In order to protect the products and tools from wear during forming processes, mineral and synthetic lubricants are used. Forming lubricants minimize friction as well as wear and remove abrasion and heat from the forming zone. Thus, the application of lubricants is useful, however after the forming process, the conventional forming lubricants need to be removed from the formed part to provide a clean surface for subsequent manufacturing and coating operations. Therefore, the goal of this research is to prove the suitability of water as a replacement for conventional forming lubricants. Due to the low viscosity of water, it cannot be used under conventional conditions. The tool surface must be structured in such a way that it is hydrophobic to be able to retain water in the high load forming region. Moreover, a proper forming speed must be identified whereby the friction can be minimized during the forming process with water. These methods are examined separately and then applied on a deep drawing process. After the forming process, the tools are analyzed by the means of wear and compared to conventional processes to demonstrate the potential of the forming process with water.

为了保护产品和工具在成型过程中免受磨损，使用矿物和合成润滑剂。成型润滑剂可最大限度地减少摩擦和磨损，并消除成型区域的磨损和热量。因此，施加润滑剂是有用的，但是在成形过程之后，需要从成形部件中去除传统的成形润滑剂，以为后续的制造和涂覆操作提供清洁的表面。因此，本研究的目的是证明水作为传统成型润滑剂的替代品的适用性。由于水的粘度较低，不能在常规条件下使用。工具表面的结构必须具有疏水性，以便能够在高负载成型区域保留水分。此外，必须确定适当的成型速度，从而最大限度地减少与水成型过程中的摩擦。这些方法分别进行检查，然后应用于拉深工艺。成型过程结束后，通过磨损对工具进行分析，并与传统工艺进行比较，以证明水成型工艺的潜力。
