摘　　要：通过对加工误差理论的分析,提出一种针对薄壁环形零件的精加工工艺,将装夹的定位点设定在薄壁环形零件的轴向上,以规避径向受力.同时延伸数码相机的视频功能,将粗糙度显微仪视场传送至电视屏幕,减少因个人视角造成的读数误差,提高测量精度.并将以上工艺与视频测量技术应用于教学实践中.Through theoretical analysis on manufacturing errors, a finish machining technology is initially proposed in terms of ring sheet parts. In this regard, the positioning points are fixed along axial direction to avoid radial loading. By using a digital camera, the images from a roughness microscope are transferred to a television screen. So far, this can reduce perspective reading error and improve measurement accuracy. To this end, the finish machining process and video measurement technology are applied for the educational purpose.
