Systems, methods, and computer readable media for sheet registration in a tractorless sheet processing device using existing sheet features are disclosed herein. In some aspects, the systems can include a tractorless sheet processing device having a cutter for cutting individual sheets from continuous form material and a cutter feeder for feeding the continuous form material to the cutter. The systems can also include a camera disposed relative to the cutter feeder and configured to capture an image of a position of at least one existing sheet feature on at least one or more of the individual sheets of the continuous form material in order to synchronously register each of the individual sheets with the cutter, and a controller including at least one hardware processor and memory, the controller being configured to interface with the camera and the tractorless sheet processing device.

A machine implement includes sensors that measure a force imparted by the machine implement to a structure during a machining process. A sensor array coupled to the structure measures the vibrational response of the structure to the imparted force. Analysis software compares the imparted force to the vibrational response to generate a transfer function for the structure. Based on the transfer function, a tool-path of the machine implement may be adjusted such that the resulting structure has precise vibrational characteristics that substantially comply with a set of design goals for the structure.
