Oberflächenabweichung (Femenino)

Description: A surface deviation on engineering surfaces is the deviation of a surface from its nominal shape. There are six surface deviation classes. Class 1 indicates the error of form and class 2 the waviness. Classes 3 to 6 relate to roughness - classes 3 and 4 to the surface roughness caused by grooves, score marks, bumps and scale, and classes 5 and 6 to the material's structural composition and lattice structure respectively. If several types of deviation are present at the same time, this is referred to as superposition. Various methods are used to measure surface deviations. A cross-section perpendicular to the surface is one very popular option. Errors of form are measured over the entire functional surface, while waviness and roughness can also be checked over parts of the surface.

Description: 工程表面上的表面偏差是指表面和其规定形状之间的偏差。 有六个表面偏差等级。等级 1 表示形状误差。等级 2 表示波纹度误差。等级 3-6 与粗糙度有关-等级 3 和 4 表示沟槽、划痕、隆起和剥落，等级 5 和 6 则分别与材料的结构组成和晶格结构有关。如果多个偏差类型同时出现，则称之为叠加式偏差。 许多方法可以用来测量表面偏差。常常使用垂直于表面的横截面来测量。在整个功能表面测量形状误差，同时，也可以在零件的表面检查波纹度和粗糙度。
