1. An assembly for vibrating a tip of an ultrasonic surgical tool, the ultrasonic surgical tool having at least one driver to which an AC drive signal is applied to vibrate the tip, the tip being designed to vibrate in plural vibratory modes, the assembly including:
an assembly for generating a variable AC drive signal that is applied to the at least one driver of the ultrasonic surgical tool; and
a processor configured to:
read from a memory associated with the tip data indicative of at least one drive signal characteristic for each of the vibratory modes; and
assert a command to the assembly that generates the AC drive signal so as to cause the assembly to generate an AC drive signal that contains a component for each of the vibratory modes that is based on the at least one drive signal characteristic indicated by the read data for the vibratory mode.
