Research and development of monitoring system and data monitoring system and data acquisition of CNC machine tool in intelligent manufacturing

Abstract

Intelligent manufacturing as the development direction of the new generation manufacturing system has become a hot research topic. Computer numerical control (CNC) machine tools are the core manufacturing equipment in discrete manufacturing enterprises, collecting and monitoring the data is an important part of intelligent manufacturing workshops. It has a great significance to improve the production efficiency of enterprises and eliminate information islands. The purpose of this article is to solve the problems of data acquisition and monitoring of CNC machine tools in the manufacturing workshop of enterprises. This article uses FOCAS data acquisition method to research and develop the data acquisition and monitoring system of CNC machine tools in intelligent manufacturing workshop. The research results show that the equipment information model based on MTConnect protocol and FOCAS can solve the data acquisition and storage functions of CNC machine tools well. Using the object-oriented Petri net model, it can solve various uncertain factors in numerical control (NC) machining tasks and realize the monitoring function of CNC machining tasks in the workshop. Based on the NC program analysis, the calculation method of machining time in the NC program can determine the preventive maintenance cycle of the machine based on the machine fault information. Based on VS2013 development environment, Qt application framework and SQL Server 2012 database, the numerical control machine tool data acquisition and monitoring prototype system was developed, and the system was verified in the workshop to prove the effectiveness of the system.

A Review of Multisensor Data Fusion Solutions in Smart Manufacturing: Systems and Trends

“…In [19], a system that is capable of data monitoring and acquisition of a Computerised Numerical Control (CNC) machine tool in intelligent manufacturing was proposed and developed. Most notably, the authors compared the different data acquisition methods from a CNC machine, not only on the different data types that can be collected, but also the technical difficulty and implementation costs.…”

A novel integration between service-oriented IoT-based monitoring with open architecture of CNC system monitoring

“…Most of the developed Open CNC monitoring systems were developed through software-based Open CNC systems. The system was developed using general-purpose, objectoriented programming languages such as C, C++, JAVA, VB, and others as reported by Liu et al, 2020 [16], Jokanovic., 2020 [8], Guo and Sun., 2020 [17] and others. Meanwhile, Othman., 2020 [18]; Zhao, Cao, Xiao, Zhu, et al, 2019 [19]; Laroche et al, 2019 [20]; Kubota et al, 2018 [21] and others developed a STEP compliant monitoring system.…”

Simulation of Mechanical NC Machining Based on CAD/CAM

“…In recent years, with the development and popularization of numerical control technology and computer-aided design, analysis, and manufacturing (CAD/CAE/CAM technology, the machining industry has undergone fundamental changes, computer-aided (CAM) and CNC machining technology has become an important symbol to measure the technical level of a processing and manufacturing enterprise. Computer Aided Manufacturing (CAM) is the core of the computer integrated manufacturing system CIMS [1,2]. In fact, the function of the CAM system directly determines the success or failure of the entire product production process, and the benefits of CAD are ultimately reflected through CAM [3,4].…”
