Title pretty much says it.
Is there a programmable rapid override on Haas'?
I would like to implement this on certain cycles on our machines and would like to know if there is a command to lock out or override the rapid traverse function on Haas'?

[Edster]

There's a setting that limits the rapid override to 50%

Don't think there is a way to program it but I might be wrong.

Setting 10 - Limit Rapid at 50%
Turning this setting On will limit the machine to 50% of its fastest non-cutting axis motion (rapids). This means, if the machine can position the axes at 700 inches per minute (ipm), it will be limited to 350 ipm when this setting is On. The control will display a 50% rapid override message, when this setting is on. When it is Off, the highest rapid speed of 100% is available.

I do not think this setting is changeable in the program.

Try using minute pitch.

Thank you all for the replies, I will look in the programming manual and see if there is a way to call up Setting 10 and release it after a tool cycle. Every model machine has its own little quirks so, who knows. The reason is I like to run all of my threading cycles at 25% rapid traverse, I know this may seem like a "no-no" or "pointless" but it is what it is. I don't know what "minute pinch" is can you elaborate andre 77?
The machine in particular is a tl-15, I'm not really a Haas fan but this little machine actually holds reasonably well for its power and size. With a "full" C-axis and sub spindle I'm looking forward to getting the company recently started working for actually USE the machine to its full potential

Sorry for the inaccurate translation, I do not speak English, I use a computer program to translate.
You can try to replace G0 G1G98F (G98 Feed Per Minute), but in your case it does not help, you want to change the high speed with G76.
You need to write a loop like the G76.
Program code should be something like(program uses millimeters, 50 millimeters approximately equal to 2 inches).

G0X56.Z6.
M97 P1000 L7

.
M30

N1000
G99
G0 U-6.3
G32 Z-75. F1.5
G0 U6.
G1 G98 Z6. F6000. (6000/25.4=236 inches Per Minute)
G99
M99

I was basically trying to program the machine to slow down the actual rapid/traverse in one tool cycle (threading only). The program I'm using is in fact a basic G76 (only in this case turning an angled thread with an angled holder I was just trying to get the machine to stay in 25% rapid traverse on the thread only cycle to allow the screws to get straight and the insert to cool down. It's not programmable so I just change the inserts sooner, they're not really meant for 303ss but meh...the shop wants "universal" everything, so it is what it is. Thanks!

Program a longer thread lead in. That will buy you some time.

Would changing the "approach" work that way with an axial thread?
