Optimized and accelerated process design and control in industrial Abrasive Flow Machining through numeric process models and better understanding of the process fundamentals

磨料流加工是一种加工形状复杂、内、外轮廓难以触及的零件的加工工艺。由于其固有的低材料去除率，磨料流加工仅用于表面质量改进、边缘圆化和去毛刺。磨料流加工通常是由磨料在被加工物体轮廓上的循环交替运动组成的。目前，磨料流加工的工艺设计是非常耗时和昂贵的，因为工艺的优化通常是在实验中迭代进行的。数字支持的工艺设计的潜力在以前的研究项目中得到了展示。要确定以往工业应用项目的成果，就必须进行知识转让。知识转让将在与合作伙伴罗伯特博世有限公司的合作下进行。为了更好地理解磨料流加工的基本原理，使数值模拟与实际更好地吻合，有必要对磨料流加工进行基础研究。在此背景下，本研究项目的主要目标是通过数值工艺模型和更好地理解工艺基础，实现工业磨料流加工中的优化和加速工艺设计和控制。

Abrasive Flow Machining is a process used to machine complexly shaped and hard-to-reach inner and outer contours of parts. Because of its inherently low material removal rates, Abrasive Flow Machining is solely used for surface quality improvement, edge rounding and deburring. Generally the process consists of a cyclic alternating movement of an abrasive medium over the contour of the workpiece.As of today, process design for Abrasive Flow Machining is very time-consuming and costly as optimization of the process is usually done iteratively in experiments. The potential of a numerically supported process design was shown in previous research projects. To establish the results of the previous projects in industrial applications a knowledge transfer is necessary. The knowledge transfer will be carried out on cooperation with the partner Robert Bosch GmbH. For a better understanding of the process fundamentals and a better accordance between numerical simulations and the reality a need for fundamental research in Abrasive Flow Machining is given. In this context the main goal of this research project is to enable an optimized and accelerated process design and control in industrial Abrasive Flow Machining through numeric process models and better understanding of the process fundamentals.
