I want to add a G73 to my Postform for a fadal. This is how I edited it:

WorkDefault 1 # Work offset register default

Drill # Drilling canned/manual cycle
G81 R[Vclear] z[D] F[FRate] X[H] Y[V]
end cancel

Chip Break # Chip Break canned/manual cycle
G73 X[H] Y[V] Z[D] Q[VBite] P[DWELL] R[Vclear] F[FRate]
end cancel

Peck # Pecking canned/manual cycle
G83 R[Vclear] z[D] F[FRate] Q[VBite] X[H] Y[V]
end cancel

LTap # Left handed tapping cycle
G74 R[Vclear] z[D] F[Frate] Q[VBite] X[H] Y[V]
end cancel

Tap # Tapping canned/manual cycle

G84.2
G84.1 R[Vclear] z[D] F[Frate] X[H] Y[V] S[Speed] M3
end cancel

Ream # Reaming canned/manual cycle

end cancel

Bore # Boring canned/manual cycle
G86 R[Vclear] z[D] F[FRate] X[H] Y[V]
end cancel

Back # Back boring canned/manual cycle
G76 R[Vclear] z[D] F[FRate] Q[Sclear] X[H] Y[V]
end cancel

I attached a screen shot of the error I get when I run it.

thanks for any info.

Anyone?

Tmcallister,

There is not an option under NC->2 Axis->Drill called Chip Break. You can probably call it Custom1, Custom2, or Custom3, if any of them are listed on the drop down menu.

Good luck,
nick.

PS It is odd that a high speed peck option has never been part of the menu.

Yeah I know about the Chip break. It posts it out line by line, all in Z moves.
I thought if I added the G73 cycle into my post and named it Chip Break that it would use the proper code. I must have done something wrong as it just throws an error when I go to post now. I was wondering if anyone new the right way to rdit the post so that this will work. I also tried calling it the custom 1. I got the same error.

Thanks.

Hello,

This is what you need to put into your post and be sure you click on the custom1 when you do the drill cycle, let me know.

Custom1 # Chip Break canned/manual cycle
G73 X[H] Y[V] Z[D] Q[VBite] P[DWELL] R[Vclear] F[FRate]
end cancel

[tmcallister74]

That worked. Thank you very much. I was beating my head against the wall. The only thing I see different is the dwell so maybe that was it.

Hello,
in your post I think you cannot write "Chip Break" in two words in the cycle sequence. Try Chipbreak instead, it should work.

Back Bore is only named "Back" in Postform as an example, so try "Break" for G73

To use the "Chip Break" option from surfcam use the following in Mpost template.


ChipBreak
G73 X[H] Y[V] Z[D] R[RLevel] F[FRate] Q[Step]
end

FWIW the Chip Break option is present on newer versions of Surfcam, as I recall it wasn't there in Older Versions. If using the older versions you would be limited to using the Custom options as the other poster suggested.
