Abstract
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.

A method for measuring the dynamic response of a material during a machining process, the method comprising:
- receiving an excitation signal that corresponds to a force of impact of a machine tool with the material during a machining operation and is generated by one or more sensors disposed within the machine tool and configured to measure the force of impact;
- receiving a response signal that corresponds to the dynamic response of the material to the force;
- determining a vibrational characteristic of the material by comparing the response signal to the excitation signal;
- and
- adjusting the parameters of the machining operation to modify the material based on the vibrational characteristic.
