几何形状误差 meaning in English

error in geometrical form

The 0 . 001mm dial indicators are a high accuracy length measuring tool . they are widely used for measuring the geometric deviation and position deviation of workpieces
千分表是一种高精度的长度测量工具，广泛用于测量工件几何形状误差及相互位置误差。
The dimensional globoidal indexing cam mechanism , as a result of the steady movement , accurate , the transmission ceaseless and is suitable for high speed indexing and precise indexing . now it is the most ideal high speed precision indexing mechanism in the world , and it is being widely applied on each kind of automaton and the production line , this mechanisms prospect of application is broad , arouses the people enormous interest . but the examination of the globoidal indexing cam mechanism is a quite weak link , the manufacturers don ’ t give the examination because of the difficulty of the geometry shape error examination of the cam contour
空间弧面分度凸轮机构,由于运动平稳、准确、传动无间隙而适用于高速分度和精密分度,是当今世界上最理想的高速精密分度机构,正被广泛应用于各种自动机和生产线上,该机构应用前景广阔,引起人们极大的兴趣,而弧面分度凸轮机构的检测是一个比较薄弱的环节,一般生产厂家由于凸轮轮廓几何形状误差检测困难而不予检测,因此本试验台的研制具有极其重要的意义。
