| 摘 要： | 提出在螺旋转子加工制造过程中,采用三次NURBS样条曲线插补替代通常的微直线段插补;建立了螺旋转子端面摆线段三次NURBS样条曲线方程.在Pro/E软件上比较了三次样条插补曲线和理论摆线之间的精度误差.最后通过在立式加工中心上比较了采用三次NURBS样条插补和采用微直线段插补的加工精度和加工效率,采用三次NURBS样条插补加工取得了理想的效果.

| Abstract: | In this paper,during the spiral rotor manufacturing process,the cubic NURBS spline curve interpolation replaces the usual micro-straight line interpolation;establishes the cubic NURBS spline curve equation of the helical rotor's end cycloid curve.It compares precision error between the cubic spline interpolation curve and the theoretical cycloid in the Pro/E software.Finally,comparing machining accuracy and machining efficiency by using the cubic NURBS spline interpolation and micro-straight line interpolat... |
