Show off your machining!

[sanddrag]

I've always had a liking for some of the nice machine work that goes into FRC robots. I'm one of those people who comes into your pit area and really takes a close look at your robot, because I have an eye for the details. It's disappointing to see that many students don't have an eye for the details, especially when it comes to machined parts. We all know a handful of teams that do really nice work in this area, but I don't think we've ever had a Chief Delphi thread for teams to show off their nice machining work.

So, show off your machining! It can be mill or lathe, manual or CNC. For now, let's leave waterjet, plasma, saw cutting, and sheet metal forming out of it.

If you have a description to go along with the picture, that would be awesome. I'll come back later with a few of my own if I can dig up some pics.

Heres a picture of my teams new swerve drives.
They have a one peace frame milled from 3" by 6" extrusion.
I would consider it to be quality machining.

They look really nice. Do you make new ones after kick off?

Interesting gearing choice- The sprockets are about as large as the wheels.

What do they weigh?

Very interesting design with the 4-sided extrusion. Could you share what the weight is per drive module?

The first is of the majority of our 2010 drivetrain components. Impressive just because of sheer quantity.

The bearing mounts are cool because we 3D surfaced them in the machine. Previously we were hanging a long bar out the side of the vise, machined the contour in from the side, then sending a kid to chop the semi finished part off the raw bar so that the backside could be machined. Switching to the 3D surfaced part eliminated all secondary handling and allowed the parts to get done way faster.

The rest of the pictures are of my favorite part I've ever machined. It was the yoke that held the wheels for our grabber onto the end of the grabber arm in 2011. It was a pretty subtle part when looked at on the robot, but it required a ton of machining and looks really cool on it's own. I like it so much because everything about it came out perfectly, when I was worried that some features wouldn't match, that there would be chatter on the inside walls of the part, etc.

What was this? 40 wheel tank drive!?!

That was before my time on the team -- we tried to do away with excessive machining...

that was 7 robot's worth of wheels.

Do you mind sharing how you made these/how much the aluminum cost you? These are really cool.

The aluminum alone should only cost you between $1-6 bucks per part. Aluminum isn't too expensive compared to the cost of the retail version of the part.

Also, great thread. Keep putting up cool pics!

Beautiful. I knew there was going to be some good stuff when Cory came on the thread.

We've milled some semi-cool things on 100 (Throwback time, like these), but the only decent looking and recent thing I had a photo of was this:



They weren't super tricky parts, but they do have a lot of very cool looking pocketing. Those parts were the siderails of our offseason intake, heavily inspired by (read-cloned from) 1538's intake.

Now, if we were allowed to submit waterjetted parts, these might fit the bill nicely:

Just so! Even his brackets are things of beauty!

Unfortunately I don't have a better picture, but these were pieces done for our 2013 competition chassis. All sparring was no-contact.

I give up. This whole image thing really isn't working out.

This was our first year with real machining resources (that arn't woodshop tools) and it went pretttty swell if you ask me.

Nifty CIM mount for our shooter, cut from a piece of 3x2x1/4
Okay, these were Akash's idea, but its still awesome.



Mmmm parts
