When double thin-walled parts with connecting ribs are formed,the bump defects are easy to occur in the connection between ribs and thin walls.The bump defects will be more obvious with the accumulation if the control is improper,and it is easy to lead to accumulation failures.We propose a lateral lap process by equal volume method,which can obtain intersecting surfaces of ribs and walls with flat cladding morphology by controlling the starting and stopping offset in the nozzle scan path to control the late...
