The display in a CNC digital readout system serves as the interface between the operator and the machine, providing essential information about the machining process in a clear and understandable format. Its primary role is to present real-time data regarding the position, movement, and status of machine tool components. The display allows operators to monitor machining operations, track tool paths, and verify the accuracy of machining processes. Additionally, it provides a platform for inputting commands and parameters, enabling operators to control and adjust machine settings as needed.
