Abstract

Burr is the main problem in precision blanking. Uncontrolled burr not only affects the geometrical precision of the blanked parts, it also ruins their assembly. In this study, a comprehensive review on burr formation and the parameters that become the source of its occurrence are discussed. The analysis was made on the most relevant literatures and categorized based on key words and the methodology used. Based on the analysis, it is found that die clearance is the most relevant parameters, which carried out experimentally. The paper also presented the current challenges facing by the manufacturer as well as researcher on burr problem and outlined some of the solutions suggested to overcome this problem. In addition, the authors raised the problem on measurement of the burr as the size of the component become smaller and level of precision is higher.

Keywords:
