闭式叶轮通道五轴数控粗加工刀具路径规划
Tool-path planning for 5-axis NC rough machining of closed impeller channel
摘要
Abstract
A new layered milling method ,using conical surface for layering the channel ,is presented for 5‐axis NC rough machining of centrifugal ventilator closed impeller channel .The conical surface is formed by rotating the straight line of blade on meridian plane around the impeller axis .T his layered method can make each processing region of conical section consist of four curves and have similar topology shape .Then ,the contour parallel tool path and the spiral tool path which are suitable for layered machining ,are described .This method is very suitable for rough machining of channel parts , and is also simple and efficient .关键词
