helical interpolation 15m

[Goran P.]

Hi,

a couple of years back i had a problem getting my machine (with fanuc 16i) to cut arcs while feeding in z at the same time. The problem was solved by changing the parameter #9930 from 01000111 to 01001111.

Now, different machine same problem...

I'm using a fanuc 15m controller, would anyone have an idea which parameter i would have to change? Here is the same example as before:

T1
M06 ( 2" MITSUBISHI)
G00 G90 G54 X0. Y0. S700 M03
G43 H1 Z2. M08
Z.1
G01 Z0. F45.
G03 Y.4685 I0. J.2343
Y-.4685 Z-.025 I0. J-.4685 (This is where I get the alarm)
Y.4685 Z-.05 I0. J.4685
Y-.4685 Z-.075 I0. J-.4685
Y.4685 Z-.1 I0. J.4685
Y-.4685 Z-.125 I0. J-.4685
...


The alarm I am getting is; 021 Illegal Plane Axis Commanded

Thanks!

Helical interpolation might be an option. Somebody may PM you the option parameter.

Your program is for G17.

pm sent to you !

You are defaulted by g17 which is x y plane. Xz is g18 and zy is g19.

Thanks for the PM.
Everything is working good now.

Never have tried in depth the helical interpolation except to make a part with a 1.25" hole in the wide center web of a z shape extrusion.

I too have a 15M.

I would like to try threadmilling with helical interpolation with a inserted tool. Vargus/Carmex.

I do a lot of thread milling.Once you use it you cant go back.

Neat, I'll have to try something like that. 8tpi and 16tpi and 20tpi I do frequently.

I do have the tooling

[megaman26]

I also just ran into the same issue on fanuc 15m. Any help with the option parameter is greatly appreciated.

Me too please

[zx980]

Anyone have the parameter info for changing this? Running into the same issue....

[memoryman]

send me an pm.

I also just ran into the same issue on fanuc 15m. Any help with the option parameter is greatly appreciated.

I also have the same problem if you could please pm me the parameter to change it would be massively appreciated. Thanks again
