Blanking burr and punch wear are two phenomena closely linked. This leads to consider burr as the best criterion for regrinding or renewing blanking 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 punch wear. In order to reach this goal, a method for measuring the volume of burr has been developed. This method is based on the use of 3D topographical images. On the other hand, punch wear was calculated by combination of mathematical models describing the evolution of the geometric shape of the punch. This model links the variations of the geometry of the punch, depending on the number of press storks. The final aim of this study is to identify a relationship between burr and punch wear.
