Lab Time Fun

Today, the group worked on double checking all the drawings and the Mastercam files.

At around 10:30, we started making our first mold for the orange cavity.
When we met with Dave to go over our tool paths, he suggested that we face the surface before we make the cavity for the mold. Additionally, we needed to change the direction of the chain. Oops!
We added this and updated the code on the dropbox.

Then we started making the mold! Yay.

Machining the mold!

First mold of the 2.008 season!! Almost done, minus the runner.

The only thing that we noticed was that there is a little bit of a dotted line along the inner edge of the cavity. 

Dave said this was because the tool we used for the finish was 5, which isn't as stiff of a tool. The divots were due to the tool vibrations as it was finishing that inner radius. He suggested using tool 10 for both the rough and finish cuts, but then we would have a larger radius on the inside of the tool.
