特殊分段的精度控制方法探讨

在明确了分段精度控制意义及概念的前提下,对分段精度控制计划和精度控制管理过程作了详细分析,并制定相应的控制方法。首先针对舵臂分段,根据其尾部曲率较大以及不规则性,依据挂舵垂直性控制其精度;然后针对尾轴分段,根据同心度和尾轴管的定位控制该分段的精度;再针对主基座分段,主要根据基座面板水平度来控制该分段的精度;最后总结出典型分段精度控制方法。

On precision control of special segment

After clarifying the significance and concept of the segment precision control, this paper analyzes the control plan and management process, and formulates the corresponding control method. First of all, the accuracy of the rudder arm segment is controlled according to the larger curvature and irregularity of the rudder tail and the rudder verticality. Then, the accuracy of the stern shaft segment is controlled according to the concentricity and the position of the stern tube. Finally, the accuracy of the main base segment is controlled by the horizontality of the base panel. The precision control methods for special segments are summarized afterwards.
