Need Help!- G71 on fanuc 10T

[SCHMIDT]

Hi everyboby. I'm new here and really hope you can help me...

when running following program the machine seems to disregard all the roundings and just run in straight lines from start to end dia.
but in G70 and simulation on the pc it works right??

Try using R instead of I and K
Use pythagoras to convert to R
SQRT(I^+K^)

[rapidtraverse]

Have you ran the g-70?

G-71 may not cut your arc's as it is primarillary a roughing routine and often will not cut arc's.

[CNCRim]

The max execution for G70 is 50lines, ur rough cycle is too long. Try R instead I and K some machine don't support it.

[eject_21]

Really? 50 lines max??? I've never had more than 10 or 12, but that's a pretty useful piece of information to me. Thanks 2006.

G71 Syntax is

N1 G71 U( ) R( )
N2 G71 P100 Q300 U0.5 W0.025 F0.2
N100-N300 GEOMETRY. WHAT I'M SAYING IS THAT YOU SHOULD SET DEPTH OF CUT(U)
AND REMOVE DISTANCE OF THE TOOL ON PASSES (R).

[zicci]

Yes you should indicate depth of cut in G71 Cycle
If you use OT Control then doc is U2.( per side ) R.5 ( must be less than
value in U ) This is only the cut retract value.
If you use 6T Control then everything including doc is specified in
G71 line ie D2000 ( without decimal point ),in 6T Control retract value
is set with parameter
Hope this helps
