Abstract

The invention discloses a grinding power and energy consumption intelligent monitoring system and a decision-making method, belonging to the technical field of machine tool monitoring. Aiming at the current actual grinding process practice, mainly through the experience of looking at the grinding sparks and listening to the grinding sound to judge the grinding state, set and adjust the grinding parameters, an intelligent grinding power and energy consumption is invented. Monitoring software and hardware systems, big data analysis and decision-making systems and methods, to achieve real-time monitoring and analysis of power and energy consumption during the grinding process, with performance comparison and analysis of grinding machines, grinding tools, working fluids, and grinding processing strategies and processes Parameter optimization function. By comparing the real-time grinding power with the lower limit of the critical power threshold P 1 and upper limit P 2 The relationship between the size and size of the grinding machine can be judged, and the effective analysis and prediction of grinding overload, grinding tool passivation, and grinding burn can be realized. The invention can be applied to abrasive materials, abrasive tools and grinding-related manufacturing industries to promote the realization of high efficiency, low energy consumption and intelligent production.

Description

technical field [0001] The invention relates to a machining monitoring system and method, in particular to a grinding power and energy consumption intelligent monitoring system and a decision-making method, belonging to the technical field of machine tool monitoring. Background technique [0002] Grinding technology can obtain high surface quality and machining accuracy efficiently and at low cost, and has been widely used in industrial fields such as aerospace, automobiles, ships, precision instruments, nuclear energy, optoelectronics, and semiconductors. At present, grinding accounts for about 70% of the precision manufacturing field, and is one of the most important pillar processing technologies. However, due to the uneven wear of a large number of irregular abrasive grains on the surface of the abrasive tool, grinding is a complex and extremely unstable process. Influenced by other factors, it is difficult to precisely control the grinding quality and processing effici...
