Okuma Lathe Work Offsets

[dan m]

I have been running an Okuma cadet lathe with a osp700L control on it and i can figure out how to shift all my tool offsets at 1 time like u can on a fanuc using either g54 or the common work offset. I would appreciate any help.

Thanks

Dan

simply add this line to shift the work offset

 

G91

G50Z.125 (shift value)

G90

 

 

 

the reset button will bring back the offset at it's original value

Thanks for the quick reply that worked perfect

Or use the variable

 

VZSHZ Z-axis origin shift

[Data range] -99999.999 to 99999.999

[Example use] VZSHZ = 200.000

 

This will move the Z zero 200. When M02 is read or reset in pushed the value will be forgotton

Hey Greg, how do you restart in the middle of a program on an OSP5020L? (Same machine) Say a program has 5 tools, and I just want to start at the second or third tool.

If you want to shift them for the job, go to zero set in Z and Add, -.125, Write

Joe,

 

In Auto: Extend, Restart, N1234, Write

 

At this point the machine will begin to "run" the program in its mind, as you'll see by the cursor moving. When the cursor stops (make sure you are in single block with the feedrate override turned all the way down) push the Sequence Restart button (should have a little ridge around the edges). The turret may index and the machine will want to move to where it "should" be, so be alert at this point. Once you get where you're going, push Cycle Start and you're good to go.

 

I think there's also a Number Search button that may work like a Fanuc, but we NEVER use it

to use the Nsearch restart, you got to push the interlock and the start

 

but this can be dangerous because the control don't see the tool length value

Chris,

I tried shifting it on the zero set page and nothing happened that what prompted this post. When I entered the number in the zero shift colum and left the page it went back to zero

Dan, I have never used the Shift column (we write to the WOFS Z in every program (VZOFZ=V182+V183+POFP+V1) and use Common Variable #1 as a shift value, but that is more complicated than what you asked for) but on the Zero Offset line, go to the Z column and Add, -.125, Write

Thanks Chris i will give that a try

[Greg Williams]

Restart it with Chris' instuctions

'Nother question for you Okuma guys: Where is the spindle load meter on the OSP5020L.

[chris m]

That's one I don't know; we don't do heavy enough machining on our 5020 lathes to care.

Go on the "actual position" page then press page up to get to the spidle/axis load page

Thanks Goldorak!
