School limited my feeds and speeds, though partially because I'm not using coolant so I can film this. The initial groove is there because grooving without coolant is a big no-no.
The work on this is beyond words. As a novice Cnc op. How he touches off the chuck to pass over air before the rough cutting begins ending at a light caress finish that leads to an almost water marked mark to end the program with a thread psÿcl amazes me all without coolant and almost tattoo like style, my hat is off to you good sir.🙏🏽
When we did this in our school the professor was right there over our head to watch us. But it is a try, from a student, who can be better tomorrow if he tries. No need to judje him. Because when all you started this job you didnt knew a shit !
I knew it all just ask me. I was God's gift to apprenticeship and I thought so. Shaking my head. I think Bob Seeger said it best "wish I didn't know then what I don't know now." Arrogant little prick.
We have some haas CNC in school too, but I did not know mechanical engineering student can use it until few weeks ago, since these fancy stuffs are in aerospace school building. I only used manual lathe in this semester, this part could take me a month using the manual lathe. Definitely make works much easier!!!!
Quick code on a haas lathe makes them one of the easiest machines to operate. I used to run one of these and it was by far the best thing since sliced bread
You're learning. I've taken a class as well and had a teacher not qualified. Im lucky to have a machinist that's willing to help my mistakes. Hope you find one too.
yes it's a cult ritualistic ceremony called ghosting.. you do it when you want to give a big fuck you to your company or boss and are thereby accepted into the human shit pile of lazy inefficient garbage
We learn through mistakes and gain experience at the same time. You didn't crash that matters more than the part. Finish of the part can be better but just keep trying there bud!
Just wanted to say that after reading all these comments I wonder how you ever dared to put an other video online? Don't get discouraged, your still in school so don't mind what other people tell you to do, at least you are learning a trade that can get you somewhere, I'm in Europe so It's a bit far I think but I'd hire you I'm sure after a few weeks in our company you'd do things like this with your eyes closed! I myself never had the chance to learn CNC programing, when I went to school it was all conventional milling and turning however when I got out of school I continued the conventional way for a while and bought my first Haas CNC (Super Mini Mill 2) when I was 25 after working in some small company's I decided I could do this work myself! so a year later I bought an ST10 and went on form there, in a few weeks I'll be getting mu new VM-3 so I didn't know s*** about CNC programming and now I work full time for the automotive industries as well as many other sectors! I'm 32 now and in just 5 years I have gone from not knowing simple G code to operating small and large CNC mills, lathes, Wire EDM, Sinker EDM, CNC grinding etc... So no mater what you learn in school it's what you do afterwards that counts and how much effort you will invest! Don't give any attention to what other people say to bring you down, chances are at one point or another they will always bump into someone that is way smarter than they are, but then again I don't think those people would acknowledge it!
+Kurt Bleyweert crazy right! I get 2 or 3 messages daily with people calling me stupid! It doesn't bother me tho, I was in school, now I'm workin. Not only do I enjoy it, and have gotten better, but it's also caused me to believe a lot of my replies aren't actually machinists!
Most insert packets have recommended speeds and feeds on them. Your SFM looks good in most of the videos, but your feedrate for roughing is way too high and your DoC is too low on almost everything, but especially on finishing. The result is poor tool life.
Cool video, keep it up, You just need to learn the Canned cycles, specially G71. The only criticism I have is that around the 5 minute mark you took a skim cut and that's a no no since it wears out the tool a lot faster and you also kissed the chuck a bit but then again you're in the process of learning so GOOD JOB ^_^ As for Doug, you see he was born knowing everything, He never went to school or had to pick up a book or learn a thing.
A lot of times it not uncommon to brush the jaws of the chuck do to inertia from the jaws clamping force. If the jaws are properly turned this is not an issue. But with raw stock being what it is, occasionally jaw flex can occur. Now close/clamp jaws shut & Run an indicator across each face and chances are they’ll all be out a very small amount. Now spin that chuck at 3000 rpm, and rotational mass takes that to a whole new level. Not to mention this is a student learning here and we all have crash a tool, myself included. Ive been a CNC machinist 39 yrs. that’s called learning.
STGvHaaren1 the sudden harsh starts and stops, rapids to nowhere are hard on the machine. Thats the difference between an owner and an operator i guess.
vitsou1 That was my first thought as well. You can see it immediately in the finish. I'm still pretty new at this myself though, so I may be talking nonsense. lol.
"Practice" makes you better. Try different Vc and ap vs feeds. When your tool makes sparks then it will brake soon. Try Vc 180, ap 2 - 2. and feed 0.2 - 0.25 for roughing. Though it's brass, these settings work fine with me in mild steel
I'm pretty new at this as well, so take my comments with a grain of salt. And if any old timers on here want to correct me, please do. It does look like the feed is too high for the speed. If the school set your max, you probably still would have wanted to reduce your feed to compensate for the lower speed. It also looked like it was wobbling kind of a lot at the beginning. Yeah, turning will take care of most of that, but if there's a tight tolerance on run out, I don't think you'll get less than .001 on that. If they don't care then I guess that's fine. No point in indicating if that's not an important feature. But since it's a school project I would assume they wanted something like that. So I guess my question is, did you indicate the stock when you put it in, or am I just seeing things?
Have they shown you how to use a dti yet? XD would have made the groove concentricity a lot better. good start though looks like you're learning a lot :)
Ok.. as a lathe programmer this hurts my head, why on the end contour (radii) didn't you use a G71? Why all the air cuts? Why were there two finish passes (second of which did NOTHING!) I'm going to program and run this this week in spare time... watch for it
It looks like your work offset was set in front of your part .100 or so, I guess its a good thing or it would be another lathe crash video. I'm glad to see kids trying to do something other than invent some stupid APP.
needs a center drilled hole with a tail stock the thing is moving all over the place. That would also allow for greater depth of cuts and better finish...that machine cuts air really well though....lol
Ideally I would agree that the part needs a centre but for aesthetics! No there shouldn't be. And with the cutting of the air.... The program was set to stock diameter which would produce a fully finished shoulder taking in to consideration that the part was previously ran of course he's going to be cutting air with the small depths of cuts he's making. Does anybody in the comments section here have any ability of foresight to see why the part was produced like this?? Lol
Good Video. Dont get discouraged by idiots. We all started off not knowing anything. Hey you didn't crash the machine so you're doing ok lol. google a feeds and speeds calculator and go based off the manufacturers specs.
Me doy cuenta que al principio cuando desvasta el que programo hizo codigos inecesarios ya que no tocaba el cortador con la pieza Pero eso no es tan importante aun asi hizo un bien trabajo
Hey guy, im a german machining mechanic ( Zerspanungsmechaniker ). First it is not a bad Programm for a prototyp part or for a teaching example but in a series production u will never become much success with that many air cuts and the horrible finishing process.
Hey guy!!!!! It is a bad program!!! A simple turning G71? G72? Or is it G70? Canned cycle will work way better than this morons program!! I would fire him right away! Or make sure he's not making more than 16/h cause that's about all you would make in my world!
Can I have your real name please and what school you are going to? I want to make sure I never hire you or any of the students that go through this "training".
+Doug Hanchard Not interested in getting hired by some fat diabetic. Looking for real employment, not someone who's a walking billboard advertising a lack of self-discipline. Thanks
roughing part hurt my heart and my soul everytime that insert entered the part. Feedrate way too high, dept of cut way too low. I wouldn't risk a tool only to be able to film it tbh.
I take that for the purpose of video shooting there is no coolant. If you apply even minimum coolant, there isn't much to see of the actual turning as you can only see that spray from the coolant. It seems that feed rates are pretty good so that most of the heat is put on the chip (yellow chip) apart for few passes on Z-direction (purple chip). Sure, carbide inserts do not have as much of life as with fully cooled turning, but for the sake of the video it seems like pretty good trade-off.
Ideally, it would have a greater DOC with less feed. Overall not too bad, gotta start somewhere. Your radial depth should never be less than you tool nose radius, generally speaking.
Skyler Atkinson Just curious, what was your sfm set at and what was your feed rate? The material you're using is a mild steel if I'm not mistaken, so larger roughing cuts would not have been a problem while cutting dry, by taking multiple light cuts you're not allowing for proper heat dissipation. I'm also wondering why the finishing tool was starting way off the part when machining the front face, I'm guessing wrong offset? What level school are you attending? Not trying to be condescending, just curious. :)
The work on this is beyond words. As a novice Cnc op. How he touches off the chuck to pass over air before the rough cutting begins ending at a light caress finish that leads to an almost water marked mark to end the program with a thread psÿcl amazes me all without coolant and almost tattoo like style, my hat is off to you good sir.🙏🏽
That was beautiful
4:55 did anyone else hear the tool holder hit the jaws?
+Thomas Dodd yeah I did, lol
spooky
I did
나두 들었다
Well it won't do it again so that's that
When we did this in our school the professor was right there over our head to watch us. But it is a try, from a student, who can be better tomorrow if he tries. No need to judje him. Because when all you started this job you didnt knew a shit !
true story!!
I knew it all just ask me. I was God's gift to apprenticeship and I thought so. Shaking my head. I think Bob Seeger said it best "wish I didn't know then what I don't know now." Arrogant little prick.
yeai agreee but the 1st thing we learned in school is not to have empty passes like this :D
We have some haas CNC in school too, but I did not know mechanical engineering student can use it until few weeks ago, since these fancy stuffs are in aerospace school building. I only used manual lathe in this semester, this part could take me a month using the manual lathe. Definitely make works much easier!!!!
Quick code on a haas lathe makes them one of the easiest machines to operate. I used to run one of these and it was by far the best thing since sliced bread
Ohh this is the one that crashed out and is all over the interwebs. Its actually nice to see what became of it
4:65 Regards from the Revolver - it had sexytime with the chuck.
+Bill Klätsch you got minutes with more than 60 seconds? :D
MrDinoooooo
Yes, but never at sexytime. At sexytime minutes are only 55sec long.
thats exactly how long I can last when I have sexytime :)
good thing google has stoopid (R) built in
For someone just learning to program, this is not too bad. keep at it and the fine touch will happen....
at 4:56 it sounds like touched the chuck? :)
You're learning. I've taken a class as well and had a teacher not qualified. Im lucky to have a machinist that's willing to help my mistakes. Hope you find one too.
5 passes cutting air?
yes it's a cult ritualistic ceremony called ghosting.. you do it when you want to give a big fuck you to your company or boss and are thereby accepted into the human shit pile of lazy inefficient garbage
He's stopped his program for changes mid way!!! Does that make sense?
I'll bet those passes weren't cutting air when this part was roughed out before the video started
Oh... you only watched the first few seconds then...
We learn through mistakes and gain experience at the same time. You didn't crash that matters more than the part. Finish of the part can be better but just keep trying there bud!
說的是實際應用程式設計讚
There’s a fail compilation that has this part. That’s why it was cutting air and the part was partially machine and weird at the face
Hey boss, can I have a new insert?
Boss: didn’t I just give you one yesterday? Tf did you do with it?
Just wanted to say that after reading all these comments I wonder how you ever dared to put an other video online?
Don't get discouraged, your still in school so don't mind what other people tell you to do, at least you are learning a trade that can get you somewhere, I'm in Europe so It's a bit far I think but I'd hire you I'm sure after a few weeks in our company you'd do things like this with your eyes closed!

im also a new in machinist and still learn ....thumb up for make this video . don't feel bad for other people criticize you. Keep a good work.
Education is never ending ... Tell me when have you learned everything the world has to offer?
Most insert packets have recommended speeds and feeds on them. Your SFM looks good in most of the videos, but your feedrate for roughing is way too high and your DoC is too low on almost everything, but especially on finishing.
The result is poor tool life.
Also the program is garbage... Takes mich too long!
Sounded like you skimmed the jaws on the finishing pass there
Cool video, keep it up, You just need to learn the Canned cycles, specially G71.

Poor machine, thats a nasty ass program.
+Diesel Ramcharger .... poor machine realy ... i dont see a problem with it, if there whas coolant .....
STGvHaaren1 the sudden harsh starts and stops, rapids to nowhere are hard on the machine. Thats the difference between an owner and an operator i guess.
+Diesel Ramcharger jup
+Diesel Ramcharger its a turret lathe though, they can make movements like that with no issues..
Dean Hartley I disagree. But to each their own.
Too much feed for roughing = tool kill
vitsou1 That was my first thought as well. You can see it immediately in the finish. I'm still pretty new at this myself though, so I may be talking nonsense. lol.
"Practice" makes you better. Try different Vc and ap vs feeds. When your tool makes sparks then it will brake soon. Try Vc 180, ap 2 - 2. and feed 0.2 - 0.25 for roughing. Though it's brass, these settings work fine with me in mild steel
Agree. I personally would lower feed and increase depth of cut slightly (high carbon?).
I think Vc 150 is better for roughing. That's how we do it in our company.
I do vc 260 f=.35 ap=2.5 roughing NP
I'm pretty new at this as well, so take my comments with a grain of salt. And if any old timers on here want to correct me, please do.
It does look like the feed is too high for the speed. If the school set your max, you probably still would have wanted to reduce your feed to compensate for the lower speed.
It also looked like it was wobbling kind of a lot at the beginning. Yeah, turning will take care of most of that, but if there's a tight tolerance on run out, I don't think you'll get less than .001 on that. If they don't care then I guess that's fine. No point in indicating if that's not an important feature. But since it's a school project I would assume they wanted something like that. So I guess my question is, did you indicate the stock when you put it in, or am I just seeing things?
This is airsharpening lathe!
Would Love to see an example of making a Rotax 277 2 Stroke Crank Halves or other Rotax Single!
Have they shown you how to use a dti yet? XD would have made the groove concentricity a lot better. good start though looks like you're learning a lot :)
tool holder: *"I want to die"*
What about the inserts?
Is coolant banned in your shop?
Ok.. as a lathe programmer this hurts my head, why on the end contour (radii) didn't you use a G71? Why all the air cuts? Why were there two finish passes (second of which did NOTHING!) I'm going to program and run this this week in spare time... watch for it
we all learn from a mistake right ...keep it up man
If i dare to do this at my school they are beatin' my ass
+Llama power Got clearance from my instructor for the purpose of making the video
es mi impresion o esa pieza a salido volando? esta descentrada y tiene marcas de varia cogidas....
I feel like the part is wobbling
Face you, in my opinion gave variso pass any increase in the Void, this program MUST be regenerated
It looks like your work offset was set in front of your part .100 or so, I guess its a good thing or it would be another lathe crash video. I'm glad to see kids trying to do something other than invent some stupid APP.

wow your cutting air like no body's business wow adjust your depths of cut not to mention the feed wowow
jorge vargas lmao calm down
Adjust the start point...diameter!
Good Video. Dont get discouraged by idiots. We all started off not knowing anything. Hey you didn't crash the machine so you're doing ok lol. google a feeds and speeds calculator and go based off the manufacturers specs.
Hello, do you still work at the Haas lathe?
I think i've seen this in a CNC Crash Compilation
Daaaamn, pretty bad programming. On 4:45 you hit the chuck.
Me doy cuenta que al principio cuando desvasta el que programo hizo codigos inecesarios ya que no tocaba el cortador con la pieza
Pero eso no es tan importante aun asi hizo un bien trabajo
Hey guy, im a german machining mechanic ( Zerspanungsmechaniker ). First it is not a bad Programm for a prototyp part or for a teaching example but in a series production u will never become much success with that many air cuts and the horrible finishing process.

damn nigga you got rekt. fatty
Your comment is bullshit, fatboi.
A bunch of master machinist in the comment section
i was waiting CRASH. why part is on chuck like that? its gripping only 1/6 lenght of piece lol.
and yes hand programming is easy G71 G72 G76 G2 G3
m4 at the beginning or is it just the video?
too fast...
very nice
what lathe was this done on ?
From what I can see your feedrate is way to high and your depth of cut is too small, you'll increase your tool life.
That single point thread tho
No coolant? Why?!
why do you need to stop the rack @ 2:20 and forward again and again? I don't understand?
asdf, but then again I'm a very beginner. Never done that shape.
roughing part hurt my heart and my soul everytime that insert entered the part. Feedrate way too high, dept of cut way too low. I wouldn't risk a tool only to be able to film it tbh.
if i would see one of my trainees cuttin air like this i would slap the hell out of him
can you show this program please
Why are you face turning?
what is that cutting tool. forged steel, brass oxide or carbide?
+Matt Smith its a carbide...
wth is brass oxide?
Sir muze program banake dikha do may Haas machine pe Kam Kar Raha hu
Type 2 G71 to center would of made this 6 min video a 2 min video
Big allowance
They limited ypur speeds amd feeds because it already chuncked once clearly lol
Why did you engage the M23 before the threading there is no relief to be cut it's just cutting air, unnecessary
Very much NOT the way I would have programmed that part!
What the hell was that? all wrong.
100% agree. But he's learning, lots of mistakes to build from.
way are you not using coolant on the turning process you will burn the turning bits out,
I take that for the purpose of video shooting there is no coolant. If you apply even minimum coolant, there isn't much to see of the actual turning as you can only see that spray from the coolant.
It seems that feed rates are pretty good so that most of the heat is put on the chip (yellow chip) apart for few passes on Z-direction (purple chip). Sure, carbide inserts do not have as much of life as with fully cooled turning, but for the sake of the video it seems like pretty good trade-off.
I think using coolant is more better for your workpiece and bite
And when the bite is blighting = bite going to die
so I mean use coolant or take the low feed
Ideally, it would have a greater DOC with less feed. Overall not too bad, gotta start somewhere. Your radial depth should never be less than you tool nose radius, generally speaking.
How many of these have you made? Hahahahaha
Why no lubricant?
Becaus he was recording.
at 4.55........oops.
朋友說讚分享
大哥給我大開眼界刀具足夠讚分享
This is my job at the school in indonesian
The reason you crashed that part the first time was because your feedrate was too fast... Decrease your feedrate and inrease the DOC
4:54 chuck hit? :P
BomenJager 😂😂😂😂
if i programmed like that i would have got the sack
Just about everything is wrong with this
Profi !
A R 4:03😂😂😂😂😂
What the hell was that at 4:03???
daniel mclean 😂😂😂😂😂
Ap 0,5mm professional ;p
can tell you hada ew goes settingbthe bar in jaws with al those jaw marks on it
Depth of cut is too small and the feed is too fast.
What's the machine and material?
It's a haas st-10 cutting 12L14
Was the DOC edited for lack of coolant? Just seems awful shallow for roughing passes.
Yah, only cutting at .025 due to cutting dry, and school rules.
Skyler Atkinson Just curious, what was your sfm set at and what was your feed rate? The material you're using is a mild steel if I'm not mistaken, so larger roughing cuts would not have been a problem while cutting dry, by taking multiple light cuts you're not allowing for proper heat dissipation. I'm also wondering why the finishing tool was starting way off the part when machining the front face, I'm guessing wrong offset? What level school are you attending? Not trying to be condescending, just curious. :)
1972frenchi indeed cut depth would help !
One of the worst programming that i have seen.
This was when he was in school learning, gonna make mistakes of your gonna learn
This guy is a BUTCHER!!
What a waste of machine time... And mine.
you should rather take bigger depths of cut and a slower feedrate
This workpiece was got accident😀😊
Canned codes dude, just canned codes
What tha hell too many free cuts
I don't know how tool did not broke...
I don't know how you learnt to spel!!?
This is how not to program a part ! Burrs , bad finishes , worn inserts , too fast of feeds and speeds !
this program is sooo weird
Wrong speed
Way to high rpm bro !!!! And the constant surface speed is wrong !!! Retracts way to far - but it looks like a good program .
"Looks like a good program"? Fired get the fuk of here with your lack of experience!!!
ДИЛЕТАНТ
Feed is exta fast....
Blue chips at 5:07. Not good.
Incredibly drawn out procedure for a simple cnc part....
No coolant is ridiculous... can see that by the finish and the fact the insert is sparking... could do a better job manually surely.
+Daniel Walden If I'd have had put coolant on it, there'd be no video. How don't you understand that?
why wouldn't there be a video ?
+Daniel Walden Because the coolant will splash everywhere and you can't see anything? Insert brain pls
called a waterproof camera LOL
Called "coolant-on-lense=no-vision" LOL ROFL xD LOLOLOL idiot
