Lol, very nice work. I think you should leave the bit in there so it looks like you did it on purpose :D . Brings back memories of all the times I've smashed bits into the material I was working on. But other than the bit sticking out it looks awesome, I'd love to have one of those awards on my wall. Maybe you guys should make a whole load of those and build some Lego forts :D .

Is that machine wax, plastic, or something else?

Looks like someone forgot to change an offset or one a million other things... :ahh:

Re: pic: Lego Award
 

I'm guessing that it's plastic. And if you we're putting in the g-code statement by statement, I wouldn't be surprised if someone misplaced a decimal point and went down 6.3 instead of .36 :yikes:

Re: pic: Lego Award
 

It's metal. Acutually from what I heard from the operator, who shall remain unnamed, the machine read a M1 code wrong. I think its M1 correct me if I'm wrong but that says for the machine to stop.

I don't think crashing a CNC machine is something to be proud of.

Re: pic: Lego Award
 

definatley not when i was around

Re: pic: Lego Award
 

its not that we were proud of it, its just that making mistakes can be something to look back and laugh about sometimes. like this one. :D when i saw this i was in shock. :yikes:

Re: pic: Lego Award
 

We arent proud of this but this kind of thing happens all the time in our shop. Its the kind of thing that happens when you are in a machinee shop. The only way you learn is to make mistakes and the operator learned something. So I see this as a success because the ultimate goal is to educate. We had many extras and we got a 1/16 ball endmill and finished the engraving with it whiched turned out to have a better finish to it than the engraving bit.

Man, I don't even know what to say to that. I'm not saying I've never crashed a machine. But I know the one time I did, I never wanted to again. I was very embarrassed that I made such a careless mistake, and I was very concerned about the "health" of the machine. I usually try to learn by watching someone who knows what they are doing; not buy toying around with something I should have no business messing with. When you work at JPL, and you drive the Mars rover off the table by mistake because you weren't sure which button to press. They aren't going to say "oh well, at least he learned something" when you just cost them a few million dollars and multiple months of hard work. When you open up a computer monitor to repair it, and you accidentally grab a hold of the CRT, you might not even get to learn anything from that experience because you might be dead.

While making mistakes is a method of learning, it is certainly not the only method and I don't think it is a great method of learning.

If I had the luxury of owning a HAAS CNC, I'd take care of it like it was my child.

Re: pic: Lego Award
 

its not that we dont take care of it, believe my that machine is my third arm if i can say anything about it but when people learn mistakes are inevitable
our team member was doing awards when he had been machining for about three weeks by himself which is quite an accomplishment and out of 60 parts he only messed up one because of some bad coding
and the mistake wasnt that amazing honestly he just stuck the engraver into the part, no damage to anything else because he stopped it in time
also had i been there i woulda tried to make sure but since our team only has two people who know how to run the machine and hes one of them and i couldnt be there it happened
hes a good machinist tho u should see our vex awards =]

Re: pic: Lego Award
 

also that is my hand holding this and i took the picture =o

Re: pic: Lego Award
 

The first time i crashed a CNC was in the 6th grade. Our team was showing me how to work a CNC at basic commands. The veteran mentor was right next to me and i scrolled the z axis down to much with out switching the nob to a smaller amount. I smashed right into the part. At that time i was really really scared i couldnt believe i did that and the members of the team were going crazy trying to look for another bit. It ended up ok when they found the tool. I proudly put the part on my desk and the part is still there right now. We treat our machines better than royalty but it doesnt mean we never screw up once in a while. And when we do after we make sure everything is ok we can just joke about it.

Re: pic: Lego Award
 

only time i crashed a cnc due to operator error was when i broke a 3/4 inch 60 degree helix carbide endmill (not the cheapest of tools) because i slide held the machine and turned off the spindle bnefore it entered a part and forgot to turn the spindle back on and ran the part =/
after that i only broke like two or three small endmills when i tried making our parts go faster or just the wear and tear of an engraver bit until it needed to be sharpened and ive been machining a long tiem

Re: pic: Lego Award
 

Okay guys, lets not turn this into a thread about when they first crashed a CNC. Since you guys know my authority, you better listen. Making mistakes is the most frequent happening in FIRST Robotics. It is a great way to learn, at this stage. These mistakes teach us how to not drive a Mars rover off the table and not to touch a CRT. Mistakes are a big thing in FIRST. Its what makes and "breaks" matches. Okay, enough being big brotherly, which i literally am.

Re: pic: Lego Award
 

Well, I can care less about crashing CNC machines.. I'm sure most machinist have done that one time or another.
I know I personally made some bad G-code errors in my CAM class.

But anyways, on to the important question.

What are you going to do with the (ruined?) hunk o' metal in the shape of a LEGO block? Please tell me it's not gonna get thrown out. :ahh:

If that's the case, as a LEGO enthusiast, I would offer to take it off your hands instead of seeing it go in a dumpster. :)

Re: pic: Lego Award
 

uh it was one of 50 awards, only bad part so its going on the trophy wall of mess ups =.

Re: pic: Lego Award
 

[offtopic]before i read the blurb on the picture i thought you had converted it to a radio... maybe you could do something like that?

Re: pic: Lego Award
 

Maybe we could but we have to get ready for build season now. That would be pretty cool to do. We could put it in our pit(if we can get a signal from inside an arena) and play music from it. A coustom lego radio :] !
