Stupid Human Tricks!

[nofalloff]

I think I forgot an M08 somewhere! This wasn't the most encouraging thing to have happen when I tried to make my first part with out a professor or the lab tech helping today. Think I need to check the spindle speed also.

D’OH!

[chris m]

Wow! Was that endmill recovered from the wreckage of the Titanic?

 

Just wondering....

Is it over 22,000 rpms if not the speed is fine just need to flood it and change it to a 2 flute to get chip evaucation and should be fine.

 

Good luck and yeah been there done that enough times believe that.

[Teh Bear without Brains kinda idiot]

And check spindel direction too ,M03 nnot M04 !!

Cut should be going x&y at 20 ipms not in z. Cutter looks to have a couple grinds under its belt.

 

nofalloff, this is what is known as school of hard knocks and its #1 for training, learn from it and move on to next project.

[Storkman]

don't feel too bad, I've seen much worse.

The very first thing I learned about machinery was that it is not a matter of if...But when?

 

+1 on the:

 

"learn from it and move on to next project."

[Code_Breaker]

That looks like 6061 Al. Is it?

 

If you want to cut aluminum, use a 3-flutes. The chips has a better chance to clear. Also, better than a 2-fluter.

 

Just a thought . . .

I have an endmill in my toolbox that looks just like that . I keep is as a humble reminder. It's just as important to know what NOT to do .

looks like you need a regrind

 

i've never ruined an endmill...ok, I lie.

 

hope it wasn't the final exam

 

its a learning experience like the guys said. it happens to the best of them. glad you showed us, it was good for a laugh. on the serious side, though, it's always best to measure twice, cut once. Nothing beats experience when learning.

 

OK, got a mold ready to machine now...gotta run. I think I'll recheck to make sure coolant is on

[foolsh]

to make sure coolant is on all the time,delete the M09 from all your programs

[TheePres]

YEE-HAW!!!!

Push it till it melts.

[MetalMarvels]

You didn't hold it in the cut quite long enough to get the true "lollypop" shape......

 

Been there done that on an overnite run when the coolant pump died.......Hot Tool!!!!!

[mold100]

Yea well have you ever melted (i mean WELDED one of those p.o.s. iscar 1 fluters (1/2) to a piece of steel to the point when you loosen the vise to move the head up (because of Z axis overload) and take the tool out of the spindle to break it off the part? did that one quite a few years back, and they still claim its a good plunging tool.

[I. Anderson]

Don't feel bad. My nickname in school was "Crash"

 

The best one I did was writing a program by hand and forgetting to turn the spindle on. I pushed a 3/8 drill right through a 1" block of aluminum.

 

It was after that incident I figured out that a good slide hold technique beat the prayer method every time.
