Especially in forming processes such as deep drawing, a reduced use of lubricants can be highly promising in saving resources and reducing production costs. Ultimately, the highest savings can be realized by a complete lubricant free deep drawing process - namely dry forming. In this paper, an approach for lubricant-free forming by means of a protective coating and micro-structuring of the tool is presented. The work focuses mainly on the tool optimization to improve its frictional and wear properties. It is shown that ta-C coated tools can reduce friction up to 15% compared to the lubricated case. Moreover, it is outlined that a micro-structuring of the tool by Direct Laser Interference Patterning technology can reduce the tool wear.endeep drawingdry formingta-C coatingdirect laser interference patterning621671conference paper
