Programming
Multi-turn helical interpolation
If the helical interpolation is to make several turns, besides
programming the circular interpolation in the active work plane and the
linear movement of the other axes, the helical pitch must also be
programmed.
When defining the center of the circular interpolation, it is not
necessary to define the coordinates fo the end point in the work plane.
This point will be calculated by the CNC depending on the height and
pitch of the helix.
Pass definition
The helical pitch is defined using the letter "I", "J" or "K" associated
with 3
rd
axis of the active work plane.
The programming format depends on the active work plane. In the XY
plane is:
G17 G18 G19 The pitch is defined with the letter "K" (G17), "J"
(G18) or "I" (G19).
G20 The pitch is defined with the letter "K".
