Imaginary Axis Applications

133

While the command position of the feed axis is polluted by the
corrections with this technique, the command position of imaginary axis
is not. Thus, you can use the command position of imaginary axis as the
true command position of the feed axis for any other calculations that may
be necessary. In addition, there are no restrictions on the motion profile
used for either the feed or the correction move—any of the available
profiles can be used depending on the requirements of the application.
