All functions and controls of this three-axis CNC milling machine are realized by the above modules, among which %SP2, %SP3, %SP5 and %SP6 are the core of this machine PLC program. By designing the PLC program in a modular way, each module can be individually debugged, which improves the efficiency of machine tool debugging. When problems occur during debugging, the problem can be quickly found, and different functions of the machine tool are used with different submodules. Said that the program structure is clear at a glance. Through the separate debugging and final electromechanical joint adjustment of each sub-module, it is proved that the design idea and method of this PLC program are effective.
5 Summary
After the three-coordinate CNC gantry milling machine has been intensively debugged, the machine tool works normally and meets the requirements, and the machine tool meets the acceptance criteria. Practice has proved that the control software design of this three-coordinate machine tool is successful, and some basic modules of design and development also have good portability. In the future, the NUM1000 series CNC typical CNC machine tool PLC ladder diagram design is slightly modified. It can be used, which lays a good foundation for the design of PLC control software of the same series of CNC machine tools.
