个性化定制产品的3D模型是唯一的，为了加工每个模型，需要唯一的刀具路径。手动生成刀具路径对于这些产品的大规模生产在经济上是不可行的;一个可行的选择是自动生成刀具路径。刀具路径取决于刀具形状，而曲面优化加工的一个重要部分是刀具形状的选择。本文主要研究定制木牌大批量生产中最佳刀具形状的选择。球头和圆角端铣刀定位在沿定义的刀具路径轨迹沿着的给定点。比较这些刀具位置以确定哪个刀具实现最大的材料去除或表面粗糙度，即，扇形高度计算刀具在沿刀具路径沿着的所有点处的残留部分和去除的材料，并对其进行处理，以确定用于加工曲面的最佳刀具。结果表明，表面的几何形状有很大的影响，加工表面所需的工具的类型。
The 3D models of personalized custom products are unique, and to machine each model, a unique tool path is required. The manual generation of the tool paths is not economically viable for the mass production of these products; a viable option is to generate the tool path automatically. The tool paths depend on the tool shape, and an essential part of optimal machining of sculptured surfaces is the selection of the cutter shape. This paper focuses on optimal tool shape selection for the mass production of custom wooden signs. Ball nose and radiused end milling cutters are positioned at a given point along a defined tool path footprint. These tool positions are compared to determine which cutter achieves maximum material removal or surface roughness, i.e., scallop height. The scallops and the material removed are calculated for the cutter at all points along the tool path and are processed in order to determine the best tool or tools for machining the surface. Results show that the surface geometry has a great impact on the type of tool required to machine a surface.
