9 MAJOR POSITIONING CONTROL
[1] 3-axis helical interpolation control with center point designation
(ABS helical right, ABS helical left)
Operation chart
In this control, positioning is carried out from the current stop position (X0, Y0, Z0)
to the circular end address (X1, Y1) and linear axis end address (Z1) set in
" Da.6 Positioning address/movement amount". Circular interpolation with an arc
path having its center as the address of the center point (arc address) set in
" Da.7 Arc address" is carried out. Simultaneously, linear interpolation is carried
out with the other linear axis. The control path is helically rotated for the number of
pitch set in " Da.10 M code" of the linear axis to complete the positioning to the
specified position.
Operation chart Circular interpolation plane
Positioning of a true circle with a radius of the distance from the start point address
to the arc center point can be carried out by setting the end point address
(positioning address) of the circular interpolation axis to the same address as the
start point address.
