| 摘 要： | 针对现代机械加工中广泛使用的复杂回转刀具,如模具铣刀、旋转锉、球形滚刀等,提出了任意回转面上的点和线的广义螺旋运动概念,并运用这一概念分别建立了复杂回转刀具广义螺旋线模型和广义螺旋面模型。该模型适用于任意回转刀具,克服了传统的螺旋运动概念和螺旋线、螺旋面理论只是针对圆柱形回转刀具的缺点。最后以球头刀具前刀面几何建模为例说明广义螺旋运动概念和复杂回转刀具几何建模方法的具体应用。

| Abstract: | The conventional concept of helical movement and theory of helix/helicoidal are no more applied to revolving cutters with arbitrary configuration. A generalized helical movement concept has been presented with respect to widely used complicated shape revolving cutting tools, such as mould mills, revolving files and spherical hob. With this concept, a generalized helix model and a generalized helicoidal model of complicated shape revolving cutters are formulated, which are unified to all sorts of revolving cutters. An example is presented to explain how the concept and modeling method are applied. |
