| Abstract: | An on -line monitoring system of tool breakage in numerical control cutting was put forward, and the principle of monitoring tool breakage using current signatures and the experimental set - up was introduced. The application of interruption type custom macro function on the on - line monitoring system was discussed. Experience indicates that the system can identify tool breakage real - time, givie an alarm and replace tool. The downtime of machine malfunction is cut down greatly and the efficiency of machine is increased greatly. |
