6.16 HYPOTHETICAL AXIS INTERPOLATION
General
Sinusoidal interpolation can be performed by using a circular
interpolation axis of helical interpolation as a hypothetical axis and
distributing pulses.
By using a circular interpolation axis as a hypothetical axis and
distributing pulses, the travel speed about the remaining axis can be
changed sinusoidally. If the longitudinal axis of threading (axis of the
greatest travel amount) is set as a hypothetical axis, a fractional thread
can be formed. The axis to be set as the hypothetical axis is specified
by G07.
