Those look good, who is making them?

Is it an illusion, or are they smaller than last year?

If so, is that another move to save weight?

Here's a question- on the interior portion of the wheel, the tread holding portion- if you're just going to cut the back of the plate off, why do you pocket the entire interior, instead of just contouring the inside of the wheel? It would definitely save a lot of time but I can imagine that chunk of aluminum bashing up your wheel when you turned the block off it.

My guess is that if you do a contour, you have to make a breakthorough cut and go through a piece of wood or something that the aluminum is mounted to. Mounting the aluminum requires so much effort, especially for all those wheels, when you can just do what's done in the picture and then flip the pieces upside down and face it all off.

I'm no expert machinist; I started learning how to use CNC a week ago. Correct me if I'm wrong, please.

Interesting.. did you design to be able to climb ramps, or is that not a part of the strategy this year?

The wheels have ~.85" tread width. Wider than last year by a small amount.

And yes, the robot will have the ability to drive up ramps.

Is it worth making it out of plate instead of roundstock? It seems like the smarter way to go in terms of machine time and I am thinking of altering our machine process for our wheels next year based on these. I am curious as to how long these wheels take a piece and if it is worth the extra wasted material.

It is also more difficult to get ahold of 7075 round stock in the diameters required.
