G71 Fanuc 21iT D;R value problems

Recommended Posts

Hi,

 

I have been given the task to modify the post processor here at work. I have been able to modify it to the old style 

of canned cycles in G71. But it turns out I have a problem with the D and R values. the machine (a doosan puma c250 ) for what 

ever reason, only takes microns as value.

 

this is the code I currently get:

 

G71 P20 Q30 U.4 W.2 D1.5 R.2 F.35

 

and this is the code i would like to get:

G71 P20 Q30 U.4 W.2 D1500 R200 F.35

 

thanks for the help

 

cheers 

Alex

Hi Alex,

You need the change the formatting for D and R in the post, your dealer can help with that, its a quick fix

thanks Greg  for the quick info but unfortunately we do not have an active service with mastercam.

is there a way I could do that in the post?

You need to give the variable a new format address.

Assign new format statement. Assigns the format statement n to variable x, replacing the existing assignment. Returns 1 if successful.

result = newfs(n, x)

Example: 
In this example post block you would reformat  depthcc, and  clearcc to format statement 25 (fs2 25   0 3 0 2t     #Integer absolute, 4/3 place)  
 
pg71old         #Output G71-G72 canned cycle routines, old style
      result = newfs(25, depthcc) #D Value reformatted to fs2 25
      result = newfs(25, clearcc)   #R Value reformatted to  fs2 25

This sounds suspiciously like you do not have a legal Mastercam license.

we do have a legal Mastercam license but the service license is up to date. I have always been under the impression

that you have to have a active service license in order to get work done on the post.

Nope any dealer will work on a post, but it may or may not cost you depending on the modification and relationship with the dealer.
