摘要

磨牙具有牙尖、牙脊、牙窝等复杂的特征，其修复体的CAD模型通常采用STL格式。本文拟在STL的基础上，引入一种新的拓扑结构，提出基于顶点的实体偏移算法，实现磨牙义齿粗/精加工刀具轨迹的快速生成。仿真加工表明，该算法稳定性好，计算速度快，加工精度高。这将积极促进口腔修复CAD/CAM软件的临床应用。

Research on the Algorithm of Tool Path Rapid Generation for NC Machining of Molar Prosthesis

Molar bears complicated features like cusp, ridge and fossa etc, and the CAD model of its prosthesis usually comes in STL format. On the basis of STL, this paper intends to introduce a new topological structure, and will propose the vertex-based entity offset algorithm in order to realize the rapid generation of roughing/finishing tool path for molar prosthesis. Indicated by simulated machining, the proposed algorithm proves excellent stabilization, fast calculation speed and high machining accuracy. This will positively accelerate the clinical application of demotic dental prosthesis CAD/CAM software.
