Background

The human-computer interface is a medium for mutually transmitting information between a user and the machine tool and is used for realizing the input and output of the information. The Siemens numerical control system is a control system integrating various numerical control system elements into a whole in an operation panel installation mode, but is only limited to simple application of a Siemens standard numerical control system and a shallow layer, so that special requirements of high-grade equipment such as a roller grinder cannot be met, the Siemens numerical control system cannot give full play to the performance, and meanwhile, the high-grade benefits of the numerical control machine cannot be given full play to.

The information feedback module realizes that an operator strictly controls various conditions in the machining process. These conditions include whether each coordinate axis reaches a predetermined position, an operation state of a feed shaft, a state of a PLC, alarm information, and the like.

The parameter setting module is mainly used for editing R parameters.

The fault processing module is used for processing various faults occurring in the processing process in time. When the system detects a fault, an alarm signal is displayed to prompt an operator which part has the fault, and the system has manual processing and automatic processing functions. The fault processing function module also needs to have a function of simulating a fault, namely, if a certain type of fault is assumed, whether a corresponding emergency measure is automatically taken by the diagnosis system or not is judged.

The dynamic link library module does not appear on the interface, but is an important link in the system, and the design of the dynamic link library module is related to the control function of the whole system. Due to the existence of the system, the software and hardware design is more independent in division of labor and stronger in modularization.
