Is there a way to loop a program to cut 20 flutes
around the od of a part 18 degrees apart with
just the toolpath of one flute. On a mazak we use
a program that looks like this.

(H11 MEANS RUN FROM N11)
M98H11L20 (L20 MEANS REPEAT 20 TIMES)


G91G68X.0Y.0R18. (ROTATION FOR 20 V-CUTS EX. 360/20)
M99P12

This cuts 20 flutes every 18 degrees apart. Then the
program ends.I see where you can use L101 on a fadal,
but don't know how to make it count for the 20 seperate
cuts, then end.
Any help would be appreciated

It is a lot more complicated than I want to try to explain

If you PM me your e-mail I can scan and e-mail you some pages from the users manual

Here are a couple sections from the manual.

HTH,

The repeat for the sub is in the call out--
L0101 calls sub L1 1 time
L0120 calls sub L1 20 times.
Your program could look something like this-
O001
L0100*
G1 X.
Z-
.
G0Z1.
G0G91A18.
G90
M17*THIS CODE IS FOR END OF SUB PROGRAM
M30*THIS IS FOR END OF ALL SUBS
M6T1
G0G90M3S1200
X- Y-
Z.
L0120
X0Y0Z0E0H0
M2
%

Fadal also allows you to call out different programs Fanuc style via M98 and
M99
Hope this helps!

Libbey,

If you need any more pages let me know.
I am not at work today, but I could go in

Also G68 might be an option on the Fadal I don’t know for sure

Techman,

That is what I originally thought too but he is trying to use a G68,
which is a coordinate rotation not a rotary table.

FUN4ME-
My mistake! That is just like me. Always trying to over simplify.

Libby,
The Fadal will accept a G68
The format is: G68 R0+18. X0 Y0
I don't know if the R variable can be an incremental number or not. If so, then the G68 line could be inserted into the sub- program. If not, then the R value would have to be incremented either by a macro statement or set each time the sub was called out.
Hope you find this helpfull!

Thanks guys for all the good advice. Our machine is currently
tied up on another job, but when it's open I will try this info
and let ya'll know how it turns out. This could help solve
alot of our memory problems.

Finally found a way to do it. Couldn't figure out the L101. Got it
to loop, but wouldn't calculate changing angle. I Did it as a macro.
I wrote it to make 4 cuts 90 degrees apart, then end. Changed 90
degrees to 20 degrees and it worked perfect. I've attached it if
anyone thinks it may be useful for them. I cut out most of the
program to shorten it, but you get the picture.

Thanks again for the help

Libbey
