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.
Agree. As deep a cut as the part can handle first, then increase the feed as much as possible. The speed is what wears out inserts. Deeper cuts increases wear very little, increased feed increases wear a little more.
@@tomislavmijatovic9369 deep cut slow feed technique brings too much heat to parts. I would take first 0,4mm per rev feed (with 0,8 TNR, more with bigger TNR) and then see how deep it could go
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.
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.
A G71 type 2 will always take an empty cut from what I've seen. It might be meant to cut the edges out that type 1 leaves but type 2 finishes those after each cut so the cleanup pass cuts air. Could save a little time by using type 1 when possible so it doesn't clean them up twice
@@SURASSUH I have since learned that the "empty" pass is an intermediate finish pass, you can program it so that it actually cuts material on that pass as well.
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.
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.
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 :)
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!

Und Vc runter und stadessen mehr ap. Dann kann man sicher Kaffe holen ohne Angst zu haben, dass die schruppplatte abraucht..
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.

That's some mesmerizing shit right there! Especially at 2:33.
Okuma are work horses. They repeat and keep repeating. I have nothing bad to say about okuma. Except they have a weird language. I cut my chops on okuma. One of the best in the business.
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.
it depends on the machine and set up... I ran pony rods for frac pumps , mori sl45 3 jaw . clamped on 11" dia 3/4 depth on jaws parts 18" or so long.. used tailstock/center.. ran about .315 depth of cut to the side at .021 feed per rev. the flange area was 7/8 wide was the reason for clamping on 3/4" ...11" down to about 3.5" on dia. cycle time was under 15 minutes... guy running them before me only took .08 to the side and the cycle time was like 50 minutes...
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.
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
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
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?

Es wurde absolut keine Rückzugsebene oder ein Sicherheitsabstand beim 55grad stahl verwendet und die Zustellung ist viel zu gering.Wer sowas in einer Firma auf lange Sicht anwendet arbeitet nicht lange dort. Die Zustellung beum Gewindedrehen ist genau richtig weil er entlang einer Gewindeflanke zustellt. Scheint als müsstest du mal nen gescheiten Lehrmeister kriegen
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..
ZLY WEISIOR Yes I work a mazak nexus 450 and z is horizontal with the spindle then you have x and y but you don't need the y axis for this job. Not on my machine.

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?

I should get a go pro for work :)
Edit cause i forgot to run a finishing cycle on the radius on the front :)
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.
most definitely too high of rpm.. the sparks flying show your burning up the insert..
1:58 it enters really hard
I just feel like they can't make up their mind 2:26
I would go slower on the feed and speed and take deeper cuts instead
Agree. As deep a cut as the part can handle first, then increase the feed as much as possible. The speed is what wears out inserts. Deeper cuts increases wear very little, increased feed increases wear a little more.

Clean finish but you can take bigger cuts on each pass to save time with that carbide insert
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
poor lathe :( take deeper cuts and slow the feed rate

What will it be used for? What type of part is this?
so , did you wrote the raw g code in notepad ?
new insert slower rpm higher feed rate! haas st30?
G76 P020060 why you angle on exit of thread?
g50 s3500

that happens because g96 is too high

curious to see the whole program and what software was used.
It was probably hand written utilizing G71, G72, G70, you don't need CAM programs for lathes that have the canned cycles available

wrong height in the thread program or the output angle in the machine settings should be changed
give some coolant on cutting bit .pay mercy on bit

Too much and not enough.
decrease the feed speed man and keep away from resonance frequency !
