一、形位公差的标注(一)被测要素的标注方法对被测要素的形位精度要求,采用细长实线的长方形框格代号标注。公差框格分成两格或多格,框格内从左到右,第一格填写公差项目,第二格填写公差数值,第三格和以后各格填写基准代号的字母。公差框格用指引线与被测要素相连,指引线的箭头指向公差带的宽度方向或直径。
First, the shape of the tolerances of the label (A) of the measured elements of the labeling method of the measured elements of the shape of the precision requirements, the use of slender solid line rectangular box marked code. Tolerance grid is divided into two or more grids, from left to right within the grid, the first grid to fill in the tolerance item, the second grid to fill in the tolerance value, the third grid and after the grid to fill in the letters of the reference code. Tolerances The grids are connected to the element under test with the lead and the arrow of the lead is directed to the width or diameter of the tolerance band.
