G68.2 G43.4

[mk2456]

Hello together,

i hope somebody here could help me.

We are having a OKK 5 axis machine with  a Fanuc 310is Model A5 control. LLast week Fanuc installed us the G68.2 option on the control but without setting any parameter.

I have checked the parameters 19700 for X/Y/Z and there are values standing in according to G54.000

Everything is working till we want to machine simultan then we are having a problem.

Here is the code what we get out from the PP for the machine:

N10 G90 G94 G17 G49 G40 G80
N15 G21
N20 G28 G91 Z0.
N25 G90
N30 G00 A0. C0.

N35 T45 M106
N40 S4775 M03
N45 G17 G90 G94
N50 G54
N55 G00 A-90. C6.472
N60 G68.2 X0. Y0. Z0. I-173.528 J90. K180.
N65 G53.1
N70 G00 X0. Y-1.496
N75 G69 

till here everything is fine but at the line N80 he activates G43.4 and then he looses the coordinate system and he is going to the home position of the machine
N80 G43.4 H45
N85 G00 X-3.663 Y32.293 Z1.496 A-90. C6.472
N90 X-2.536 Y22.357
N95 G01 X-2.063 Y18.183 F230.
N100 X-1.507 Y13.288
N105 Z-36.918 F430.
N110 G00 X-3.663 Y32.293
N115 G28 G91 Z0.
N120 G90

DM me your machine's parameters.

 

When FANUC installs options, they DO NOT configure the parameters for the machine. That is the builder/dealer/end-user's responsibility.

SHOT IN THE DARK, FREE ADVISE TAKE IT AT FACE VALUE

 

Maybe parameter 19696.5,19746.4, 19754.5. All needed adjustment on my Mori's when we went to the postibility post that utilized G68.2 into a G43.4 move

But getting James involved is the greatest of all moves. He has fixed more things with my machines then the actual MTB
