数字积分法渐开线插补原理

Digital Integration Interploting Principle for Involute

在分析圆的渐开线形成原理的基础上，建立了数字积分法渐开线插补原理。该插补原理建立过程要比圆弧插补复杂。发生线始终切于基圆，渐开线插补原理是采用先进行基圆的圆弧插补，由插补点确定发生线切点的位置，而后进行渐开线插补。

A digital integration interpolating principle is built on the basis of analysis made on circular involute forming principle. The building process of the in terpolating principle is more complicated than that of the circular interpolation. The generating line is always tangential to the basic circule. The principle is made,at first, the basic circule is interpolated and the positions of tangential points of the generating line are decided by the circular interpolating points, then the involute interpolation is made.
