Abstract

The invention discloses a system for intelligently monitoring grinding power and energy consumption and a strategy deciding method and belongs to the technical field of monitoring of machine tools. Aiming at the current situation that the grinding state is commonly judged and the grinding parameters are set and adjusted through experience manners of seeing the grinding spark and listening to the grinding sound in the current practical grinding practice, the invention discloses a software and hardware system for intelligently monitoring grinding power and energy consumption, a big data analyzing and strategy deciding system and a method thereof which are capable of monitoring and analyzing power and energy consumption in the grinding process in real time and have functions of comparing andanalyzing performance of grinding machines, grinding tools and working fluid and optimizing grinding strategies and process parameters. The system and the strategy decision method are capable of comparing the real-time grinding power and judging the relationship of size of lower limit P1 and upper limit P2 of critical power threshold, judging the grinding state and effectively analyzing and prejudging the grinding overload, passivation of the grinding tools and grinding burn. The system and the strategy decision method can be applied to grinding materials, grinding tools and grinding-related manufacturing industry; the intelligent production with high efficiency and lower energy consumption can be facilitated.

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 precision manufacturing 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 efficiency. In a...
