碩士 === 朝陽科技大學 === 工業工程與管理系碩士班 === 91 === This research offers a method to recognize the cutting features and then generate scheduling-ready machining feature removal sequences for the process planer. The method is designed to generate flexible and efficient routings for those parts with multiple interpretations. The research method is constituted with five major steps: Step 1: Calculate the removal volume of the work piece. Step 2: Find out the removal volume’s open surface, then divide, reconstruct and the volumes. Step 3: Reorganize the volumes according to its topology by comparing with the feature characteristics in feature bank. Step 4: List all logical sequences for volume removal. Step 5: Sift the feasible removal sequences out of the logical sequences, according to criteria such as minimal machine change, minimal tool change, and so on. Two example mill/turn parts are used to demonstrate the proposed method. All graphical and programming algorithms are implemented using ACIS solid modeler with ACIS GUI / API interfaces and Visual C++ programming. A discussion on the extension of the methodology is also provided.
