I am a fanuc guy that lost my job and now I am in another shop and they just bought an Okuma MC50VA Mill with an OSP7000M control and said learn it. I am looking to do a simple circular interpolation. I would like to spiral out from my tool size to my hole Dia Are there any g codes to do this on this control?

Thanks

Try this for XY plane
G15 H1
Z100 G56 H1
X0 Y0 S100 M3 F1000
Z-20
G1 G41 X20 Y0 D1
COPY Q10
G91 G3 I-20 Z2
COPYE
G90 G0 G40 X0 Y0
Z100
M2
this makes each circle radius increase by I=20 and each step deeper by Z2. Not sure, if Z-2. Here are Q=10 steps of cycle.

Thank you I will give this a shot. I have another question, Say I have a thru hole and I want to make it .020 bigger using circular interp. I did this on the HAAS I used to run I would use G13 I.25 K.26 Q.002 D1 F20. this would make a .520 from a .5 drilled hole

OK I got an alarm #2268-03 Alarm B plus travel limit over Z- Axis 2 I believe that it was in the COPYE line. also I get the copy Q 10 but what is the COPYE

THANKS FOR TAKING THE TIME TO HELP ME

G13 on a "Haas" is for pocketing, why are you not using G3? If you are making a hole .02" bigger thats .01 per side of the tool, it could be accomplished much easier with G2 or 3.

G13 was only one line and very easy, the I was for the start of the hole and the k is for the finish dia Q is for the depth of cut this is very simple and I used it many times on the HAAS this is why, and I never used it for pocketing I used G13 for holes all of the time and it worked GREAT But this Okuma is different and I am trying to figure it out

Thank you

That's cool, if that's the way you learned it. But that's my point, Okuma is not Haas, you can do the same thing on an "Okuma", "Fanuc", "Mazak", "Citizen" or anything else, you can universally use G2 or 3. G13 and 12 are designated for starting at a center and spiraling out, and stepping down. If you are just opening up a .25 deep hole x .02, there are much, much, much easier ways to do it.

G1 X.01
G3 X-.01 R.01
X.01 R.01

Positioning is the same, you don't need to command INC and ABS, and you certainly don't need to go that slow.

OK so I may not have explained my self very well spiraling out is what I am trying to do and you are right this is not a HAAS. So can I spiral out on this Okuma OSP7000M say from a 1.0 hole to a 1.5 Dia? I am trying to read this book on this machine and it is way different. So thank you for your help.


Again thank you
