The neural network is applied to predict the noise smoothing data as a main diagnostic tool to determine the optimal noise smoothing result. This method solves the problem of choice of neighborhood and iterations in general local projection method effectively. 该方法将神经网络的预测精确度作为评判噪声平滑效果的主要准则,有效地解决了常规局部投影方法中邻域半径、迭代次数等参数选取问题。
The active-lap is able to remove the middle and high frequency errors by smoothing, and the small tool is adapt for removal of the local error. 计算机数控能动盘光学加工技术具有高加工效率和抑制中高频能力,而小磨头光学加工技术则有很强的局部误差修正能力。
The rolling extruding process of smoothing holes on the checking cylinder of car is introduced, the process principle, the structure of rolling extruding tool, parameters and points of the rolling extruding technology are presented. 介绍了汽车制动缸孔的滚挤加工原理、滚挤工具结构、滚挤工艺参数及滚挤加工要点。
