1前言连杆大小头结合面的破口缺损(俗称“爆口”)是在制造过程中形成的。对爆口的探测是批量生产方式下对工件表面缺陷进行检测的一个典型例子。但在批量生产的汽车、摩托车、内燃机等行业,所采用的人工目测方法不但效率低、劳动强度大,且对标准中规定的定量评定要求无法准确执
1 Preface Connecting rod size head joint surface defect (commonly known as “pop”) is formed in the manufacturing process. The detection of bursts is a typical example of the detection of workpiece surface defects in mass production. However, in mass production of automobiles, motorcycles, internal combustion engines and other industries, the artificial visual method used is not only inefficient, labor-intensive, and quantitative evaluation of the provisions of the standard requirements can not be accurate
