OPC 40502-1 CNC Systems


Information Model to exchange data with Computerized Numerical Control (CNC) systems.
CNC systems are used to control machine tools and machining centers. The CNC system is mainly responsible for generating a relative movement between a tool (e.g cutting tool) and a workpiece. Therefore, the CNC system implements functionality to provide setpoints to a machine tool’s drives that realize the generated movement physically.
CNC systems are in most cases executed in combination with Programmable Logic Controllers (PLC). Whereas the CNC is responsible for the tool path generation, the PLC implements auxiliary functionality (mostly logical operations like activating lubrication at a certain time) and controls the peripheral devices.
