i use a Q value instead of adding a bunch of Z depths....fanuc control
Fantastic! I've been wondering if this was possible for a while now. I'll be using it very, very soon!
This is how I currently run peck tap cycles but I've always wonder why the G84 canned cycle cannot make use of a Q command for its peck increments? That would be a nice way to eliminate some redundant code. Thanks for the video Haas. You guys rock.
seriously!
I wondered the same thing...our VF-4 just ignores it.
Additionally our machine came from Champion Machine of Houston and no one bothered to set the 133 to on.
The people here at this shop are clueless on this.
I've got a combined 30 years playing with and programming G code machines and have issues with a supervisor with 6 months running things.
Thank you for the knowledge provided
However I use M70 Controller, it is an excellent idea which worked also on our machine. Well done Mark.
Prolive advange you use a Q value on fanuc. This is one of the few instances where fanuc control edges over Haas. On fanuc peck tapping is a single line code,very easy and also less room for human error. Hopefully Haas adapts the fanuc(and some Mitsubishi) for peck tapping.
Its nice when you check if there is a tip of the day before peck tapping without setting 133 enabled instead of after.
Really Thanks mark & Haas CNC.
A very nice feature of the G84
Thanks for this video! But what if G43 Hxx Zxxx differs from R value in cycle G99 G84 X0 Z-1. Ryyy? Will it work on HAAS with setting 133 ON?
can you use this with a G70 command? And also, can you use this with form tapping?
And when i am very much holes i can use a command from Esprit?
Thanks!

Can this be used in combination w/G70,71,72?
A word to the wise; If you put a new Z depth after your initial G84 line without a X or Y it will go to the last Z value.
Example:
T3 M6 (1/4-20 TAPRH)
G54 G17 G80 G90 G40
G00 X0. Y0. S800 M03
G43 H3 Z1. /M08
G84 Z-.2 R.2 F40.
Z-.4
Z-.6
Z-.8
Z-1.
G80
M01
^^^ THIS EXAMPLE WILL TAP TO THE LAST Z WITH NO PECK!
Example:

hello sir, I am the beginer of vmc programmer .please give me some tips for drill, boring, taping, program.

BTW. Exactly same thing with G81 if you want to have custom peck depths or to go a bit down at one feed and an bit more at another.
Just use Q in the program like
g83G54 G17 G80 G90 G40
G00 X0. Y0. S800 M03
G43 H3 Z1. /M08
G84 Z-.2 R.2 F40.Q.2

And dont need this all theese lines. imagine if u have 10 thread. u will make like this?
Great video! Is it possible to change the tapping cycle in VPS to use G84, or does that have to changed manually after outputting the code to MDI?
Excellent
wow . thank lots
Could someone please tell me if I need a special holder for any tapping operations?
Can I hold a tap within a collet on BT 40 collet holder and run the program?
I’m afraid the tap might break on the retract without a floating tap holder or what not.
Thank you so very much for your tips and advice!
Can this be used with the g70 bolt hole circle program?
We had a haas sales rep that failed to tell us about setting 133. Its been off and we have been snapping taps. Thank you so much.
Same here, I just started working for a company who bought a VF-4 a few years back and they didn't have the 133 turned on. Additionally they have used Gibbs cam which for some reason puts a G81 or G83 command in the program when you specifically pick "Tap".
The sad thing is the cell lead has never seen a CNC a year ago and is clueless on programs. He literally "drilled" the tap in the part and snapped it off.
I spent two hours arguing with him about the program being "wrong", and I guess my thirty years of programming and playing with G-code machines didn't matter.....
@@keithlucas6260he was just ahead of his time. Now you can get the combination drill thread mill.
Thought HAAS was silly when it didn't orient spindle tapping same hole. Kept purchasing Spindle Orientation on each HAAS and modified Post Process to run Spindle Orientation for every G84 command. Go figure this option can be turned on without the purchase or Spindle Orientation. Too late for 3 machines I own, but good reference for future machines.

I'm using HSM, with a generic HAAS post, and it's generate this code, the first peck is ok, start on Z5 go down to Z-3, the second and the rest, is go up to z70 and start the taping from here. Why is it not using the R5 , instead of the z70 which is the retract height, for move to each hole?
G43 Z170. H1
G0 Z70.

Thanks for your answer, and sorry for my bad english... :)
hello sir
please clear my doubt
can we use dwell time in tapping cycle please make it clear??
I run a fanuc machine and when I use g84 to peck tap the tap will only retract around 1mm and stay inside the hole rather than coming all the way out, and in my opinion I think this is what is breaking my taps, anyone have any information on this
Nice !!
How to use G70 in G84 cycle for various depths????
Does haas st10 lathe have peck tap?
Interesting way to control peck tapping. Does the setting have to be changed manually, or is there a way to program for changing the control setting on/off?
Good question!
I normally machine parts with over 100 holes and just now I am learning of that spindle orienting setting
+x19freak Setting 133 will need to be turned on in order to peck tap. The Setting cannot be changed from within a program.
How about peck tap for 10 holes. Do i need repeat like this? No canned cycle like put Q for peck like peck drill?
Sağol kral baş tacısın 👏👏
This would have helped to have known a while back when doing some stainless 316. That stuff is nasty and hated being tapped
Mark, I am curious why an X co-ordinate needs to be entered in front of the new Z depths for the G84 Peck Tap Cycle? I thought, no co-ordinates, no X,Y movement. I'm guessing it has something to do with signaling a return to R otherwise the tap would just continue down to the successive Z depths? Thank you in advance for your answer and providing these instructional videos.
+Lee Putman I'm curious about that as well. My initial thought is the extra X coordinates were for illustrative purposes. I think if they were required you'd need to enter both X and Y for each line. I think it just drives home the point that you're staying at the same position. I'd love to hear from Haas on this or maybe just have someone try it and report the results.
+Lee Putman
A word to the wise; If you put a new Z depth after your initial G84 line without a X or Y it will go to the last Z value.

+Lee Putman Hi Lee, thanks for reaching out. The control needs an XY move of some sort to trigger the cycle. If we don’t command an X, a Y, or both, it won’t tap. The Z, on each line, is to peck at a different Z depth for that pass. Good question, hope this helps!
-Mark, from the Haas Tip of the Day
Thanks Mark, I was thinking it was something like that.
Hello
The video is great. But I have a BEAUTIFUL Haas VF1 whic does not have a 'setting 133' that I could find. I still need to peck tap. Any idea on what to do?
Adel Tabsh - Setting 133 was introduced back in Mill Software Version M12.09. If your Mill is newer than that, you may need to give your local Haas Factory Outlet a call, to make sure you have the Rigid Tapping Option (Parameter 57:4 RIGID TAPPING must be on), and they can verify your Setting 133. - Mark, Haas Tip-of-the-day
Do the chips ever fall back into the hole? I often have to tap holes close to the bottom of a blind hole. Just curious if the tap ever bottoms out on the chips.
could I use this program ( without turn on setting 133 ON) ? :
G84 x0 y0 z -0.5 R0.1 F100
x0y0 z -1.
x0y0 z-0.5
.
.
.
Or :
G84 z-0.5 R0.1 F100
G80
G84 x0y0 z-1. Ro.1F100
G80
G84 x0 yo z-1.5 R0.1 F100
g80

Me gustaría videos en español gracias
Nice
I'd love to see a Tip of the Day on Lathe G76 using I for NPT Threads.
Whats your question? Its easy. I can help you
Is the repeat rigid tap feature available on all VF mills. I found the 130 feature on my VF2 mill but not 133 feature. Do they use different number for this repeat rigid tap feature? My tap broke every time if I tap deeper than 1/2 inch. I tried to tap several times on the deep holes but the tap holes got loosen on top and tighten on the bottom. I have checked the speed, feed, coolant mixture, and they're all meet the requirements. Any comments or suggestions will be appreciated.
For this issue I'd recommending reaching out to your local Haas Factory Outlet Service/Apps department; they can help you out. On older mills, (like before 2003) Repeat Rigid Tapping wasn’t a Setting, it was a Parameter. Your HFO can help you with this specific machine. Please visit bit.ly/Find_HFO if you do not know your local HFO's contact information.
Sir can u explan M29
Code.ple🙏
Mark, Does the Haas not understand the Q Value? G84 X0. Y0. Z-1.5 R0.2 Q.25 F"whatever"?
I wonder if Haas will add a Q address to the G84 cycle somewhere in the future.
Milltronics already did it
Funuc has it already
in the Bonus section there was not anything
Where to learn cnc programming plz help me
Question, in your second hole why did you input the line X1.0 Z-.5, it should read the depth from Z-.5 from the original G84 line of code right? Can you please clarify if this is not the case.
+Paulo Esquenazi The G84 command is modal and it "remembers" the last input values for each address. Thus, if you simply put a new X,Y position for hole #2 it would tap to the last Z value it was given (Z-2.5) in the line above.
can't you just add the q and the final dept.
Why do you need an X value but not a Y value?
Whats the correct feed and speed for a 1/4-20 tap ..??? Aluminum 6061
Conservatively, S400 F20. 6061 cuts easy but can gum up your tap very quickly.
Because Q command don’t tell tap should be recutting the same location each time it back out, just like we cut threads on the lathe, if it wasn’t repeat exactly when it started, you know ...
I looked for but can not find the other G84 videos.
+MJP20121 My apologies! Those follow-up videos will be coming out later this week and next. Stay tuned!
-Mark, from the Haas Tips of the Day
Can i read the value of setting 133 from within a program? that way i could be sure it was on before allowing the program to run.
Yes. We could check Setting 133 with a macro. On the Classic Haas Control (CHC) we can use variable #6nnn to check settings. On the Next Gen Control (NGC) we can access Settings with variables #20nnn.
CHC:
IF [#6133NE1] #3000=1 (TURN ON SET. 133)
NGC:
IF[#20133NE1] #3000=1 (TURN ON SET. 133)
hello sir very intersting
This is not working for us. We set 133 to on & even set 130 to 1 just to see if that was not the problem. Our 6-32 tap, with peck set to 0.313, S320, R is at 0.3" above the material & F10.0, creates tap sized holes. The bottom 1/8" or so of the hole has thread, but the rest of the hole is the tap diameter. Our code format matches what this video shows.
Its too long for 8 or 6 hole i need to know if any cycle like fanuc g84 canned cycle using Q
Nope, it will ignore it
As per your advice on how to use peck tapping , I want to know , how to use G98 code to dodge my clamps, for second hole ?
Thanks in advance I figured out for my question , I used G99 and G98 to dodge my clamps
@@pradeepchoudhary8241 I think the more simple way is to use g98 and set your g43 h value above the highest clamp on the work piece!
Sir how to make a taping cycle in cnc lathe
Should be G74 and the machine should have the capability of low gear running at 100 RPM.
I'm just sitting here wanting that VM3. And some work :(
mrs mark i understand but i want asking someting if my code G84 Z-30 R2.Q5.F200 it will work for peck tap?
+ProLive Advange No, adding a Q value will not work on a Haas control. The procedure Mark describes in the video is the method you should use to peck tap on your Haas. Thanks for watching and for your comments!
+Haas Automation, Inc. thanks for your answer mark :)
with fanuc its just M29 before the G84 line...
Its just M29 code G84 for left hand rigt hand code how ?
NGC only, or pre NGC as well?
This will work on Classic Haas Controls as well.
Sir what is canned cycle and also rigid taping m so 🤷♂️ confuse pls help
Canned cycle are basically G-codes that makes the machine do series of actions instead of one particular movement. They are kinda "shortcut" g-code and make things much simpler to program and easier to understand. Rigid tapping I believe is when the tap is solidly held by something, instead of into a holder that has some "slack" to it. This means the machine has to orient its angle and start at the same exact location when starting the movements, and the movement has to be perfectly synchronised with the rotation of the tap.
@@shadowdsfire ....plus you have to add M29 S300 or whatever speed prior to the G84....this only works on FANUC controllers like Dal-Lih and Mori's.
Ill be using this on 304 stainless 3/4-10 2.0 deep.. No looking forward to it._.
Sir I have one doubt I'm going to one tap its 20 mm length then start taping programm it's going nearly 10 but that time power will go either something happen in M/c . after I'll start everything okay in m/c can I start with same position by using settingrap 133 on
Whats the advantage of peck tapping
Sir please give us CNC turning center videos in your playlist
why not we use Q instead for adding multiple depth.
That's how it works on Fanuc controllers. Fanuc may have an active patent on that system (just like they do with the G54.1 coordinate system) and so Haas had to come up with a workaround.
How about if we are using a canned cycle?
What is peck tapping used for ? I asked my boss and the tool maker and they never heard of it or can find a reason for it and we have special taps for each material we use and I thought it would be handy for the Ti but we got special taps for them recently and as one said you would probably break the tap as its cut would start on work hardened area if you did that on Ti.
Hayden Verstin on deeply tapped holes the spiral chips build up and twist around the tap binding in the hole, reversing the tap and bringing it out of the hole from a depth before the chips wrap up allows them to fall off the tap and not end up back in the hole, so the next depth section is also figured by how the chips form as well. This has saved thousands of broken taps through the years
Hayden Verstin- I forgot to mention I used peck tapping mainly with spiral flute taps, or blowing out the hole with each raise of the tap if it was a spiral point tap
Jadon Cramer quick question, I know this is an old comment, but how do you define a “deep hole” is it a ratio of the diameter of the tap? We’ve had some issues with some 4-40 taps and 2-?? Taps recently and I stumbled upon peck tapping. Just curious what your formula may be, if you’re willing to share
Mark i have a question...where is a typical peck tapping used?and would it over size the threads due to recutting.
can any one tell me where i want to peck tap
In steel holes about an inch or more or even aluminum for example.
Can i apply job to your company
why not just use "Q" ?
+MegaJohnhammond The Haas CNC control doesn't use the Q address to assign peck depth in a tapping cycle. This video essentially shows a workaround for that.
Ditto above....if it's in the program it will ignore it....additionally putting a M29 S300 ridgid tap command will alarm the controller.
HAAS MY FAVORIT VERTICLE MILL JOHN USN
Helo sir...
Please make video on
How to calculate cycle time before operation.....
And How to select suitable toolings....
Thnk you
Just use Q in your cycle 😂its easy
.. we don't do it in cosmos vcm800
So many years have passed and Haas' G84 still doesn't accept the Q value. Consider this before purchasing a CNC machine from Haas. It would be a nightmare if you had 20 - 200 deep holes that needed tapping. Silly machine!
