Ok...here is my issue. I need to use a bar puller and I am too green to know how to make the turret move without the spindle rotating. I do obviously use G00 for rapid positioning, but I need a slow and deliberate movement when using the bar puller. What code do I use??? Thanks.

I don't know if the Okuma uses different G-Codes but this is how I program a a bar pull when I have a X-Axis puller.

N100T1200(CALL TOOL)
GOG97M5(SHUT OFF SPINDLE)
X1.0Z1.0(APPROACH BAR)
Z-1.0(MOVE DOWN TO PULL AREA)
G98X0F50.0(FEEDS DOWN TO BAR G98 ALLOWS MOVEMENT WITHOUT SPINDLE TURNING)
M69(OPEN CHUCK USE THE APPROPRIATE CODE)
G01W1.0(PULL THE LENGTH NEEDED TO MAKE THE PART = CU-OFF WIDTH)
M68(CLOSE CHUCK USE THE APPROPRIATE CODE)
G1X1.0F50.0(MOVE OFF BAR)G0G99X(HOME)Z(HOME)
M01

That makes perfect sense to me...and I have been looking for an Okuma Equivalent of your G98...but I dont have that in my book. I assume there is no G98 for Okumas, so their equivalent is what I am looking for.

WGJ,
Use G94 for inches per minute. This allows you to move the turret without spindle rotation. (G94X0.0Z1.1T0101F75.0)

Thanks buddy. I hate to tell on myself, but I just stumbled across that in my book. I was 30 seconds from posting my findings. This was one of those proverbial "haven't gone down that road yet" deals. Thanks.

Just a follow up...as of today I am now using a coolant actuated bar puller and rather than 'one at a timing' the parts I can run bar stock in 48" lengths. For this particular part, I am running 18 parts back to back; which equates to 1.5 hours of unmanned machining. Thanks to all who helped.
