The research within the transregional Collaborative Research Center SFB/TRR 136 “Process Signatures” focusses on a mechanism-based analysis of workpiece surface layer modifications caused by manufacturing processes. As a main hypothesis it is assumed that the internal material load, characterized by process independent physical and chemical quantities, is responsible for the resulting material modifications. This mechanism-based view on manufacturing processes is scientifically new. It is expected that the results of the research work will enable a knowledge-based selection of necessary manufacturing processes and the corresponding parameters for the targeted chemical and physical properties of the workpiece surface layer. For this purpose the Collaborative Research Center introduces the notation “Process Signatures” and aims at demonstrating its potential for a broad range of manufacturing processes.The objective is to identify functional relationships between observed workpiece material modifications and the internal material loads during the manufacturing process. The research in the first funding period has shown that setting up Process Signatures is possible by the chosen approach. For the second funding period it is planned to take into account the influence of the workpiece material state before the manufacturing process on Process Signature components. Therefore, the research work will focus on multiple subsequent internal material loadings, caused by one manufacturing process and caused in a process chain, and their effect on the resulting material modifications. In the third funding period Process Signatures shall be utilized to predictively manufacture targeted functional properties of a component in a predictive approach. It is expected that the Collaborative Research Center will significantly contribute to the solution of the inverse problem when designing manufacturing processes.

跨区域合作研究中心 SFB/TRR 136“工艺特征”的研究重点是对制造工艺引起的工件表面层变化进行基于机制的分析。作为一个主要假设，假设内部材料负载（以过程独立的物理和化学量为特征）是导致材料改性的原因。这种基于机制的制造过程观点在科学上是新颖的。预计研究工作的结果将能够基于知识选择必要的制造工艺和工件表面层目标化学和物理特性的相应参数。为此，协作研究中心引入了“工艺特征”这一概念，旨在展示其在广泛的制造工艺中的潜力。目标是确定制造过程中观察到的工件材料变化与内部材料负载之间的函数关系。第一个资助期的研究表明，通过所选方法可以设置流程签名。对于第二个资助期，计划考虑制造过程之前工件材料状态对 Process Signature 组件的影响。因此，研究工作将重点关注由一个制造工艺和工艺链中引起的多个后续内部材料负载，以及它们对最终材料改性的影响。在第三个资助期内，应利用流程签名以预测方法预测性地制造组件的目标功能属性。预计协作研究中心将为设计制造工艺时逆问题的解决做出重大贡献。
