Hi everyone,

We just bought an old FANUC control CNC MILL of which has G13 AND G12. One of the problem is it has limited of memory, we have to make quite lots of holes and is there away we can shorten the GCODEs in the CIRCLE MILL to G13 or G12?

 

This would be nice if we can do that so it can fit into any equipment because nearly ALL of the FANUC can run G13 and G12 to make perfect holes.

 

 

 

Thank you for helping.

I know this doesn't answer your question, but if you're limited on space, you can use macros. We use a bunch of different macro for things like that and I use MasterCams custom drilling cycles to programs.

 

For example this line " G65 P9996 Z-1.0 R.1 D.75 T.375 Q.05 F20. " would helical bore a hole. The arguements tell the macro, depth, tool diameter, feed, rapid plane, etc.

 

And here is the macro in the machine.

 

O9996( G65 P9996 Z R D T Q F S-W/OPT. ) ( Z = #26-FINAL Z DEPTH ) ( R = #18-RAPID PLANE ) ( D = #7-FINISH DIAMETER OF HOLE ) ( Q = #17-Z DEPTH PER DIAMETER ) ( T = #20-TOOL DIAMETER ) ( F = #9-FEEDRATE ) ( S = #19-SPRING PASSES ) ( W = #23-FEEDRATE OVERRIDE 0=OFF/1=ON ) IF[[#20*#7*#9*#17]EQ0]GOTO990 #104=#[13000+#4107] #100=#5003 #101=#5001 #102=[[#7-#20]/2]-#104( CALC. SWING ) #103=#26+[#17*2] #149=#19 #119=#9 IF[[#23*1]EQ0]GOTO20 #135=[#102*2]*3.14 #136=[[#102*2]+#20]*3.14 #137=#135/#136 #119=#9*#137 N20 G0G90Z#18 G91 G1G41X#102F#119 IF[#26GT#18]GOTO30 WHILE[#5003GT#103]DO1 G3I-#102Z-#17 END1 GOTO40 N30 #103=#26-[#17*2] WHILE[#5003LT#103]DO1 G3I-#102Z#17 END1 N40 G90 G03I-#102Z#26 I-#102 F[#119/2] WHILE[[#149*1]GT0]DO1 G03I-#102 #149=#149-1.

I believe we don't have this macro inside the parameter yet I think we have to call cnc service man to load this up. On the other hand, I would like the G13 of which works for most of FANUC control. Thank you, Ray D.

The macro is actually something we wrote and added to our machines.

 

The G13, we don't use here so I can't help you with that. But I'm sure someone here on this forum will have some ideas for you.

 

Good luck.

Using G12/G13 is very similar to inputting info for a macro, you just define the parameters of the cut

 

Consider using a customer drill cycle to achieve this

 

There is a TON of info on this forum about custom drill cycles ifyou use the search, I seem to remember some years back someone else wanting add this as well

 

Just remember, all you're going to be providing is the info for the cycle, Mastercam will not show you that path as a backplot or verify

Dear colleagues.

Is it really so big problem to answer to this question in more detail? For example I have been looking for this answer for long time and cannot find.

No, but not so simple.

BUT I see a way to solve it. For example if you program a Circle Mill OP in MCAM, you can post it as G65 Pxxxx instead of G2/G3.

So yes, it can be solved by posting out a macro call (or G12/G13 on HAAS). I made some similar in the past and some macros combined into NC code by post, so it's possible for sure.

BUT this takes time and...
