Post output of G83

[Joels]

Hello I have done a search and could not find the awnser but can someone tell me how to get a G83 for peck drilling on a fanuc post fot a old haas lathe?

[crazy^millman]

What post are you using? What version of Mastercam?

[Joels]

I am using 9.1 and the standard fanuc post

How old? What controller? I have old Fanuc controllers here that will not reackonise a G83.

In the drilling toopath select Peck as type of Cycle for drilling

If your controller ends up not being able to recognize a G83 commmand there is still an option of a macro.

 

This was posted by Saipem and may work for your needs.

We have a old HAAS lathe that is 10-12 years old. we use G83 all the time and we just alter the machine code in the control but this is getting old so i would like to alter the post to get a G83 everytime we select peck from the options.

The link looks great but will that work on a version 9 post?

[Guest]

Sure it will work in a V9 post.

 

The macro would reside in your control and you would set up a custom drill cycle with the parametres you needed to define. Fill in the correct info in the boxes and your drill cycle would then be complete.

 

There is a ton of good information about custom drill cycles if you do a search

Look in the post for this section;

 

 

code:

---

 pcuttypldrl   #Change cut parameters for lathe drill

usecandrill = 0

usecanpeck = 0

usecanchip = 1

usecantap = 1

usecanbore1 = 0

usecanbore2 = 0

usecanmisc1 = 0

usecanmisc2 = 0

---

You'll want to change the usecannedpeck : no (0) to usecannedpeck : yes (1)

i saw that and changed it but i still dont get the G83. My employer will not let me change the machine as they are still in the stone ages (lather 10+ years old). I will ry the post mod for the ver x post and see what happens. Thank you for your help.

I haven't touched a lathe in a while but I think there is an option in lathe toolpath parameter page (drilling) for long hand and canned cycle...

I can get the long version of the tool path for a peck drill and it works well but it can take alot of memory to store the program.

[crazy^millman]

Ok so then if you are getting the long version you should be able to get the short version. What happend when you change the variables to make it short canned cycles code like metioned above here:

code:

---

pcuttypldrl   #Change cut parameters for lathe drill

usecandrill = 0

usecanpeck = 1

usecanchip = 1

usecantap = 1

usecanbore1 = 0

usecanbore2 = 0

usecanmisc1 = 0

usecanmisc2 = 0

---

Do you get a change in the code if not then do you have this set correct in MPFAN:

code:

---

mdrl_dir    : 0     #Mill drill direction for boolean, 0 = face, 1 = cross  

---

My thinking is if his got change for some reason it might make the post go screwy should not but I would make sure everything is like it should be. Might even try pulling a fresh copy off of the CD and going from there to make sure all is ok.
