AUTOMATIC PROCESS PLANNING SYSTEM FOR END-MILLING OPERATION REFLECTING CAM OPERATOR’S INTENTION

抄録

An automatic process planning system for end-milling operation is proposed, in which CAM operator's intention for process planning is considered. In the previous process planning systems, the machining sequence is calculated geometrically. However, it remains difficult to determine the best machining sequence from the large number candidates of the calculated machining sequences. The previous process planning systems also do not consider CAM operator's intention in the determination of the appropriate machining sequence. First, our new process planning system stores the priority of machining features to be machined and the geometrical properties of the selected machining region from operations of CAM operators to decide the machining sequence. After storing the priority of machining feature and the geometrical properties, the appropriate machining sequence can be automatically determined by reflecting these information. CAM operator's intention, which is involved implicitly in the stored geometrical properties of the machining region, can be applied to decide the appropriate machining sequence.
