbide end mills were divided into five features，each feature had detailed mathematical equation based on the tool designing rules during the modeling，the key geometric parameters influencing the feature generation were extracted，and each feature correspond to a general mathematical model. At last，the parametric interface design and parametric system of solid carbide cutting tools

were built up by UG/Open secondary development tools. The results indicate that，the system completes the parametric direct modeling on solid carbide cutting tools with complex surfaces，saves the computing time of surface equation，improves the design and model efficiency of tools.
