I was looking for advice for okuma mc4vae (with 4 axis), what kind of software do you use? is the post processor good? thank you

[maxlopez]

hi, does anyone use cadcam for this old mill? thanks

[Superman]

It's a very restricted machine... slow rapids, slow toolchanges, not a high RPM spindle. It really is old tech.

OK, it is the extended bed version, so it'll take a 4th axis on R/H side
I hope you have lots of file space, as it is needed if using code from a CAM system.

Check also that you can do a 3 axis arc move. The one I used could not.

Is the machine DNC equipped?

[maxlopez]

not have dnc..
have "tape storage 320m"
"one part program capacity 160m"
"additional axis A"

[Algirdas]

So, the final part program can be 60kB big.

[maxlopez]

I have to try if it performs the 3-axis arc movement, it's exactly as you say.., thanks

[Algirdas]

if it performs the 3-axis arc movement

the check itself is not related to the part program size. MDI mode
G91 G01 Z5 X5 Y5 F0.1 ; for instance gives you the answer instantly

Also, you can check your OSP Data Management Card. If the "Helical cutting" is marked there?

That is NOT an arc, that's a linear move

[Algirdas]

it's possible to make an arc composed from many small straight segmets. Here the memory capacity comes to play the role.

the helical cut is present :-)

Hi, max
I have tried allot of cam software for my Okuma MC5 VA and came to conclusion that feature cam by autodesk works the best for me.
I don’t know if the fusion 360 extension gives the same results as it is basically the same thing. But as I said I prefer feature cam

[Voss_Machine]

I had a 4VAE...used Surfcam on it. That machine is a beast, two speed geared head, box ways.....messy though has it isn't enclosed.
