With the development of machine manufacture science and technology toward precise, quality evaluation of precision parts has put forward higher request. Problems are pointed out in this paper based on comparison and analysis of burr standard at home and abroad. This study suggests the viewpoint of edge quality of precision parts and provides the fundamentals for enhancing edge (burr) quality according to items such as economic cost, technology level, manufacture level, personnel technological capability and production management level. These have important theoretical value and applied prospects for further enriching and perfecting burr standard, promoting precision machining and automatic machining technology. |
