摘要
研究曲率半径和割缝方式（直线和圆周）对无缝钢管激光割缝宽度的影响。发现：①在相同激光割缝工艺参数条件下，采用直线割缝方式的割缝宽度较采用圆周割缝方式的割缝宽度宽，且相同速度条件下，曲率半径愈小，二者的差值愈大；②无论采用何种割缝方式，曲率半径愈小的割缝宽度愈大。散热方式不同和曲率效应是造成上述现象的主要原因。最后提出了管材激光割缝时槽宽尺寸精度控制的补偿原则。
The effect of curvature radius and grooving patterns (line & circle) on the top kerf width of laser grooving for seamless pipe was investigated experimentally. Experiments showed two main conclusions: ① the top kerf width of laser grooving with linear grooving is bigger than that with circular grooving and their differential value increases with decreasing curvature radius,② no matter which patterns, the smaller curvature radius, the bigger top kerf width. The main reasons are the direction of different dissipated heat and curvature effect. At last, the authors give a compensation principle for dimensional accuracy control of grooving kerf width with laser beam for seamless pipe.
