Abstract
Currently, most of the single-point diamond bits used for turning are still manually manufactured. The profile accuracy of the diamond cutting edge depends on the operator's experiences and skills. The process is expected to be automated to improve the process stability. In this research, a fully automated grinding system has been developed to generate R-profile on the diamond bits, controlled by a vision system. The profile of the diamond bit is captured in real time via a CCD camera. The deviation from the ideal profile is calculated and converted into pulse train for feedback control. The grinding system is then able to remove the unnecessary portion of diamond bit selectively to achieve high precision and efficiency.
