| Abstract | |
In the past, deburring used to be treated as a secondary operation within the manufacturing sequence of a part. However, the industry came to realize its importance, which becomes the motivation for this study. In the literature, several solutions for burr minimization and automatically burr removal can be found. However, some topics need more investigation in order to establish a final solution. Thus, the main objective of this research is to identify these topics and to propose solutions for each of them. Therefore, a new algorithm for drilling burr minimization will be defined, based on a vibratory movement of the tool in feed direction. Additionally, it is proposed to identify the real requirements of the deburring operation and to classify the deburring problem into classes with similar characteristics, taking into account: burr morphology, workpiece geometry and precision of the fixture system. Subsequently, for each class, a robotic deburring solution is proposed. In the case of active robotic control, a new control parameter will be defined (Fast Abrasive Power, FAP) based on the fusion of acoustic emission and power signals. (AU) | |
