新的表面粗糙度标准已在各工矿企业中实施,工人同志对其各项内容还比较陌生,而对旧的表面光洁度却比较熟悉,希望有一个简单易记的关系式,把新旧标准的具体数值联系起来,便于看图、制图。下面把新的表面粗糙度中的轮廓算术平均偏差值 R_α、轮廓微观不平度十点高度值 R_z,同旧的表面 The new surface roughness standards have been implemented in various industrial and mining enterprises. The workers’ comrades are still rather unfamiliar with their contents and are familiar with the old surface finishes. They hope that there will be a simple and easy-to-remember formula that ties together the specifics of old and new standards Numerical connection, easy to see the map, drawing. The following new surface roughness in the arithmetic mean deviation R_α contour micro unevenness ten height value R_z, the same surface with the old
