摘要
推算了双圆弧拟合非圆曲线的数学模型,计算了在允许误差范围内节点表达式,编写了基于宏程序的双圆弧法拟合双曲线的节点计算程序和双曲线型零件加工程序,解决了在只有圆弧和直线插补的数控机床上加工非圆曲线型零件的问题。
This article calculates the mathematical model of fitting non-circular curve by double-arc method,computes node expressions within the allowable error range, compiles the node calculation program of double-arc method fitting hyperbola based on macro program and hyperbolic parts machining program, solves the problem of non-circular curve parts machining in CNC with only lines and circular interpolations.
