为了实现在复杂非结构环境下对木薯叶4种主要病害的高精度检测,提出一种基于选择性注意力机制的木薯叶病害神经网络检测改进算法MAISNet(Multiattention IBN Squareplus neural network)。以V2-ResNet-101为基础网络,先使用多重注意力算法优化加权系数,调整特征通道的语义表达,在特征图中初步构建显著性特征;然后在残差单元之后采用实例批归一化方法来抑制特征表达中的协变量偏移,在特征图中构建出显著性语义特征,实现高质量语义特征表达;最后在残差分支中采用Squareplus激活函数替代ReLU激活函数,保持语义特征在负数域的数值分布,减少特征拟合过程中的截断误差。对比试验结果显示,经过上述改进后构建出的MAISNet-101神经网络,对4种常见木薯叶病害检测的平均准确率达到95.39%,明显优于目前主流算法EfficientNet-B5和RepVGG-B3g4等。网络提取特征的可视化分析结果表明,高质量木薯叶病害显著性语义特征,是提高木薯叶病害检测准确率的关键。所提出的MAISNet神经网络模型可以完成实际场景下木薯叶病害高精度检测。

通过整体PCBN刀具硬态切削淬硬钢58SiMn实验,研究了切削速度和进给量对切削力及表面粗糙度的影响。实验结果表明:切削力和表面粗糙度值都随进给量增加而增大;在较低切削速度时切削力随切削速度提高而减小,当切削速度达到一定程度时出现拐点,继续提高切削速度切削力逐渐增大。在实验条件下,切削速度低于569m/min时刀片以磨损为主;当速度为768m/min时,以崩刃为主。
