    helical interpolation 15m

    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.

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

    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.

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

    I do have the tooling
