3.6 Helical Interpolation (G02/G03)
Helical interpolation which moved hectically is enabled by specifying up to two other axes
which move synchronously with the circular interpolation by circular commands.
Format:
Synchronously with arc of XpYp plane
Synchronously with arc of ZpXp plane
Synchronously with arc of YpZp plane
α,β: Any one axis where circular interpolation is not applied.
Up to two other axes can be specified.
The command method is to simply or secondary add one more command axis which is not
circular interpolation axes. An F command specifies a feed rate along a circular arc. Therefore, the
feed rate of the linear axis is as follows:
Arc
Circular
of
Length
Axis
Linear
of
Length
_
_
_
_
_
_
*
F
Determine the feed rate so the linear axis feed rate does not exceed any of the various limit
values. Cutter compensation is applied only for a circular arc.Tool offset and tool length
compensation cannot be used in a block in which a helical interpolation is commanded.
