Abstract:

Molar crown is not only very small and thin-wall, but also has complex profile, especially occlusal surface that distributes many cusps, ridges and fossas is obviously different. If conventional processing method is used, it is impossible to rapidly and exactly machine molar prosthesis. To enhance machining velocity and improve surface precision of molar crown, an algorithm of entity rapid offset based on STL format is put forward. Applying Zigzag tool path planning and micro-machining cutter, finishing tool path for high speed milling molar prosthesis is generated. In terms of Mikron UCP800 high-speed machine center, molar all-crown whose material is Zirconia is successfully machined. Through test results show that the algorithm of tool path generation works fast, and amount of tool paths is rather few, moreover cutter feeds placidly.
