New Approaches to Determining Shortest Cutters and Work Piece Setups without Over-travel for 5-axis CNC Machining

摘要: Five axis CNC machining centers are widely used in the industries for producing complex parts. Due to two more axes as compared three machining, it provides efficient and flexible way of machining. Besides this flexibility, accidental collision possibilities between cutting system other moving parts machine tools also increased. These collisions could be avoided by changing orientations tool during path planning or adjusting cutter length holder size after generation part coordinate system. Collision detection removal optimum depends on configuration five tools. No. possible candidates may vary with Since fully utilization existing facilities industry is high demand, therefore, selecting one critical parameter length, maximum work space 5-axis another task. This dissertation comprises main works. In first research work, a comprehensive approach determination specific developed. The complete (the tool, spindle), process model fixture collision. represented point cloud data spindle regular shape truncated cone cylinder respectively. checking conducted steps. In step KD-tree structure employed method developed which confines searching local region second new mathematical points established. This has capability length. In kinematics table rotating tilting setup parameters mounting defined. A precise parameters, gives opportunity Many simulation software such vericut can simulate G-codes given verify over travel limits well machine. research, guarantee without translational axes. based predetermined strategies, means, already
