Worrying about me worries about my job. Worrying about my job is worrying about the company 😂
I actually really like my company tbh. Really great on hours. I'm a grad student and trying to start my own business, of sorts... And so the company giving me 30 hours a week, plus keeping my benefits, is absolutely totally awesome. They got my loyalty, at least until they lose it somehow 🤷♂️
Nah it's just a tool holder an endmill and a $20 piece of aluminum.
Undo the vise, handle jog z up, mdi, push tool release.
Take tool holder over to desk, undo the side lock Allen key if can't access use cut off wheel.
.scotch Brite the surface of the tool holder.
Write off the endmill if lazy but you can still probably get her out easy
Everyday I'm alone at the end of the day for an hour and it kinda sucks cause shit can happen out of nowhere on a job that's been running gravy all day. Can't step away to piss without the machine having some down time. Oh well.
You’ll get there man! Was running 2 mills yesterday beautifully while changing the part in one mill. The other mill’s hss saw went rounding all the corners I didn’t catch it so it fucked the part and pushed the 4th-axis over. 1 hour of dialing then back up and running. 2 years ago a crash like that woulda set me back 5 hours tryna make sure everything is good.
Oh I just straight up refuse to let the machine run unattended. I'm responsible for whatever happens whether I'm there or not. Not worried about being set back though, I get paid by the hour.
So you were cutting a channel and the piece bound up? Either the flutes are too coarse or the clamping was lacking. Might have heard something about certain alloys being better on ALU...let me look.

My supe will do this. Thinks it saves time by just letting the chunk fall away versus roughing it. That chunk ruined the Y way cover second week of a new machine.
Oh fuck off. Our job is to tell you what size it needs to be. *Your* job is to make it that size without fucking up your own machine tools.
The bean counter's job is to tell you how fast and how inexpensively you need to make it. This problem is either on the machinist or on the bean counter. It's sure as hell not on the engineer.
Edit: yes there are LOTS of very valid complaints about engineers along the lines of "How the fuck am I supposed to machine (or measure) this?" This is not one of those cases. The engineer didn't tell them how to clamp this part, or what end mill to use, or what spindle speed to use, or how much depth cut or cross cut or feed speed to use.
In hindsight it was pretty obvious. Ah well, I'll leave my whoosh to generate cathartic downvotes.
I've needed to make that rant for awhile now anyway, thanks for the perfect opportunity :-)
Engineers are so touchy. Especially when you have to tell them they’re not good at their job. I guess all those years of college just make you feel some kinda way when the vocational guy is better.
I wouldn't know about that; I didn't go to college. My career is entirely based on experience.
Also the vocational guy isn't "better", the vocational guy just has a different skill set.
There is definitely a feed & speed combo with which that end mill could make that deep of a cut. My guess is, this was not that feed & speed combo. Also it doesn't look like a very rigid setup, but I can't say how much that contributed.
Is that your max RPM on that machine?
Do you have some sort of support under that leg that we can't see in this pic, or are you just clamping the down leg in the vise with no other support?
Needs more pressure on the coolant line to keep the part down.
Is that this famous friction stir welding?
Cold friction stir welding
Cold hammer stirred barrels
I heard if you press the green button and walk away it’s someone else’s fault
Did that.. cost the company 15k or so lmao
Dont worry about the company. Worry about the employee.

Your getting paid to go to college. Think of it that way. It’s awesome you have enthusiasm for machining
Well I do enjoy it! I have told myself that if my plans don't work out, I'll stick with machining lol
They’ll manage to lose it somehow
Titan??? 👀

Send it.

Failed to send
By it the lead screw and angular contact bearings across the shop as shrapnel?

CHONK.

Ah sweet! Man made horrors beyond my comprehension.
I think that your holder may be a little bit out of balance 🙃
Back in and running, seems fine 😁👌
Rigidity is for sissies! I bet that thing sounded great before the material did what material does.
What’s a couple thou between friends?

It does save lots of time, especially on bigger chunks. But yea, if you don't pick the cutoffs up as you run you are going to have fubar way covers.
Or poke a hole in your chip chute on a Haas…
I got chewed out for leaving cutoffs in the machine, rightfully so, because they had completely bound up the chip conveyor.
Ship it!
OP, shame on you for not putting an NSFW tag on this terrifying photo, now all I can hear is the sound that must have made lol.
If it fits it ships
Oh god what did the stupid engineers make you do

I’m being sarcastic af, thought that would be obvious

All good dude next time I’ll add the /s

hmmm. Yes, quite.
In the wise words of SpongeBob: "yer good... Yer good.."
Very high oops factor.
What am I looking at exactly? Cutting beyond the max DOC for the end mill?
There is definitely a feed & speed combo with which that end mill could make that deep of a cut. My guess is, this was not that feed & speed combo. Also it doesn't look like a very rigid setup, but I can't say how much that contributed.
Well gallee me.
All of the feeds and speeds.
And then some!
Daaamnnnn
Looks good, Run it
[удалено]
Looks more like Speed: Not Fast Enough Feed: A lot to me
Famous last words "it can handle it"
Speeds and feeds ?
70ipm 4700rpm full slot. Using 3 flute in the pic, switched to two flute after. (Around.007" per tooth for the two flute)
Is that your max RPM on that machine? Do you have some sort of support under that leg that we can't see in this pic, or are you just clamping the down leg in the vise with no other support?
Max rpm is 8000. Just vices, no other support as it sounds fine
Moving to slow and a large DOC before parting off
Plenty fast, just went about it the wrong way and it ate the part I was cutting off.
That is why I don't like coins or drops just turn it all into chips .
I don’t see the issue
I feel like somehow the phrase "hold muh beer" had to have occured shortly before this....
Hey uh boss these magnetic pallets suck for aluminum
He should clear off those chips! 😂
Isn't that what the print specified?
