| Abstract: | 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. |

| Keywords: | laser cutting spot radius compensation laser optical axis vector |
