【摘要】 复杂形状刀具结构上的复杂性导致了磨削加工的复杂性。利用圆锥球头立铣刀这一典型复杂形状刀具 ,对其圆锥部分和球头部分的刀刃曲线的连续性进行了分析 ,然后对刀刃结构和加工特性进行研究 ,再利用 Frenet标架来确定砂轮的摆放姿态 ,实现利用活动坐标系控制机床坐标的插补进给 ,并通过磨削实例验证更多还原

【Abstract】 WT5BZ]The complexity of complex shaped tools′ structure makes the tool grinding process difficult. Taking the “equal spiral angel cone ball end miller” as an example, the continuity of space curves in the cone and the ball, and the tools′ structure and machining characteristics are analysed and studied in detail. Using Frenet frame to locate the grindstone, the interpolation was implemented by using real coordinate to control machine tool. The result was tested in the grinding experiment. [WT5HZ]更多还原
