Hi all,
I am needing help programing okuma lathe with osp p200 control

I want to machine 5 pieces out of bar stock, looping back to the start, run 5 pieces ,then stop so I can reload it. I use a puller, I have used the goto to loop back to the start. Just need to count parts.

thanks, paul

I've used a 5020 control but never a p200, so this might not work.

On the 5020 you can use variables & conditional branching.
IIRC this is how you would assign a value to variable 1:
[V1] = 1

Adding to variable 1:
[V1] = [V1] +1

So you need to add [V1] = 1 above the line you're looping back to.
Add [V1] = [V1] +1 above the line that loops back.
Then edit the loop back line to a conditional branch that will only loop back when [V1] is less than 6.

Just to expand on Ted's suggestion for a generic program

HEADER, COMMENTS etc.
V1=0...set count to zero at start of run
N1... safety code line G0 G40 etc
...
your PROGRAM
....
V1 = V1+1....advance count for completed part
IF V1=5 NEND.....if count hits this number, jump to line NEND
GOTO N1.....jump to N1 line
NEND M30
%

I had to replace (=) with (EQ) in the (IF) line with brackets
then it worked great. thanks for the help!
