A dual sided incremental sheet forming method for incrementally forming sheet materials such as sheet metal that provides opposed primary and secondary forming tool assemblies. The primary forming tool assembly provides a rigid tool and the secondary forming tool assembly provides a compressible and resilient backing layer. The rigid tool applies force to one surface of the sheet material while the resilient backing tool applies counter force to the opposite surface of the work piece as it supports the work piece along predetermined, successive paths of formation created as the primary forming tool assembly moves relative to the sheet material. The direction of travel of the primary forming tool relative to the sheet material is alternated either as to each successive path of formation, or as to predetermined groupings of paths of formation.

TILED BACKING MAT SYSTEM FOR AN INCREMENTAL SHEET FORMING SYSTEM WITH RESILIENT TOOLING
A resilient compressible tiled backing mat system used in an Incremental Sheet Forming (ISF) System, the ISF system having a primary rigid forming tool assembly and a backing flat tool assembly including a flat rigid plate for releasably holding the tiled backing mat that is compressed in response to force provided through a work piece by the primary forming tool. The tiled backing mat includes a plurality of individual tiles arrayed in a packed or nested pattern and being releasably secured to the flat rigid plate via a magnetic layer of the tiles. Individual tiles are easily replaced if damaged or worn without replacing the entire mat. Tiled backing mat configurations can be sized according to the area of the flat rigid plated and/or the particular machine area required for forming a selected work piece.
The present invention is directed to a dual sided incremental sheet forming apparatus and method for incrementally forming sheet materials such as sheet metal by utilizing opposed primary and secondary forming tool assemblies and a sheet feeding assembly. The primary forming tool assembly includes a rigid tool and the secondary forming tool assembly includes a compressible and resilient backing layer having either a cylindrical or flat configuration. The sheet feeding assembly positions the sheet material between the two forming tools. The rigid tool applies force to one surface of the sheet material while the resilient backing tool applies counter force to the opposite surface of the work piece as it supports the work piece. This dual sided process localizes the forces on the sheet material so that stresses are advantageously controlled to produce accurately formed asymmetric shapes, without the need for expensive dies. The use of a rigid tool with an opposed resilient backing tool both having linear independent motion also avoids potential wrinkling and tearing of the resulting work piece and enables the formation of numerous, highly detained asymmetric products.

INCREMENTAL SHEET FORMING SYSTEM WITH RESILIENT TOOLING
The present disclosure is directed to a dual sided incremental sheet forming apparatus and method for incrementally forming sheet materials such as sheet metal or plastic. A primary forming tool assembly having a tool shaft with a tip and a secondary forming tool assembly includes a compressible and resilient surface layer, the primary forming tool assembly, secondary forming tool assembly and/or work piece are movable such that the primary forming tool assembly moves along a predetermined set of coordinates parallel to the X-Y plane with the tip in contacting relation with the work piece at substantially the same Z coordinate. The rigid tool applies force to one surface while the resilient backing tool applies counter force to the opposite surface of the work piece which localizes the forces to produce accurately formed asymmetric shapes, without the need for expensive dies while avoiding potential wrinkling and tearing of the resulting work piece.
