随着旧表面光洁度国家标准的废除,国家标准局于1983年制定了三个表面粗糙度标准,即: (1)表面粗糙度——术语表面及其参数GB3505-83; (2)表面粗糙度——参数及其数值GB1031-83; (3)表面粗糙度——代(符)号及其注法GB131-83。它们将用来代替旧的表面光洁度标准,并已于1985年1月1日正式颁布执行。新的表面粗糙度标准在概念、评定方法、标注方法以及测量方法等等方面都有较大的改变,为使三个表面粗糙度标准能顺利地贯彻执行,同时也为了使广大教师、机械设计、工艺和检测人员对它有一个全面而概括的瞭解和认识,特撰文予以介绍。
With the abolition of the national standard of the old surface finish, the National Bureau of Standards established three surface roughness standards in 1983, namely: (1) surface roughness - the term surface and its parameters GB3505-83; (2) surface roughness - Parameters and their values GB1031-83; (3) Surface roughness - generation (symbol) Number and its Note GB131-83. They will be used to replace the old surface finish standards and were officially enacted on January 1, 1985. The new surface roughness standards in the concept, assessment methods, marking methods and measurement methods, etc. have a greater change, in order to make the three surface roughness standards can be successfully implemented, but also to enable the majority of teachers, mechanical design , Craft and testing staff to have a comprehensive and general understanding and understanding of it, special articles to be introduced.
