| Outline of Final Research Achievements |
In this study, we developed a new efficient planning method of cutting condition and cutter location for continuous multi axis controlled machining. First, NC simulation algorithm for workpiece volume in machining process and an accurate simulation method for instantaneous cutting force are proposed. Then, automatic optimization system for cutter location and tool posture has been developed with the proposed simulation models.
In the optimization system, the tool posture on cutter location is gradually renewed by a new candidates of tool posture. These process are applied for each cutter location in continuous tool path in NC program. To shorten calculation time, the ultra-parallel processing technology is introduced. In the developed prototype system. The developed system can optimize NC program which is generated by commercial CAM system for aerospace parts, and maximum torque loaded on cutting tool on each cutter location can be reduced.
