Plate incremental forming machining method using large-angle rolling tool head

Abstract

The invention relates to a plate incremental forming machining method using a large-angle rolling tool head. The plate incremental forming machining method comprises the following steps that a closed curve track of each layer of machining track is obtained; obtaining a tangent vector of each track point according to the coordinate of each track point in the workpiece coordinate system; obtaining a normal direction vector of each track point according to the obtained tangent vector; determining the x direction of the track point coordinate system by the direction of the obtained normal direction vector, constructing the track point coordinate system by taking the direction perpendicular to the plate in the workpiece coordinate system as the z direction of the track point coordinate system, and obtaining a rotation matrix of the track point coordinate system relative to the workpiece coordinate system; obtaining an Euler angle of each track point coordinate system relative to the working coordinate system according to the rotation matrix; according to the coordinate value of each track point under the tool coordinate system and the obtained Euler angle, the large-angle rolling tool head is controlled to move, the plate is machined, and the method is high in applicability and low in control difficulty.
