Abstract
In robotic belt grinding of the blisk, the presence of deep and narrow flow channels poses a risk of abrasive belt collisions, potentially causing damage to the tool and blisk. Therefore, a collision-free tool posture generation method is proposed. This method involves discretizing the processing surface into cutter contact (CC) points and establishing local coordinate systems at each CC point. By employing OBB-Tree and leveraging the structural characteristics of the abrasive belt, an efficient collision detection method is developed to establish the relationship between tool posture and the blade. The collision-free posture of the abrasive belt is then determined using a dichotomous method. The feasibility of this approach is verified through a simulation system developed using Visual Studio and VTK (Visualization Toolkit).
