Three-dimensional soft model cutting forming machine and method

The invention discloses a three-dimensional soft model cutting forming machine and a three-dimensional soft model cutting forming method using the forming machine to achieve high efficiency machining, wherein the three-dimensional soft model cutting forming machine is compact in structure, and smooth and fast to machine. The forming machine comprises a base, a stand column, a fixed cantilever, a movable cantilever, an angle cutter head base and a cutter head body. The stand column is installed on the base through a first guide drive mechanism and can reciprocate along the horizontal X axis, the fixed cantilever is installed on the stand column through a second guide drive mechanism and can reciprocate along the horizontal Y axis, the angle cutter head base is installed at the front end of the movable cantilever through a fourth guide drive mechanism and can swing in the two directions around a first reference axis parallel to the horizontal Y axis under the action of the fourth guide drive mechanism, and the cutter head body is installed on the angle cutter head base through a fifth guide drive mechanism and can swing in the two directions around a second reference axis perpendicular to the first reference axis under the action of the fifth guide drive mechanism.
