摘　　要：随着技术的发展,机器雕刻越来越多地用于包括橄榄核雕在内的手工艺品雕刻行业.为自动生成适合于橄榄核随形雕刻的三维模型,并快速生成雕刻刀具路径,提出了一种面向橄榄核机器雕刻的模型编辑和刀具路径规划方法.首先通过基于方向包围盒的刚性对齐、基于改进的径向基函数的网格变形和近似刚性网格变形将已有的三维模型进行编辑,得到适用于橄榄核随形雕刻的三维模型.继而将编辑后的模型切片,并根据预置的刀具信息快速生成四轴三联动刀路.实验表明,该方法能快速得到适用于橄榄核随形雕刻的网格模型和加工刀具路径,实际雕刻效果较好.With the development of technology, machine carving is increasingly used in the handicraft carving industry including olive-nut carving. We propose a method of model editing and tool path planning with automatic generation of 3D models suitable for shape-following olive-nut carving and rapid production of tool paths for olive-nut machine carving. We edit the existing 3D model and acquire a new 3D model suitable for shape-following olive-nut carving through rigid alignment based on the oriented bounding box, mesh deformation based on an improved radial basis function, and as-rigid-as-possible mesh deformation. Then, we slice the new mesh model and obtain the four-axis three-linkage tool path quickly generated according to the preset tool information. The experiments prove that the mesh models and tool paths suitable for shape-following olive-nut carving can be quickly obtained and favorable carving effects can be achieved by the proposed method.
