description | Multi-tasking machine tools that can deal with several kinds of machining methods including turning and 5-axis control milling are attracted to achieve highly efficient machining in recent years. However, the machining process is generally complicated and the preparatory time becomes longer because there are a lot of available machining methods and the operational parameters such as the tool posture. Therefore, a computer aided process planning (CAPP) system is indispensable to reduce the efforts for the preparation and to improve the efficiency of machining process on multi-tasking machine tools. For this purpose, this study aims to propose a novel features recognition method can be applied to process planning of 5-axis index milling that is a characteristic machining method for mechanical parts having complex shapes on multi-tasking machine tools. In this method, machining primitives are obtained by dividing the removal volume, and cylindrical machining primitives for turning are additionally obtained even when the target shape does not have a cylinder part. Then, available combinations of tool postures are prepared for each machining primitive depending on the directions in which the machining primitive can be machined. The tool postures during 5-axis index milling are determined by referring specific information such as the number of tool postures. The machining primitives are divided again in each determined tool posture to recognize machining features in order to remove unmachined volume. Thus, the proposed method could be easily applied to process planning of 5-axis index milling on 5-axis controlled machining centers. The results of case study confirm that process planning of 5-axis index milling on multitasking machine tools is effectively realized based on the proposed method. |
