High stiffness and high access forming tool for incremental sheet forming
An tool for the incremental forming of material sheeting is disclosed. The tool comprises a forming tip, a shank, and an interface adapter positioned between the forming tip and the shank. The forming tip has a diameter and the shank has a diameter. The diameter of the forming tip is greater than the diameter of the shank. The forming tip may be of a variety of configurations. The forming tip may be donut-shaped. The donut-shaped tip may have a recessed area formed therein. The recessed area may be frustoconically shaped. As an alternative to the forming tip being donut-shaped, the forming tip may be made up of at least two forming spheres. An adapter is provided to which the spheres may be attached either directly or by arms. The diameters of the spheres may be the same or may be different diameters.
1. A tool for an incremental forming of a sheet of material, the tool comprising:
an adapter having a first diameter, said adapter having an outer periphery;
a shank to which said adapter is attached, said shank having a second diameter, said first diameter of said adapter being greater than said second diameter of said shank; and
a first and a second ball-end tip directly attached to said outer periphery of said donut-shaped adapter, each of said ball-end tips having a different diameter,
wherein said adapter and said first and second ball-end tips lie in a first axial plane,
wherein said shank and said adapter lie in a second axial plane, said first and second axial planes being perpendicular to one another.
2. The tool for an incremental forming of a sheet of material of claim 1 , wherein the diameters of each ball-end tip range from 6 mm to 25 mm.
3. The tool for an incremental forming of a sheet of material of claim 1 , further comprising a third ball-end tip directly attached to said outer periphery of said adapter.
4. The tool for an incremental forming of a sheet of material of claim 3 , wherein the diameters of each ball-end tip range from 6 mm to 25 mm.
