摘　　要：生成包络体,是数控加工仿真和验证、机器人路径规划等过程中的一个重要步骤。针对凸包的STL模型,提出了一种基于最大边界轮廓搜索的包络体生成算法,克服了现有算法复杂、计算效率低和通用性差等缺点,并以其在数控切削仿真中的应用实例,验证了算法的可行性。Generating enveloping solid is an important step in the process of NC cutting simulation or robot path planning. In this paper, an algorithm for generating enveloping solid is developed, which is based on searching the maximum boundary of the original solid and only suitable for the convex STL model. Compared with the existing algorithms for generating enveloping solid, this algorithm has more advantages in its simplicity, efficiency and versatility. It has been proved feasible by its application in the NC cutting simulation.
