Forming of new sheet metals – Influence of tool roughness
This study, conducted at the request of Cetim’s “Sheet metal forming” Profession, is intended to assess the performance of the various tool material configurations for high-resistance sheet metal blanking operations.
The results obtained reveal that, in certain test conditions, a roughness of the punch with an Ra = 0.4 µm seems adequate to ensure the blanking of high-resistance sheet metals, in the case of rugged tool.
