<p>A device for boring a non-round hole that measures a shape of a hole of a non-round cross-sectional shape already formed, and forms another hole in a work of a shape identical to the hole already formed and measured, the device comprising:
a Bode diagram storage means (52) for storing a Bode diagram plotting a relationship between a drive frequency of a processing head and a gain and phase lag of the processing head as a Bode diagram map;
an error parameter calculation means (42) for obtaining frequency components from 0 th order to n th order of an applied drive frequency of the processing head, and calculating, based on the Bode diagram map, a gain and phase lag of each of the frequency components based on the Bode diagram, as an error parameter; and
an error parameter storage means (52) for storing the error parameter thus calculated by the error parameter calculation means (42) .</p> |
