Design and Implementation of CNC Lathe Automatic Processing Unit Information Model Based on OPC UA

Abstract

In recent years, CNC workshops have gradually begun to transform from industrialization to digitalization. There are various problems in the interconnection between equipment and systems of different manufacturers. To achieve smooth information transmission between CNC lathe automatic processing units, it is necessary to establish a complete, normative information model. This paper analyzes the structure information and operation principle of CNC lathe automatic processing unit, understands the advantages and disadvantages of different information model protocols, develops an information model of CNC lathe automatic processing unit that conforms to the OPC UA protocol, and realizes interconnection.
