The application provides a steel bridge part manufacturing method, device, equipment and medium, and relates to the technical field of bridge manufacturing. The method comprises the following steps: acquiring basic information corresponding to each plate part in a steel bridge; generating a contour map of the plate part based on a three-dimensional model of the plate part, determining a target allowance corresponding to the plate part by using process attribute information and a preset allowance addition rule
library, and modifying the contour map to obtain a target contour map according to the target allowance; generating a
layout scheme based on the target contour maps corresponding to all plate parts; generating a
processing instruction according to the
layout scheme, and sending the
processing instruction to a corresponding preset
processing equipment, so that the preset processing equipment processes a mother plate according to the
processing instruction. The application can realize integrated operation of each manufacturing link of the steel bridge part, and effectively improve the efficiency and quality of the steel bridge part manufacturing.
