摘要

为实现激光非垂直切割高分子材料,建立了激光非垂直切割模型。通过求解阈值能量方程,得到切缝宽度和热影响区(HAZ)宽度随激光线能量、入射角和离焦量的变化规律。在CO2连续激光切割系统上,采用正交试验法,针对聚对苯二甲酸乙二醇酯(PET)薄膜材料进行切割试验,发现入射角在-57.3°~57.3°范围内、离焦量在-15~15 mm范围内时,切缝宽度和HAZ宽度变化平缓,切割质量良好。结果表明,模型能够很好地预测激光非垂直切割高分子材料时的切缝宽度和HAZ宽度,为激光切割复杂曲面膜片提供了参数指导。

Abstract

In order to realize non-vertical laser cutting of polymer materials, a non-vertical laser cutting model is established. The change laws of kerf width and heat affected zone (HAZ) width with the laser line energy, the incident angle and the defocusing amount are obtained by solving the threshold value energy equation. In the continuous CO2 laser cutting system, the cutting experiment is done on polyethylene terephthalate (PET) film with the orthogonal experimental method. It is found that the kerf width and the HAZ width change gently and the cutting quality is good when the incident angle is in the range of -57.3° to 57.3° and the defocusing amount is in the range of -15 mm to 15 mm. The results show that this model can accurately predict kerf width and HAZ width in non-vertical laser cutting of polymer materials, which provides parameter guidance in laser cutting of complex films with curved faces.
