基于控制线的开式整体叶盘环形刀四轴加工算法研究

Algorithm Research on the Four-Axis Circular Cutter Machining of Open Blisk Based on the Control Curve

针对开式整体叶盘控制线球头刀四轴加工中,刀具易磨损、加工中需要多次换刀的问题,提出一种基于控制线的开式整体叶盘环形刀四轴加工算法。试验表明,该方法在现有球头刀控制线的条件下,简化了环形刀控制线生成的复杂性,并且解决了因球头刀加工刀具易磨损所造成的加工缺陷等问题。

During the 4-axis ball-end cutter machining of the open blisk based on the control curve, the cutter gets worn easily and the cutter must be changed for multiple times. Therefore, this research proposes a 4-axis circular cutter machining algorithm of open blisk based on the control curve. The experiment shows that the proposed method simplifies the complexity of generating the control curve of circular cutter under the current condition of the ball-end cutter control curve. Moreover, the method solves other problems including machining deficiency caused by the quick-wearing ball-end cutter.
