摘要

为推动激光技术在木材精密加工产业中的应用，研究以臭冷杉（

Abies nephrolepis

）为试验材料，运用方差分析探究激光切削参数（工作距离

、进给速度

和激光功率

）对切缝深度（简称缝深）与切缝宽度（简称缝宽）的影响规律，并构建数学模型预测切缝尺寸。采用三因素完全随机方差分析、交互效应检验及Tukey真实显著差异事后比较等方法对数据进行方差分析，以确定激光切削参数对切缝尺寸的影响以及切削参数间的交互作用显著性。结果显示，工作距离、进给速度和激光功率对缝深与缝宽均具有极显著主效应（

0.001）。按偏

²值排序，缝深的主效应大小为

，缝宽的主效应大小为

。二阶交互效应及三阶交互效应均达到显著水平，对缝深和缝宽的影响程度为：

；表明激光切削过程中存在明显的多参数耦合作用。依据建立的激光切削回归预测方程，发现工作距离与激光切削臭冷杉的切缝尺寸呈非线性关系，激光功率和进给速度与激光

切削臭冷杉的切缝尺寸呈线性关系。采用回归预测方程预测缝深的误差为21.30%，缝宽的误差24.94%。实际生产中可优先考虑固定工作距离。

Abstract

To promote the application of laser technology in the precision wood processing industry

this study investigated the effects of laser cutting parameters

including working distance (

)

feed rate (

)

and laser power (

)

on kerf depth and kerf width of

Abies nephrolepis

and established mathematical models to predict the kerf size. Multifactor completely randomized analysis of variance

interaction effect analysis

and Tukey's honestly significant difference

post

hoc

test were used to examine the significance of the main and interaction effects of laser cutting parameters on kerf size. The results showed that the cutting parameters

and

had extremely significant main effects on both kerf depth and kerf width (

0.001). According to partial

² values

the order of main effect size for kerf depth was

while that for kerf width was

. Both second-order and third-order interaction effects reached significant levels

and their influence on kerf depth and kerf width followed the order

indicating obvious multi-parameter coupling during laser cutting. Based on the established regression equations

the cutting parameter

showed a nonlinear regulatory effect on laser cutting of fir

whereas the cutting parameters

and

exhibited approximately linear effects. The prediction errors for cutting performance were about 21.30% for kerf depth

and 24.94% for kerf width

respectively. Therefore

the cutting parameter working distance

could be preferentially fixed in practical production to improve process stability.
