The invention discloses a method for developing configuration of interfaces of numerical control systems. The method includes dividing interface systems into a plurality of modules; dividing the modules into a plurality of basic units, sorting the basic units and generating functional unit sets; carrying abstract processing on the functional unit sets and packaging the functional unit sets to form functional assemblies; constructing corresponding environments for developing the configuration of the interfaces of the numerical control systems and setting management units to manage the functional assemblies of the modules; configuring configuration of the functional assemblies by the management units and constructing configuration interfaces; carrying out simulation running on the constructed configuration interfaces and determining whether functional requirements are met by the configuration interfaces or not; loading configuration scripts and executing the configuration interfaces. According to the technical scheme, the method has the advantages that the numerical control interface systems are divided into the graphic, data and interaction modules, the corresponding independent functional assemblies of the various modules are extracted, can be instantiated in graphic visualization manners and can be combined with assemblies in the graphic visualization manners, and the configuration interfaces of the numerical control systems can be quickly constructed.
