Metrology of the burr amount - correlation with blanking operation parameters (blanked material – wear of the punch)
Source abstract
Abstract
Blanking burr and punch wear are two phenomena closely linked. This leads to consider burr as the best criterion for regrinding or renewing tools. Thus, in order to control the quality and cost in blanking process, it is necessary to measure with the best accuracy the amount of burr and wear punch. To do this, a method for measuring the volume of burr was developed. This method is based on the use of 3D topographical images. On the other hand, punch wear was calculated by combination of a mathematical model to the geometric shape of punch. This model gives the geometry variations of the punch, depending on the number of press storks. At the end, the aim of this study is to identify a relationship between burr and punch wear
