A Robotic Belt Grinding Force Model to Characterize the Grinding Depth with Force Control Technology

摘要

In the present paper, a new grinding force model is developed by analyzing and assessing the robotic abrasive belt grinding mechanism which is based on the fact that the chip formation during grinding process consists of three stages: ploughing, cutting and sliding. Then the grinding depth is predicted by the grinding force model to realize quantitative machining in the robotic belt grinding process. Next the grinding parameters optimization are implemented to further ensure the workpiece surface quality and profile accuracy with force control technology applied. Finally, a typical case on robotic abrasive belt grinding of test workpiece and aero-engine blade is conducted to validate the practicality and effectiveness of the grinding force model.
