| 摘 要： | 在数控激光切割加工中，由于作为刀具的激光焦点具有一定的半径，因而刀具中心轨迹并非零件实际轮廓，存在一个刀具半径补偿问题。为此提出了激光切割B样条曲线的一种刀具半径补偿方法。该方法利用常规等距曲线的数学模型及B样条曲线的端点性质，通过主动调整控制参数，获得精确的保形的等距曲线。其交点采用数值迭代求解，算法过程简单。

| Abstract: | In computer numerical control(CNC) laser machining, because laser focus has radius,track of cutter is not practice contours of part,problem of cutter radius compensation is in existence. A method about B spline curves cutter radius compensation is presented.It makes use of traditional mathematical model and character of end point of B splines, regulates controlling parameter,so produces accurate B spline offse curves.The intersection point of B spline offset curves is solved by numerical iteration method |
