In this episode of our "Tip-of-the-Day" series, Mark Terryberry (resident CNC Guru) walks us through how to shorten tapping cycles dramatically, by speeding up tap retract speeds.

Follow along with Mark as he shows us how easy it is to speed up your tap retract cycles. At the Haas control, Mark breaks down step-by-step how Setting 130 works, and explains what it can do for you.
This video explains how to use Haas setting 130, the tap retract multiplier, to reduce cycle times. By increasing the retraction speed of the tap relative to the feed-in rate, machinists can significantly save time per part without affecting the quality of the cut, as the material is already removed during the initial descent.
Welcome to the Haas Tip of the Day, where we cover the topics that every Haas machinist
needs to know.
My name is Mark, and today we're going to show you how you can save time by doing almost
nothing, just changing a setting.
Let's talk about our setting 130, Haas's tap retract multiplier.
To explain this, we're going to go to the whiteboard.
Now today, I'm cutting on a piece of steel with a quarter-twenty tap.
At 600 RPMs, we're going 30 inches per minute.
Now, with setting 130 set to a 1, we're going to retract at 1 times my feed-in rate, which
is 30.
Now, if we change setting 130 to, let's say, 4, then we're still going to feed in at my
program 30 inches per minute.
But on the way out, we're going to go 4 times faster.
The steel's already been cut on the way in.
We just need to get the tap out fast.
So we're going to retract at about 120 inches per minute, and that's a lot of time saved.
Let's take a look at our setting 130.
To find out what the machine is running at, we'll press the setting button.
We'll type in 130 and press the down arrow button to search, which shows us our 130 tap
retract speed.
Now, it is set to 1.
Now, setting 130 will accept any value between 0 and 9.
We've chosen 4 because it's a good place to start for most of our tapping applications.
If you've got a long tap, you might benefit by going higher.
You'll need to experiment.
Now, if I change that 1 to a 4, retracting at 4 times the speed, I can save 13 seconds
per part.
That's more than 3 hours in a month.
That's a lot of time.
We're going to run this tap for you in slow motion.
On the left side of your screen, you're going to see it running at normal speed.
On the right side of your screen, you're going to see it retracting at 4 times its normal
speed with a value of setting 130 set to 4.
Now, we're tapping this hole, and you can see running this in slow motion that the right
side of your screen is going way faster with a setting 130 value of 4.
This is huge.
This is a big time saving.
Why isn't everyone using setting 130?
Setting 130 affects all of our tapping cycles globally.
It sets a default for everything.
Now, we can add a value, a J value, to our G84 tapping line, J1, Enter.
That's going to force this particular tapping cycle to retract at 1 times the normal speed.
If I'd used a J2, it would have gone to 2 times the normal speed.
Whatever J value I put on my tapping line overrides the global effect of setting 130
for our tapping cycles.
Now, all Haas mills, with mill version 10.18 and newer, have this feature as long as you
have the rigid tapping option enabled.
Not only that, but even on our BF6 with a powerful 50 taper spindle, you can still use
setting 130 to retract this tap at much faster than it's feeding in.
As you can see, setting 130 can be a huge time saver.
Be sure to check your setting 130 to get the most out of your Haas machine.
