was woundering if anybody has experience with this control? I have ran just about everything except this control. The programming manual has you pre-setting all the tools an then creating the program by adding and subtracting tool lengths, like there is no coordinate setting feature. I seen where it uses G92's, but it only shows it applying to the Z axis. Can you use G92 like G50?

Thanks in advance.

ran "Victor" lathe for a while with Fanuc 10T control and noticed that G92 was being used in place of G50.
G92 is a threading cycle in "A" group of G code and same as G50 in "B" G code group, I have no clue as to why these two were mixed as they were, control had geometry offsets and G92 was being used only to set RPM limit.

Back in early 1990 I ran an old Hitachi lathe with Fanuc 6T control that had no geometry offsets. The way to set tools was fairly simple and reliable, all X and Z values for tool lengths were on G50 line at the start of every sequance and tool was driven back to it's starting location before calling another tool.

N2(CNMG432,FACE OFF)
T0101
G50 X4.654 Z3.457 S2000 M42
G96 S450 M03
G00 X2.1 Z.1 M08
Z.005
G01 X-.062 F.012
G00 Z.1
X4.654 Z3.457 M09
T0100
M01


If tool was not taken back to it's start point then next G50 call would simply assume that current location is the indexing point and next tool would be driven in X and Z distances given on that G50 line , which basicly means crashing the machine.
I don't know if any of this is what you were after but that's how it workes on old machines I dealth with at a time.
