机械零件表面特征的数字化综合表达方法

在自动化机械制造中,一个关键技术是对机械零件表面质量的表达和实现.本文提出一种描述机械零件表面特征的综合参数法.它首先,从工件表面测量并获取表面特征数据,再将每组数据作线性变换及非量纲化;然后建立非量纲参数下的参考系;最后,确定零件表面特征的位置并给出综合参数表达表面特征.按本方法,零件表面的理想参数值来源于且只能来源于已知表面.该方法不仅可以有效地评价已加工表面质量,而且为机械产品的数值化网络化设计制造奠定技术基础.

Comprehensively Digital Descriptions of Mechanical Component Profile

One of the key techniques in automatic manufacturing is the proper representation of the surface layer quality of a component.Our current study presented a comprehensive parameter method to solve this problem.First,the characteristic data for the surface layer are collected,followed by the transform and non-dimension process.Then the characteristic point of a component surface is located within the non-dimensional system.Finally,the comprehensive representation is carried out.All the characteristic data use...
