Lathe Canned Drilling Cycles - Post Help

[Tim Simmermon]

After a few years of hand coding canned drill cycles for my lathe, I decide to research into changing my post.

 

Through a forum search I added this to my post:

 

quote:

---

lpeck$ #Canned peck drill cycle, lathe

pdrlcommonb

pcan1, pbld, n, *sg81_f, prdrlout, pfzout, *peck1$, pffr, strcantext, e$

if initht <> refht, pbld, n, sg00, initht_z, e$

pcom_movea

This is my output:

I need the Q value to read as Q1000

 

I am running Fanuc 21i control.

 

I know it is a format change, but I can't remember how to change a format to post with no decimal.

 

Also, with the lathe peck cycle is there a way for it to post without the Q value if I leave it at 0. It would be nice to give the operator the opportunity to add the peck if he feels necessary.

 

I read in the Fanuc book that if the Q value is absent it still drills with no peck.

 

Thanks for the help.

change

 

code:

---

fmt  Q  2   peck1$       #First peck increment (positive)

---

to

code:

---

fmt  Q  7   peck1$       #First peck increment (positive)

John,

 

That removed the decimal and gave me this

 

G83 R.145 Z-1.75 Q0000 F4.2442

 

I triple checked the parameters and I entered .1 into both the initial and subsequent peck depths.

 

Any ideas on what I could be missing?

Tim, my bad

 

try changing it to a 16 instead of the 7

[Randy Morton @ Clem Industrial]

The alternative is add a multiplier to the variable

 

code:

---

peck1$ = peck1$ * 10000

Thanks guys,

 

I'll try it on Monday.

John,

 

Changing it to 16 worked perfect, thanks!
