摘　　要：针对非线性曲线轮廓的插补,在数据采样插补的基础上,研究三次参数样条曲线恒线速插补方法,并通过构建OpenGL渲染环境,对数据进行仿真,完成了曲线恒线速插补的G代码设计,实现了复杂零件轮廓的插补。In order to realize nonlinear curve contour interpolation,how to achieve constant linear velocity interpolation was discussed for parametric cubic spline and OpenGL was used to do some data simulation based on data sampling interpolation,then G code of constant linear velocity interpolation was designed. Interpolation of outline of complex parts was completed.
