Abstract Scope |
An approach of using volatile media (CO2) as a lubricant for the dry metal forming process has been integrated with additively manufactured (AMed) dies. The performance of volatile media to reduce friction and improve product quality is confirmed in the pull-out tests. Note that the evaporation of CO2 leaves no residue, which is conducive to environmental protection. In the pull-out test, the liquid CO2 is supplied through AMed dies with microholes in the dies and sprayed into the contact zone between the dies and sheet to function as a lubricant. The result shows that CO2 pressure and microhole geometry have a significant effect on friction performance. |
