Toolholder

[TatianaResend]

There are no toolholders on the market specially built for SPIF processes. Therefore, the toolholder will be chosen from an existing one for another process and will be adapted to the specific needs of incremental sheet metal forming.

[TatianaResend]

Use an HSK type cone, which are for cutting tools with a cylindrical shank. Choose a cone that is tightened by a screw so that tool changes are simple. For this case, select the smallest cone.

• Chosen example: " HSK- A32 - Tool holder form B (WELDON)", for DIN 1835-B / DIN 6535 - HB https://sanchesblanes.com.br/produto/hsk-a32-porta-ferramentas-forma-b-weldon

Relevant information on the choice of toolholder can be found in Sónia Marabuto's thesis.

[TatianaResend]

The toolholder placed in the CAD was an internal diameter of 6, so it is preferable to change to the one with an internal diameter of 8.

[TatianaResend]

I changed the toolholder to diameter 8. Documentation for this task is missing.

[TatianaResend]

I already wrote it, but it remains to put the images in the documentation.
