摘要
分析了三维激光切割光斑半径补偿的原理,提出了一种基于激光光轴矢量的激光光斑半径补偿算法。对空间平面曲线依据平面光斑半径补偿原理进行补偿计算,对空间直线提出了基于激光光轴矢量的4种过渡方式及补偿原则,建立了准确的激光光斑补偿模型。
Laser spot radius offset principle for the 3D laser cutting is analysed,and a kind of algorithm based on laser optical axis rector is proposed. The space planar curve is calculated by planer laser spot offset principle,and for space location relationship between the line and line,four transition way and compensation principle are propoesd,thus accurate laser spot compensation model is established.
