支持物联网的智能切削刀具视觉在线监测系统

Support IoT Intelligent Cutting Tool Vision Online Monitoring System

针对国内数控加工中心刀具管理混乱、刀具损耗严重进而导致加工工件次品率急剧上升等实际问题,结合国内外智能切削刀具的研究现状和发展水平,提出一种支持物联网的智能切削刀具视觉在线监测系统。该系统构建支持物联网的机器视觉刀具磨损在线监测,采用Zig Bee技术组建无线传感器网络,通过机床关键部位安装的传感器,实现数据的实时传输。通过以太网传输到智能管理系统,并对在线视觉监控和实时传输数据进行分析与整理,完成对刀具生命全周期的在线监测和管理,在保证加工质量的同时提高加工效率和降低成本。

Aiming at the chaos of tool management in domestic NC machining centers and the serious tool wear which leads to the sharp rise of the defective rate of workpiece, a vision on-line monitoring system for intelligent cutting tools sup- porting intemet of things is proposed. The system constructs a machine vision tool wear on-line monitoring system supporting the Internet of Things, uses Zig Bee technology to build a wireless sensor network, through the key parts of machine tools in- stalled sensors, to achieve real-time data transmission, through Ethemet transmission to the intelligent management system, and finally on-fine visual monitoring and real-time transmission number. According to the analysis and finishing, the on-line monitoring and management of tool life cycle is completed, which can improve the machining efficiency and reduce the cost while guaranteeing the machining quality.
