| 摘 要： | 基于“最短距离线对”(SDCP)刀位误差分布计算原理,提出了一种利用圆环面刀具来进行叶片过渡区域的宽行加工的刀位优化数学模型.以圆环面刀具的环心圆前沿上的各点到被加工曲面等距面的误差在控制范围内,后沿上的各点到被加工曲面等距面的误差大于零,以及环心圆上的各点到相邻曲面等距面的误差大于零作为刀位计算的约束条件,以行宽作为...

| Abstract: | Based on the shortest-distance-curve-pair(SDCP) cutting error distribution calculation model,a new 5-axis clean-up machining algorithm for blade's root area machining with torus tool is proposed.In order to avoid interference,several constraints are established,which are to limit the error between each discrete point on the front edge of the centre circle of the torus tool and the offset surface of the workpiece to the control range,to enable the error between each discrete point on the back edge of the cen... |
