That looks shiny. I'm sure it'll come in handy during the season for those odd tooth sizes.
Have you considered getting a rotary broach to make the hex bore? What made you choose to write a program to generate the G-code over a CAM plugin for your CAD software, or a similar solution (like MasterCAM)? |

Nice!

That's quite an expensive machine. Is it used for something else in addition to FIRST robotics? Also, I'm curious what involute cutter you're using and where you bought it.

That's pretty awesome! We're looking at doing something like that when we move in to our new building next fall. Either a used Haas or something newer like a toolroom mill. Got some photos of the Haas for us machinery geeks out there? |

That looks awesome! Quick question: how'd you locate the center of the gear for the pilot hole and the broaching? |

EDIT: If you are using a lathe to turn the initial diameter, you can use a rotary broach in the tailstock to broach the hex instead of going to the press. |

You know what really cuts my gears? Those Highlander guys!
Looks nice, I would suggest making gear stock and cutting pieces off of it as it is likely to be more time efficient. Also use 7075 if you are going to be putting it on a robot, the cost is worth it. If you are not already aware, 7075 has nearly the same structural properties as 1018 steel but the same softness as aluminum. nice and strong but will wear much quicker. |
Re: Team 4499's first Homemade Gear!
Gosh guys! I'd finally got our HAAS working this month and then you guys have to show up and one-up me? :p But seriously, this is awesome! I don't think I've seen your guys new (old) VF2 in person though. I'll have to come check it out sometime. Thanks for the help you gave us with HAAS training a bit ago. One last question, I can't tell from the picture, does your HAAS have an automatic tool changer?

Here is the GitHub link for the python code that we created to make GCode.
