Problems solved by technology
[0002] The working conditions of superhard material tools during high-speed milling are generally harsh, and they often need to withstand cyclic loads and alternating temperature changes of cold and hot. Repeatedly changing thermal stress and thermal strain will occur inside the tool material, which will cause thermal fatigue of the tool material. Easy to break and break, low tool life

The invention discloses a heat fatigue crack monitoring system for a superhard tool. The system comprises a data collection and acquisition system and a crack state monitoring system, wherein the data collection and acquisition system comprises a dispersed control system (DCS) and a remote I / O data collection module; the crack state monitoring system is an embedded monitoring platform of a multi-Agent based technology; the multi-Agent based technology comprises a dispatch Agent, a management Agent, a service Agent, a crack Agent and a resource Agent; the DCS and the remote I / O data collection module communicate through a Modbus protocol and the embedded crack monitoring platform of the Agents; the multi-Agent based technology finishes monitoring and diagnosis of the heat fatigue cracks of the superhard tool in a machining process; and data collected from the platform is analyzed and preprocessed and then is transmitted to a workstation of a control center through the Ethernet to be monitored and managed, and meanwhile the data is stored in a real-time or historical database of a database server. Therefore, the system is capable of monitoring the heat fatigue crack state of the superhard tool in real time.
Description
technical field [0001] The invention relates to a monitoring system in mechanical engineering, in particular to a superhard cutting tool thermal fatigue crack monitoring system. Background technique [0002] The working conditions of superhard material tools during high-speed milling are generally harsh, and they often need to withstand cyclic loads and alternating temperature changes of cold and hot. Repeatedly changing thermal stress and thermal strain will occur inside the tool material, which will cause thermal fatigue of the tool material. Easy to break and break, low tool life. [0003] For this reason we have studied a kind of superhard tool thermal fatigue crack monitoring system; Described a kind of superhard tool thermal fatigue crack monitoring system comprises based on multi-Agent technology; Described based on multi-Agent technology is a kind of having autonomy, reactivity, Active and highly autonomous entities, each Agent can independently complete its own wor...
