摘　　要：提取方案是提取操作的关键内容之一。通过分析提取方案本身特点及其与产品结构特征和形位精度之间的内在规律,给出面向产品形位精度数字化设计与计量的提取方案应用方法。并以圆柱度误差为例,说明该方法的应用规律及其工程实践意义。Extraction sc extraction schemes for digital heme is one of the key contents of extraction. Present application method of design and metrology of product form and location precision by analyzing the interior characteristic of extraction scheme and its inherent regularity between extraction schemes and product structural characteristics and form and location precision. Moreover, illuminate the application law of this method and its meaning in engineering practicability by taking cylindricity as example.
