i hate you


ive been machining my $@#$@#$@# off for 2 weeks and im not nearly that far

[Cody Carey]

Wow, that is nice. We just got our parts back from one of our sponsors, too. They were laser cut, but some of the cuts failed to go all the way through the .20 aluminum plate. We had to finish the cutting with a jig-saw.


I wish they had a water-jet :D

[redbarron]

Awesome!! How are you assembling all that? Welding? and how long did that take? Nice job

[Tytus Gerrish]

the cutting time was 2 hours and 49 minutes

[ChuckDickerson]

How much does that pile weigh just out of curiosity?

[Tytus Gerrish]

29 pounds

[ChuckDickerson]

Sweet!

[redbarron]

Are you welding that together?

Ohh Tytus, I love you

[Guy Davidson]

Nice, very very nice. We have access to a lsaer jet we use to cut acryllic and lexan for prototypes and parts when needed, but we mill, lathe, cut and burn the rest of the parts.

I wish we had a waterjet. We sent our stuff to be machined last weekend and its gonna take about 1.5 weeks to get every part back.

I wish we had a Waterjet just to make our robot look better, but our teams manufactures every single part that we use which can take a shorter or longer time to do things but it's nice.

[Kyle Love]

I spy a frame rail.

[mizscience]

Very nice. One can never go wrong with a waterjet cutter.

well, actually, one can, but that's another story, lol

:]

[DonRotolo]

Yes, I am jealous. very nice.

[windup zeppelin]

hope you end up with a clean beauty of a robot.

[Cody Carey]

All those parts are sitting atop a schematic of the base... I didn't even notice that before.

[JamesByrne]

I do want a water jet also, those parts look pro. they are clean, i am jealous.:)

[MarsBOtkid]

Looks VERY familiar.............:rolleyes:

Laser would only take about 30 minutes to cut all that, and it would not have any draft. But, you would have to deburr.


Nice job looks like you have a lot of welding to do. maybe think about using 3/16 pop rivets in your design next time with an air rivet gun.
Bend flanges on the parts to rivet into.

The welding will weaken the aluminum by taking the hardeness down to T Zero at welds unless you have the frame reaged.

Don't eat to much of the paste. Even though it tastes good.

My understanding is that some fancy water cutting machines angle the nozzle to compensate for the draft angle. At the very least, that may not be a concern.

We've had a lot of 'fun' trying to tweak our plasma cutter to produce as little dross and draft as possible. We're getting better at it, but it's still frustrating.

the waterjet used on these parts is a 5-axis machine. we programed it one time to blast around 6000 small holes Arround this hemispherical part. but 99% of the time were only using 2 axis like this time. the draft is minimal with aluminum so it can be cleaned up in the important places with a file
