技术表面的性能可以根据其特定的使用领域通过定制的特性来优化。这些高性能表面是板材-体积金属成形（SBMF）新技术所需要的，SBMF是板材和体积成形操作的组合。由于体积成形操作的高表面载荷，工具表面需要能够承受高应力状态。除了高耐磨性之外，这些表面的摩擦系数是板材材料流动的重要标准。表面特性可以通过使用高进给和微铣削工艺等技术进行调整，从而产生不同的摩擦系数，优化刀具的功能性能。根据这些不同的制造工艺，不同的残余应力被引入成形工具的表面下。研究了高进给铣削和微铣削加工微结构表面残余应力X射线衍射测量的可靠性。
Abstract The performance of technological surfaces can be optimized via tailored characteristics according to their specific field of usage. These high performance surfaces are needed for the new technology of Sheet-Bulk Metal Forming (SBMF), which is a combination of sheet metal and bulk forming operations. Due to the high surface loads of bulk forming operations, tool surfaces need to be capable to withstand high stress states. Additional to a high wear resistance, the friction coefficient of these surfaces is an important criterion for the material flow of the sheet material. Surface characteristics can be adjusted by using technologies such as high-feed and micromilling processes resulting in different friction coefficients optimizing functional performance of the tools. In dependency of these different manufacturing processes, different residual stresses are induced into the subsurface of the forming tool. Reliability of residual stress measurements via X-ray diffractometry for microstructured surfaces produced through high-feed milling and micromilling is investigated.
