Fanuc 0i cylindrical interpolation

[f-bu]

Hi all, I've got in the middle of nowhere trying exaple for cylindrical interpolation in 0i manual. Machine is VMC, additional axis A on X axis Do someone know how to assign A axis as virtually paralell to basic axis? When I assign it as parallel to X(1022.A=5), G02 X.. A.. R.. makes circle in Y and A, X is substituted by Y. When it is assigned to Y, 1022.A=6, then the circle is made on X an A, but X axis movement is increased, not A. Any practice on this?

I think Haas is similar to Fanuc. On a Haas control the code is G107 A0. Y0. Q6.
"A" is the rotary axis (A or B) "Y" is the axis to convert to rotary ( X or Y )and "Q" is the diameter of the cylinder or "R" is the radius of the cylinder. You then program your path the same as a flat surface and the control does the rest.
I am wandering if your G107 Cyl. Interp call is correct.
Can you post the code you using for mapping your cylinder.
I am picturing this as a rotary table mounted on your table, not a true in-table rotary. The linear axis is along the "X" axis and the cylinder mapping is along the "Y" axis.

Here is it
...
G1G17X0A21.F1000
G43H11Z2.S3000M3
G1Z-3.F500
G07.1A97500
G2X0A-21.R21.
(in this point X axis moves not 21mm, but 21*2*pi/360)
...
G07.1A0

I am speaking only from my experience with Haas but I don't think you use an A word in your code after you call G107 or in your case G07.1
On a Haas you program the shape of your part in X-Y-R just like you would on a flat surface and the control converts the Y value into the A value based on the Y value and the Radius (R) or Diameter (Q) of the cylinder that you enter in your G107 Y0.0 A0.0 R2.0 cylinder interpolation call line.
Here is the example from the Haas manual. This code cuts a 4.0 X 2.0 window with 0.5 corner radii in a 4.0 inch diameter cylinder. It wraps the 2.0 inch side around the Y axis and the 4.0 inch side is straight along the X axis.
