4.10.5 3-axis helical interpolation control with sub point designation
Helical interpolation control with sub point designation (ABS) (3-axis helical interpolation control with sub point designation)
In the absolute system and 3-axis helical interpolation control with sub point designation, the
positioning is performed from the current stop position (X0, Y0, Z0) to the position indicated
with the arc end point address (X1 and Y1) and the linear interpolation axis end point
address (Z1) set in "[Da.6] Positioning address/movement amount". As the positioning to the
commanded position, the linear interpolation with the other linear interpolation axes is
performed and the positioning target is rotated helically for the number of pitches set in
"[Da.10] M code/Condition data No./Number of LOOP to LEND repetitions/Number of
pitches" of the linear interpolation axis while the circular interpolation through the sub point
address (sub point address) set in "[Da.7] Arc address" is performed.
The resulting path is an arc whose center is the intersection point of the perpendicular
bisectors of a straight line between the start point address (current stop position) and sub
point address (arc address) and a straight line between the sub point address (arc address)
and end point address (positioning address).
