Check if Rough or Skim Pass

[CNCGUY]

Hey guys,

 

Is there a way to tell the difference between rough and skim passes? Rough pass needs M37 and skim pass need M38.

 

I could do it with misc. int., but there must be another way!!!!

If you have one Rough and then the Finish passes in the same operation, then Yes.

 

There is the post variable pass$ which will tell you which pass (count) you are on in the operation.

 

code:

---

ptlchg1002$      #Call at actual toolchange, 

 

"(PASS = ", ~pass$, ")", e$ # Current PASS

---

So you could key off an "if pass$ = value" test and output code based on the result.

troy, put this in your post. hth

 

 

psof$ #Start of file for non-zero tool number

!op_id$

pcuttype

g20code$ = zero

cc_pos$ = zero

prv_xia = vequ(startx$)

prv_uia = vequ(startx$)

*progno$, e$

comment$

pbld, n$, *sg20code, *sgabsinc, [if feed_out, "G94"], e$

pbld, n$, "M31", e$

pbld, n$, "G77 P1", e$

if tool_op$ = 74 & contour_typ$ <> 0, n$, "M15 P1", e$

if tool_op$ = 74 & contour_typ$ = 0, n$, "M15 P0", e$

if strtflag = one, ptlch_strt

else,

[

prv_g20code$ = -1

prv_xabs = c9k

prv_yabs = c9k

ptlch_nstrt

]

if skimpass$ > -1,pbld, n$, "M37", e$

else, pbld, n$, "M38", e$

# if skimpass < 0, pbld, n, "M38", e$

pbld, n$, pconchg$, e$

motst$ = one

sof = zero

Thanks guys, I'll give it a shot.

is this a fanuc wire post

[CNCGUY]

O.K., we're closer.

 

Roger,

 

Typically rough and finish are differnet passes.

 

 

Del,

 

With your code, the first skim pass still post M37

Del,

 

Guess I need to dig a little deeper!!! Do you have similar code in ptlchg$ as well?????

 

 

Roger,

 

Yes, this is fanuc wire post!!! Comments???

[Guest]

yes i do.oops!

 

ptlchg$ #Tool change

pcuttype

 

g20code$ = zero

comment$

!xabs, !yabs

if op_id$ <> prv_op_id$, sg20code, xabs, yabs,e$

 

#if there was no motion, stop gcode, else force motion

if (motst$ < one | motst$ > 7) & not(strtflag), !g20code$

else,

[

prv_g20code$ = -1

prv_xabs = c9k

prv_yabs = c9k

]

if strtflag, ptlch_strt

else, ptlch_nstrt

if skimpass$ > -1,pbld, n$, "M37", e$

else, pbld, n$, "M38", e$

# if skimpass$ < 0, pbld, n$, "M38", e

pbld, n$, pconchg$, e$

!op_id$

O.K., I have determined why the M38 does not work on the second pass - Its not the same geo as the first pass. I need to figure out some logic to do this one!!!

 

Since we draw lead in/out lines, is there any way to "force" Mcam to cancel cc on the last move rather then have an extra .01 move?

 

Hope this makes sense.

[Guest]

troy, you don't have to create your own leadin-out geometry anymore. use your thread and cut icons.it should cancel the comp after it leaves the geometry on your last move.do you have line lead in and out checked in the control def.under start/leads.is it posting correctly or not doing right at the machine.look at your post and find pccomp and see where it is at.

Del,

 

Looks like I have some more work to do.

 

The new features are neat, now I just need to figure out the best way to make all of this work for US .
