As a result of this research, a total machining system has been developed that automatically performs the planning of a cutting sequence, cutter selection and generation of cutting data, including generation of the cutter path based on the product model. The automatic machining data generation system receives the product description from the product design stage, extracts machining features, selects the tools to be used, plans the cutting order, and generates cutting control data in the form of NC data. The system is smoothly connected with the CAD system, and by including a machining feature extraction process, it eliminates the requirement of a human operator. In this research emphasis is placed on the discussion of milling feature extraction and tool selection processes for milling of pockets using the product description and machining knowledge. Here, milling feature means the volume machined by a single tool. The system proceeds deriving milling areas by means of cross sections and attributes based on product description, listing of candidates of tools used corresponding to each milling area, calculating milled areas using the tool centre path determination, and grouping milled areas according to tool diameters. Each group corresponds to one milling feature. Toools that are used for rough cutting, intermediate cutting and finish cutting are selected based on groups of milled areas. In these derivations, machining knowledge about cutters and know-how rules are used effectively. The developed system has been applied to the automatic milling data generation of the cavity for a mold with a complicated geometric shape. The milling process was executed using NC data generated by the system. Finally, the effectiveness of the system was certified.

作为这项研究的结果，一个总的加工系统已经开发，自动执行规划的切割序列，刀具选择和生成的切割数据，包括生成的刀具路径的基础上的产品模型。自动加工数据生成系统从产品设计阶段接收产品描述，提取加工特征，选择要使用的刀具，计划切削顺序，并以NC数据的形式生成切削控制数据。该系统与CAD系统平滑连接，并且通过包括加工特征提取过程，消除了对人工操作员的要求。本研究以产品描述与加工知识为基础，探讨型腔铣削加工之铣削特征提取与刀具选择过程。这里，铣削特征是指由单个刀具加工的体积。该系统继续通过基于产品描述的横截面和属性导出铣削区域，列出对应于每个铣削区域的所使用的刀具的候选，使用刀具中心路径确定来计算铣削区域，以及根据刀具直径对铣削区域进行分组。每组对应一个铣削特征。用于粗切削、中切削和精切削的刀具是根据铣削区域组来选择的。在这些推导中，有效地利用了刀具的加工知识和专有技术规则。该系统已成功应用于复杂几何形状模具型腔铣削数据的自动生成。铣削加工是利用系统生成的数控数据进行的。最后验证了系统的有效性。
