AR2 from Italy

Hi all, here are my first steps to the robot costruction. I am also a mechanical hobbyst so I will realize all

the alluminium parts.

Thank you Chris for your great job.

Hi Alessandro,

 

Wow, you're going to make the parts yourself! Please post pictures of your setups; I looked into this and studied the type of fixturing I'd need to make these parts on a 3-axis CNC and realized it'd be difficult without a 5-axis machine.

 

Still, your J2 housing looks awesome! Definitely would like to learn more about how you approach each part.

 

I did a quick study before I started my build about how I would cut these parts with a 3-axis CNC, manual mill, and lathe, I can post the spreadsheet somewhere if it would be interesting to you.

 

/Mitch.

Hi Mitch,

here is an example.

I make only one part for me, so I am using my cnc milling machine into “semi-automatic“ mode.

Congratulazioni. Lavoro fantastico

 

Thank you for sharing. I particularly like the surface finish of your parts.

 

Would love to see more videos and photos if you have them.

    pmf's AR3 Build from Massachusetts

    Discussion 
    Parts acquired, now to build... I have already printed the covers and have started on the electrical cabinet. All of my screws and smaller "stuff" is located in the Akro-Mils Bins and wringing and larger "stuffs" is in the clear bucket.

    hello AR people, My name is corey i started in on my ar3 over our christams shut down. i have some education in electronics and automation, I am a manufacturing engineer (fancy machinist) during the day. my specitalty is mill-turn centers and swiss style lathes up to 8 axis, although i do program and setup a 5 axis mill that the milling department hates. Progress: -Most of my hardware is in -Motors are in -My aluminum kit arives monday, i plan on tumbling them down to a matte finish and sending them out for annodizing. i realized after printing a few components and reworking them i was going to end up time and money ahead going the aluminum route. - Covers are about half way printed, i was using the covers as a test on the makerbot i had at work that was non functional, after firmware and a few mdifications it is actually making some nice prints. now most of the prints will be feinshed out on my ender 3 pro -Electronics- boards are in but i plan on using a larger enclosure, and integrating the cell controler, so i dont need a stand alone pc. Also i plan on using zip-port connectors rather than the aviation connectors so i will end up with 1 maybe 2 connectors on the robot. Also i havee been very impresesed with some of the main board concepts i have seen in the forums and may go that route but plan on conventional wiring to get going. I am building this robot as an introduction into robot kinematics and a study in process automation, my first planned implementation is to automate a chamfering operation that involves chamfering a rectangular block on all 12 edges. long term goals include using robots as machine tenders to pull parts from mills and lathes, also i have identified some assembly processes that could be automated.

    Nothing exhaustive but I’ll try to include useful stuff as well as general progress. Most of the 3d printed parts ... not sure I like the colors but it was the least offensive of the filament I had sitting around
