1. An incremental sheet forming system that is configured to form a structure through an incremental sheet forming process, the incremental sheet forming system comprising:
a forming control unit including one or more processors, wherein the forming control unit compensates for spring back of a structure to be formed through the incremental sheet forming process by modifying at least a portion of a toolpath of a forming tool that is used to form the structure based on the spring back, wherein the forming control unit determines and generates a tool-offset surface that is separate, distinct, and spaced apart from a sheet offset surface that is separate, distinct, and spaced apart from a target surface and the tool-offset surface, and wherein the tool-offset surface includes the toolpath.
