Greetings,
It is well known current TCM systems that detect tool breakage within one second. However, in high-speed machining, the workpiece surface integrity may be impaired. How to achieve the tool breakage detection methods with milliseconds level time response or faster?

Yes, it is true that in high-speed machining, tool breakage detection systems that respond in one second or longer may not be sufficient. This is because during high-speed machining, the tool is moving very quickly and the time between the occurrence of tool breakage and the detection of the problem may be very short. In such cases, the workpiece surface integrity may be impaired if the tool breakage is not detected quickly enough.
To address this issue, several methods can be used to detect tool breakage with faster response times, typically within milliseconds. These methods include:
Acoustic emission (AE) sensors: AE sensors can detect the high-frequency acoustic signals generated by a broken tool with very high sensitivity and in real-time. The response time of AE sensors is typically in the range of microseconds to milliseconds, which makes them suitable for high-speed machining applications.
Force sensors: Force sensors can detect changes in cutting forces caused by tool breakage in real time. The response time of force sensors is typically in the range of milliseconds, which makes them suitable for high-speed machining applications.
Vibration sensors: Vibration sensors can detect changes in tool vibration caused by tool breakage in real time. The response time of vibration sensors is typically in the range of microseconds to milliseconds, which makes them suitable for high-speed machining applications.
Infrared cameras: Infrared cameras can detect the heat generated by friction between the tool and the workpiece during machining. If the tool breaks, the heat generated by friction decreases, and this change can be detected by an infrared camera. The response time of infrared cameras is typically in the range of milliseconds, which makes them suitable for high-speed machining applications.
Using these methods, it is possible to detect tool breakage with faster response times, which can help prevent damage to the workpiece surface during high-speed machining.
