对单件或小批量生产的零件,能否广泛采用位移度标注,关键在于解决计量问题。《航空标准化》今年第1期刊登了余道良同志的文章,提出用图解法确定位移度误差,我们认为这种方法是可行的。对于指定了基准的情况,这种方法是完全适用的。但对未指定基准的情况,还有待进一步的讨论。因为按孔的实际位置“找正”所建立的测量基准与孔组的理想位置是很难重合的,或者说,测量基准的选取不符
For single or small batch production of parts, the displacement can be widely used markings, the key is to solve the measurement problem. In the first issue of this year, “Aviation Standardization” published an article by Comrade Yu Dao-liang, proposing the use of graphic method to determine the displacement error. We think this method is feasible. This method is perfectly suitable for assigning benchmarks. However, no reference to the situation, pending further discussion. Because the actual position according to the hole “find” the establishment of the measurement standards and the ideal location of the hole group is difficult to coincide, or that the selection of measurement criteria does not match
