NC FUNCTION
54
In helical interpolation, when pulses are distributed with one of the
circular interpolation axes set to a hypothetical axis, sine interpolation is
enable.
When one of the circular interpolation axes is set to a hypothetical axis,
pulse distribution causes the speed of movement along the remaining axis
to change sinusoidally. If the major axis for threading (the axis along
which the machine travels the longest distance) is set to a hypothetical
axis, threading with a fractional lead is enabled. The axis to be set as the
hypothetical axis is specified with G07.
