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.

I have this same problem with a fanuc 15m.Any help on the parameter for this would be greatly appreciated. Thanks
