How to Burn Challenging Features | Learn to burn

Just because features are simple doesn't mean they are easy to machine. In this episode of Learn to Burn, EDM expert Steve Michon introduces tips and tricks for burning challenging features.
The simple, but challenging features covered in this video are as follows : making an electrode, along with machining vector burns and sub gates. The time stamps are as follows...
0:48 Building an electrode on a Bridgeport mill
4:07 Tricks to create a square shaped burn
7:17 Creating the square burn by 2 staging the electrode
7:57 Orbiting techniques
9:03 Orbit patterns in action!
9:25 Halfway point of the orbiting process
10:10 Final product of square with sharp corners
11:26 The design process of a challenging job that required very sharp corners
13:55 Check out that design example live on the machine
14:33 A low cost solution to vector burn sub gates
16:00 Sub gate tooling
17:04 Burning a sub gate in a block with a vector burn
18:39 Underwater footage of vector burn
18:56 Complete sub gate
Stay tuned for next month's episode!

That 2 stage electrode part looks like a geometry nightmare 😮 great job !

[@paulmace7910]

Awesome! It’s absolutely amazing what can be done with today’s tooling. Thank you for sharing.

[@zerotolerancecnc]

It sure is! Thanks for watching

[@rdc02271]

Thank you for another amazing, informative video!!

[@justinmoritz6543]

Learned a lot from this video!

[@jklhu]

I work for snap on tools in the tool room. We have a wire and sinker edm’s. Both are Mitsubishi also. We have 3r set up in the sinker and I want to make a fixture for a 3r setup in our wire and your video has been helpful!

[@nikolaiownz]

You have a fantastic attitude towards work. Use whst you got 👌

[@zerotolerancecnc]

Thank you! Use what you have and always give 100%

This is a very interesting series, thanks for taking the time to do it. I wont be doing any edm work but it is nice to know a little about it. Charles

[@zerotolerancecnc]

Thank you, we appreciate it & enjoy making these videos. Thanks for watching!

[@sangmanh6991]

Thank you for sharing.

Always good content

[@samuelaylmore9281]

These are really helpfully, would you be able to explain the parameters you would choose for a particular burn. For example what peak current youd run. Thanks for the advice.

[@zerotolerancecnc]

Thanks for watching! Typically we take the contact service in 2D, if it has draft we add the draft but we enter all of that into the control and then the control gives us the corresponding current. For older machines that I learned EDM on, I would start with a low current and adjust it until it sounds good and making good progress. The goal is to walk away from it and let it go and not have to worry about it.

@@zerotolerancecnc that makes sense ive kind of been trial and erroring my way through. The machine im using is a manual with a fuzzy control. Looking forward to the next instalment 👍

[@oscarmedina-rr3rw]

Hello, could you advise me on how to erode a gate at an angle on a MITSUBISHI machine, the parameters as shown in your video, thank you.

[@melvinverdan3586]

I want work in your shop😘

[@Z-add]

Why did the engineer design a part that requires perfect square corners?

[@cruch9]

Going to do any wire edm videos?

[@zerotolerancecnc]

Yes we plan to do more wire & fast hole videos. Episode 2 was wire EDM focused but there will be more as we continue!
