The invention discloses a technological method for determining technological consumption quota of a special vehicle board and belongs to the technical filed of special vehicle board cutting blanking technologies. The technological consumption quota of the board can be definitely obtained. The method comprises the steps that a board-size basic database is established, material quota is made, technological parameters are calculated, a technological parameter table is formed, the blanking sizes of parts are determined, a thickness value for calculation of the technological material quotas of the parts is determined according to the requirements of a design drawing, and other steps. By determining a board edge-shared cutting principle, blanking margin, separation distances of cut parts, a board-size prior selection principle and the like, the accuracy of the technological consumption quota is ensured, rapid and efficient technological material consumption quota determination is achieved, the problem of low board cutting blanking efficiency is solved, accurate and efficient raw material processing is achieved, and product cutting precision and raw material utilization rate are improved.
