With the increase in machine tool types, including multi-axis control and multi-function machine tools, it can be difficult to select the appropriate machine tools for targeted parts machining. This study aims to automate machine tool selection by evaluating and comparing machining processes on a variety of machine tools. A system to analyze machining process based on the functional description of machine tools is developed as a first step. In the system, supposed machine tool structures are represented first corresponding to their form-shaping motions. Then, machining features are recognized using both CAD models of the workpiece and target shapes. The machining process consisting of a number of machining operations is analyzed using specific notations, and the operation expression matching the axis configuration is assigned to each recognized machining feature to decide the feasible machining operation. An enumerated machining operations list in the order of machining sequence is finally obtained as the machining process according to the machine tool structure. From a conducted case study, it is confirmed that the machining process analysis results could successfully support machine tool selection.

随着包括多轴控制和多功能机床在内的机床类型的增加，可能难以为目标零件加工选择合适的机床。本研究旨在通过评估和比较各种机床上的加工过程来自动选择机床。第一步，开发了一种基于机床功能描述的加工过程分析系统。在该系统中，首先根据假定的机床结构的形状运动来表示它们。然后，使用工件和目标形状的CAD模型识别加工特征。使用特定的符号来分析由许多加工操作组成的加工过程，然后，将与轴配置相匹配的运算表达式分配给每个识别的加工特征，以决定可行的加工操作。最后，根据机床的结构，获得了按加工顺序排序的加工清单，作为加工过程。通过进行的案例研究，可以确认加工过程分析结果可以成功地支持机床的选择。
