Method and system for shortening machining cycle of steel support

The invention relates to the technical field of product machining, and provides a method and system for shortening the machining period of a steel support, and the method comprises the steps: dispatching historical defective product data corresponding to the steel support, constructing a defective product Pareto diagram corresponding to the steel support, carrying out the information mining of the defective product Pareto diagram, and obtaining chart information; inferior-quality indexes corresponding to the steel support are determined; the method comprises the following steps: collecting current index data corresponding to a steel bracket, calculating a system distinction degree corresponding to a collection system, carrying out quality management on the current index data to obtain target index data, carrying out target decomposition processing on a bracket processing target to obtain a business processing target, carrying out material pretreatment on the steel bracket to obtain a target steel bracket; col
