is there a way to increase the retract rate in a tapping cycle?
on the Haas I used to run there was a parameter for this, the value entered was a multiplier, so If 2 was entered, the retract speed would be twice as fast
thanks for any help,
Kenny

Depends on which control your machine has
Which is ?????
I know the OSP E100 has fast retract, maybe the E10 as well, P200-- yes,
the 7000s and earier would not have it
Best to check with Okuma for final comfirmation. or your Data Card in the back of the machine
then if you have, then you can work out what parameters need setting to enable the function
Don't remember details. I'm sure, we use taping with fast retract on exhibitions. OSP U100M. I didn't knew, that could be problem with retract speed.
Check what taping cycle You use.
sorry, its osp u700m and osp u100m machines
and we use G284 cycle for tapping with a solid holder
U700M .... you sure ??? not a 700M or 7000M .... the last 2 ... pretty sure they do NOT have fast return tapping
OSP U100M .... yes, it does have fast un-threading, it has to be enabled in the parameters , no change to the program at all, I think you can also have sync. tapping happening on G84 as well.
Not at work, so I can't look up the numbers for you, sorry.......someone else ???
OK I probably got the U700M wrong
I'm at home with the U100M book next to me and I thought the other machine model read the same way
It must be a 700M, I know its not a 7000M
Thanks for setting me straight
The book I have for the U100M is the programming manual and it doesn't cover the parameters but I'll have access to all the books monday at work.
I appreciate the help - now I know where to look.

Instead of using the book, why not use the disk, it has all the books in PDF form
Hard to remember, but I copied the section that has a "START.PDF" or similar to a folder on the PC hard drive, deleted the japanese stuff, sent a shortcut link to desktop from the START.PDF file and bingo you're away.
No, it not in the programming manual, maybe special functions #1 or #2
PS just gone to 2010 here, so happy new year
Thanks Supe,
I'll inquire about the disk monday
happy 2010 down under
I found the parameter, but it didnt work
I set it to 200% but there was no difference in the cycle time for 24 holes tapped .700 deep
could there be another setting or parameter canceling this out?
I also changed G84 to synchronous tapping with bit parameter #17
I also hit the "backup" after the changes
I didnt have much time on the machine today, tomorrow I want to watch closely the actual RPM and see what its topping out at.
Tapping rate is S600 F30.
Dont you think it would be able to reach 1200RPM as it travels from Z-.7 to R.1?
Hi,
Will spindle go from 600 to 1200rpm without having to change gear?
If current gear maxes at 600rpm maybe that will override the retract rate.
DP
Maintenance says there's no gears, but a low/hi range output by the spindle motor, I didn't find out what those ranges are yet
I re-set the parameter to 100% and watched the actual rpm in cycle, it topped out right at 600 with time to spare
When I set it back to 200%, the retract rpm topped out at 630
same thing when I set it to 150%
Try setting aN RPM above 630 and let the G-code start the spindle
then play with the retract speeds
Code:G0 X0 Y0 S750 G56 H1 Z1. G71 Z1. G95 G284 Z-1. R0.5 F0.04 M53 ( pitch for a M6 tap ) X1. Y0. X1. Y1. X0. Y1. G80 G94 M5 M9 G30 P1
"Maintenance says there's no gears, but a low/hi range output by the spindle motor"
Not quiet. There are 2 sets of windings in the motor. To change range the spindle must stop
Try tapping starting at 650 RPM or an RPM high enough to put you in second "gear". Then you shouldn't top out as easily. I know tap size may limit your desired speed, so if need be back off on your z offset and try it in the air to see if it works.
You should be able to find your machine's operating range in your Operation & Maintenance manual - different machines have different range limititations, but the machine will not "shift" during a tapping cycle - that may be your problem.
Best regards,
There are 2 sets of windings in the motor. To change range the spindle must stop
are You sure? There is no need to stop the spindle for eletrical gear shift
the machine will not "shift" during a tapping cycle
easy to try with lower feederate. It would be even easier to see, if retract feederate is different
Thanks guys, I set the RPM to 650 and it came out at 1300
Now I'm tapping at 1000 and coming out at 2000, it saved me 45 seconds per cycle
cheers :cheers:
