Non-circular X G727

G727 is used to machine elliptical polygons.
The turning contours are programmed using separate turning
cycles.
Refer to your machine manual.
This function is set by your machine tool builder.
Prerequisites:
Synchronizing Functions software option
Parameters:
H: Activate coupling
H = 0: Deactivate coupling
H = 1: Activate coupling
Q: Reference spindle – number of the spindle coupled with
axes X and Y (machine-dependent)
I: X stroke +/ – half of overlapping X movement (radius value)
C: Center offs. of C at Z start – C-axis angle of the X stroke
F: Max. rapid traverse – permissible rapid traverse for X and Y
axes with activated coupling
E: -Form factor? – number of X strokes with respect to one
spindle revolution
Z: Z start – reference value for the parameter C
W: Delta C [°/mm Z] – difference in C-axis angle with respect
to a distance of 1 mm in the Z axis
Danger of collision!
When the coupling is activated, the control positions the tool in
the Z axis to the value of the parameter Z. Danger of collision
during approach!
Pre-position the tool if required before activating the coupling
(before the cycle)
