The increasing use of additive manufacturing technologies goes in hand with an increasing demand of a flexible and efficient finishing process that meets the emerging challenges. For most mass finishing processes, high roughness values of additive manufactured workpieces lead to tremendous processing times. High-energy mass finishing processes such as centrifugal disc finishing have the potential of finishing additive manufactured workpieces efficiently. However, fundamental research on centrifugal disc finishing of additive manufactured workpieces is strongly limited up to now. For this reason process design for centrifugal disc finishing strongly relies on the experience of trained workers and optimisation is done by trial-and-error approaches, both resulting in high costs. Main goal of the research project is a fundamental analysis of the material removal mechanisms and a systematic build-up of knowledge on finishing of additive manufactured workpieces. This includes effects of the process parameters and media type on processing results in terms of roughness and edge rounding. A combined approach of empirical studies and simulated contact intensities is used.

随着添加剂制造技术的使用越来越多，人们对灵活高效的精加工工艺的需求也在不断增长，以满足新出现的挑战。对于大多数大批量精加工工艺，添加剂加工的高粗糙度会导致很长的加工时间。高能质量抛光工艺，如离心盘抛光，有可能有效地抛光添加剂加工的零件。然而，到目前为止，对添加剂加工零件的离心盘光整加工的基础研究还非常有限。出于这个原因，离心盘精加工的工艺设计强烈依赖训练有素的工人的经验，优化是通过反复试验的方法完成的，这两种方法都会导致高成本。该研究项目的主要目标是对材料去除机理进行基本分析，并系统地积累关于添加剂制造的零件的精加工知识。这包括工艺参数和介质类型对加工结果的影响，包括粗糙度和边缘圆整。采用了经验研究和模拟接触强度相结合的方法。
