PROCESSING AREA DIVIDING AND PROCESSING METHOD FOR ADDITIVE MANUFACTURING APPARATUS HAVING MULTIPLE PROCESSING HEADS

摘要

A processing area dividing and processing method for an additive manufacturing apparatus having multiple processing heads, allowing a smart delineation of a scan area of a large-format complex cross-section, comprising the steps of: S01, determining closed area A comprising all closed patterns in the cross-section of a certain layer of a processing part and N the number of processing heads; S02, determining a point in the closed area, dividing closed area A into N quadrants with the point as the point of origin, ensuring that the closed patterns that each quadrant comprises are identical in area, each quadrant corresponding to one scan processing head; in step S02, if a closed pattern is continuously distributed in two or more adjacent quadrants, then re-dividing scan areas in each of the adjacent quadrants, thus ensuring that different scan heads are prevented from scanning in adjacent areas at the same time, and reducing heat input in a same area. The method of the present invention has the advantages of high processing efficiency and reduced heat accumulation.
