Another Okuma Canned Cycle

[matt890]

Hey guys I have another one. I am trying to add a G80 to the end of my G85 (G71 in Fanuc land) Canned cycle. For the life of me I am unable to find out where to place the code. I contacted my reseller who told me to put it on the ng70s, ng70e line under pread_g70. That does not work. 
 
This is what I am currently outputting:

(***************************************************)
NS1(TOOL - 7 OFFSET - 7)
(CHAMBER OD FINISH  INSERT - VCMT-331-SM)
G0 TG=7 OG=1
G97 S2339 M03
G0 G54 X.98 Z0. M8
G50 S3600
G96 S600
G85 NRUF29 U.1 F.004 U.02 W.01
NRUF29 G81
G0 X.7225 S600
G1 Z-.0092
X.8033 Z-.0496
G3 X.8125 Z-.0606 L.0156
G1 Z-.4731
G3 X.8059 Z-.4828 L.0156
G1 X.7275 Z-.5329
Z-.6046
G2 X.7583 Z-.62 L.0154
G1 G40 X.98
G0 Z0.
M9
G0 X40. M05
GOTO NEND
(***************************************************)

What I need is this:

(***************************************************)
NS1(TOOL - 7 OFFSET - 7)
(CHAMBER OD FINISH  INSERT - VCMT-331-SM)
G0 TG=7 OG=1
G97 S2339 M03

G50 S3600

What post processor are you using?

[matt890]

The base is the generic fanuc, but I have already modified a lot of it to output what I need. I basically just need to figure out the LAP cycles then it will be done.

[Mick]

There was an Okuma post that was part of the post installation executable, that had the LAP cycles all defined. It seemed to work pretty well from memory.

 

Seems to me that would have been a better option, rather than converting a Fanuc post.

 

Maybe use the variable lathecc to (if lathecc <> 0, "G80")

 

Without knowing the post, I wouldn't be sure where to put it though.

[matt890]

I gave that a whirl, but still cannot find the correct place to put that. It is either placing the G80 at the top of the sequence or after every line in the sequence. 

 

Edit:

Got it to work by adding a "G80" line here:

        #Write the cycle profile, sequence are written now
        rc3 = one
        while rc3 <= size3,
          [
          #Write the lathe canned cycle profile
          string3 = rbuf (three, rc3)
          if rc3 = two,
            [
            #Add the finish spindle speed to the first move
            speed = n1_ss
            pbld, *string3, *speed, e$
            ]
          else,
            [
            if omitseq$ = one & rc3 = size3 + one, pbld, *string3, e$
            else, pbld, *string3, e$
            ]
          ]
		  pbld, "G80", e$
        #Close the buffer
        result = fclose (three)
        #Remove the ext file
        result = remove (sbufname3$)
        ]
