这项工作的目的是相关的切削刃质量参数（响应），即：上切口，下切口，上切口的比率，下切口和切刃粗糙度的工艺参数，在这项研究中考虑，并找出最佳的切削条件。本研究所实施之制程因素为：雷射功率、切割速度及焦点位置。实验设计（DoE）通过实施Box-Behnken设计来实现在现有资源范围内更好的切割质量。建立了数学模型，建立了工艺参数和边缘质量参数之间的关系。此外，确定了工艺参数对每个响应的影响。然后，进行数值优化，以找出最佳的工艺设置，在该工艺设置下，质量特征处于其期望值。确定了各因素对响应的影响，并找到了最佳切割条件。（C）2010 Elsevier Ltd.保留所有权利。
The aim of this work is to relate the cutting edge quality parameters (responses) namely: upper kerf, lower kerf, ratio of the upper kerf to lower kerf and cut edge roughness to the process parameters considered in this research and to find out the optimal cutting conditions. The process factors implemented in this research are: laser power, cutting speed and focal point position. Design of experiment (DoE) was used by implementing Box-Behnken design to achieve better cut qualities within existing resources. Mathematical models were developed to establish the relationship between the process parameters and the edge quality parameters. Also, the effects of process parameters on each response were determine. Then, a numerical optimization was performed to find out the optimal process setting at which the quality features are at their desired values. The effect of each factor on the responses was established and the optimal cutting conditions were found. (C) 2010 Elsevier Ltd. All rights reserved.
