G83 cycle on mori SL-15

[positiverake]

Machine won't run a G83 unless you swicth to a G17 XY plane? this is a fanuc 10T control, also cant find I.D./O.D. swicth? always had a keyed switch, found dry run and others in the settings screen but no clamp direction? were can I find manuals for this machine?

If you're drilling on the face it should be a G18 for the G83, if you're drilling from the side I believe it's a G19 and a G87 instead of a G83. The O.D./I.D. chucking selection will be selected in the custom page.

Thanks for the reply, this is a 2 axis lathe with no live tooling, thats why I dont know why you would have to change planes? where is the custom page? this is a fanuc 10T control.

I don't beleive that G83 drilling cycle will work on a lathe.

You need to use a Macro if you have Macro B or make a sub program to do each peck.

You could always use G74 which is similar to G73 on a mill.
( example below )

(11/16 HSS DRILL)
N280T0909
N290G54
N300G97
N310S499M3
N320M8
N330G0X0.0Z.05 ( position to material center, and .050 from face )
N340G74Z-1.060K.185F.006 ( Z is depth of drilled hole, K is the peck, F is feed per rev. )
N350G0Z1.
N360G0Z3.
N370M9

As far as ID OD chucking, I think that is located under the PC/NC button on the bottom right of the keypad.

At least that is where it is on our Mori SL20 with Fanuc 10T.

Since it is 2-Axis Lathe so there is only XZ plane by default.You can not change/choose any other plane.Programming shold be like below.

N100 G95 G97 S800 F 0.1 M03
N110 G00 X0.0 Z2.0
N120 G83 X0.0 Z-85.6 R5.0 Q10.0 K01 F0.08 S700
N130 G80
In a 2-Axis lathe drilling can be done at hte cetre of Job only hense value for X is always Zero.
Z :- Depth of hole
Q :- Packing Depth
K :- No. of repeat
F :- feed in mm/rev.
S :- R P M

I agree with premier industr.

10T is usually set up with no G81-G86, because those are mill cycles. G74 is your only choice, and not a great one at that. It pecks (G74, either one or two line command), but doesn't retract fully each peck. Macro for that.

Thanks for the replys, this machine has a G83 cycle but you have to change to a G17 plane to use it, I dont like to change planes on a 2 axis lathe, maybe some one turned on a option? it even shows it in the setting page, you know were you can change the return amount in the G83 cycle. anyway im going to use a macro for the drilling, Ill look for the ID/OD button on the key pad. thanks again

On a mill I used to run, G83 had a parameter for "Z is only drilling axis" or "all axes may be drilling axes. Don't know if your control covers this, but I'd check it out.
