the entire time i watched this video i thought it was a cnc crash video so i was just waiting for the crash to happen and it never did.. felt like i was gonna have an anxiety attack lol

TO0100 M30 I should get a go pro for work :) Edit cause i forgot to run a finishing cycle on the radius on the front :)

Rather interesting piece as final. We did external turning, external grooving, external threading, center drilling, internal turning, internal grooving, internal threading, milling with C-axis. That covers pretty much most operations needed in normal workshop.

1:58 it enters really hard

Slower RPM. Here's a tip. When you see sparks that means the insert is rounded due to higher speeds for that diameter of shifting.

AGAIN KZfaq? AFTER 4 YEARS U RECOMAND ME THIS? FUUUUUUUUUK

poor lathe :( take deeper cuts and slow the feed rate

I would go slower on the feed and speed and take deeper cuts instead

Feed is too high, cutting edge will wear off faster

Clean finish but you can take bigger cuts on each pass to save time with that carbide insert

Can'd Cycles! Nice looking part.

I think the people who talk about light cuts see too many train machining vids...This was a great combination of depth of cut and feed rate, providing great chip control, which can be harder when you go for deeper cuts and can always jump at you if the insert goes (a safe starting point for machines with limited power is 1-2 times the insert nose radius). The only thing I don't like is the spring passes, which although won't hurt too much on the leaded steel, but can really cause problems at the edge, especially without strictly sharp finishing insert geometries.

Good video, not sure why you faced the ball instead of turning it. With that much material hanging out of the Chuck. Turn the round parts off where you can. Sideload leads to a lot of dimensional problems, when you need to hold tolerances.

give some coolant on cutting bit .pay mercy on bit

Why using chamfer out in threading cycle when U have groove? 2 high Vc, 2 low Ap, second finish pass only made finish worse. Still not bad

Some moves were unnecessary, and that second finishing cut would have worked better on the surface if taken a bit deeper. At the end of the day it seemed to compensate cones and could improve measurement. If that threading tool exited the material before slanting up then its also fine. At 2:00 however it is clear why your school restricts depth of cut - any deeper and that G0 enter would cause issues. If that piece passed measuring and I had like 10 or less of those to do I would not waste time hand programming it in a different way.

A for effort D for execution

Nicely done. Having the second finish pass that essentially takes nothing is sometimes the result of how the controller reads the G71 X values. If you adjust the starting X point or the U value in the canned cycle you can eliminate the extra pass. It really makes no difference with one part but if you were making a large qty. run it saves a lot of time.

my suggestion for you is to turn the part from the front to back and do not face/back turn the radius on the front of the part. the radius could be turned easier and quicker by doing it all in one direction as an od turn. ref. X (dia + .02) z.1 G71 repetitive cycle G0 x; G1Z0; G3 X Z R; G2 X Z R; G1 X; G3 X Z R; G1 Z; X; Z; X Z;

Nice

He has learned the lesson.

Im the gcode programer...... Nice job....

I am a lathe guy myself but all of the shops I've worked in have all had Okuma lathes and mills

Menos avance de corte. El avance longitudinal, desgasta más la punta de tungsteno, que la velocidad circunferencial. Yo diría que utilices más profundidad de corte, misma velocidad del husillo, y menos avance longitudinal.

We made a similiar piece out of aluminium, only it was half of the size of this.

so , did you wrote the raw g code in notepad ?

Warum benutzt Du beim Schruppen nicht die ganze Wendeplatte? zumindest die ersten 4 oder 5 mm ? Dann noch V-konstant dazu ... und das Teil ist in weniger als 2 Minuten fertig! Why do not you use the entire insert when roughing? at least the first 4 or 5 mm? Then V-constant ... and the part is done in less than 2 minutes!

new insert slower rpm higher feed rate! haas st30?

Brilliant job. I'm not keen on 3 jaws with a high feed rate but these tiny cuts are quite safe 👏🏻👍

g50 s3500 g96 s450 m03 that happens because g96 is too high where is the coolant and lube?

Capo mi profe fantone

Butun takimlarin talasi az devri ilerleme hizi hizli oldugu icin elmmas ucu yanio

Amazing

讚，看他的鉄削知道她的刀具讚分享

Do you happen to have the code & pic somewhere? If it's not inappropriate or even illegal to upload, I'd much apprecaite it. I need examples. If you can't deliver, I understand :)

Good job but cooling fluids missing!

2.03 g00 into workpiece xD

What will it be used for? What type of part is this?

If you are taking 2 finishing cuts leave the last cut with something to do.

decrease the feed speed man and keep away from resonance frequency !

Amazing bro

curious to see the whole program and what software was used.

G96 is my favourite

G76 P020060 why you angle on exit of thread?

You can share the program plz

Amazing trik

Amazing the number of CNC "experts" commenting here who do not understand the video title and its relationship to the project, or that this video is 3 years old. Jeez...

Bigger cuts less m/m , 3 out of 10

What was happening with the threading cycle at the end of the thread it seemed to jump before it reached the under cut.then dipped down into the under cut.

im not see any coolant on there.

Hai bro video quality or sound super and Machine Programming man super and this components using work bro ?

Those are some pretty shallow cuts a a really high speed.. Read up on your insert geometry.

NICE Work

What machine were you using?

Étonnant de prendre la passe par en haut !

Super program 👏

I'm not sure what to say about this, i'm thinking that this is they way you were thought to cut a part on a lathe.... Very wrong.... But in the other hand if you programed this by hand I would hire you... I'd spend some time teaching you how to efficiently cut a part bit you clearly know what your doing.

Cutting speed and feed are extremely high.Seems only for demo piece. For production batches, such cutting parameters will never maintain required tolerances

Tengo un cnc y me marca falla en los servidores y k puede ser?

M08!! M08!!!!!

👍👍👍

Nice!!!

Coolant is not hiting the tool properly.. Even though the feed is high we can control the tool wear by providing more coolant to tool edge.. Poor turning program, chance for vibration too high..

車牙刀具讚

why u use a vbmt 04 for 2 operations u can use a vbmt 08 and then you can finish with your tools and why u repass the finition tool that make the finish worst ans how about your groove finish you almost forget it and you have to chek your vc i found it too high

so.. wazzit do?

I so miss to do the gcode.......

неоптимизированная обработка коллега. Попробуйте точить все продольной подачей

This one isn’t half bad. Must be a different programmer. The other video was rookie shit.

CNC hay quá 👍🏆👏👏👏👏🤗😍🤪

現在工作都只放1.5切深 和F0.24 速度加快增加太多的不穩定性

How much rpm ?

wasn bullshit xD

well done! nice feedrate. they dont understand why there is no coolant? :-D ein paar amateure finden dieses video wohl schlecht weil kein kühlmittel durch die gegend spritzt, wer genau aufpasst wird allerdings bemerken dass er es abgeschaltet hat damit überhaupt etwas zu sehen ist. die vorschubraten sind optimal, die zustellung ist optimal, beim gewinde würde ich vielleicht anfangs etwas mehr zustellen. ansonsten perfekt und schön azusehen. fanuc steuerung?

Como eu vim parar aqui mano?

💥💥💥💖💖💖💖💖💖💖💖

Plz program photo

Can u tell me the rpm and feed and depth of cut for using

Colande on

1:10 Turtles having sex

Hlo sir can u send this program

G819 right :)

Is this Swiss lathe?

Plz tell the codes

Your OD roughing depth of cut makes me sad, lol. And your thread chamfer amount makes it do a funny little move at the back of thread. Unless you didn't actually want the thread to run out into that groove/undercut?

M08

Sadece gülüyorum 😁😎

Да... 1к62 отдыхает...

so slow would have gone out of business years ago

Kaba talaş ama onunda bi gururu var aq o ne öyle

2 finishing processes at same z,y ?

glentzer

Que?

Mehr Zustellung bitte, spart Zeit und Geld

Absolute or incremental?

Fuaaa

program send please
