Mechanical engineers and machinists, is this animation actually helpful? Would you recommend it to a ME fresh out of school?

You’re conventional milling when you could be climb milling

Hmmmm… Fair.

Don't forget to explain why you chamfer outer edges and fillet inner ones

Great points.

It's good stuff to know. You should also explain climb vs conventional, ramp vs plunge, and I think sizing the inner wall radii >15% larger than the standard tool size is worth an animation (3-sided contact has caused me a lot of finish problems)

Great suggestions!

helpful for showing why square internal corners cost a fortune

I like it. Pair it with a page that allows inputs to check for compliance with the rules by adjust material, bit, and dimensions and you have a good sanity check.

Learn by breaking expensive tooling - it’s the only way

Ha ha! Fair.

Yes. Add a 4th animation for climb milling and it’s an excellent illustration on how vibration chatter can affect finish, among other issues.

Pockets can be as deep as you want, just don't expect a .06" radius in the corners 4 inches deep.

should also do one on cutter engagement (benefits of "adaptive" strategies) and then of course more general feeds and speeds consideration (surface speed, depth per tooth, chip thinning, conv/climb etc).

That would be useful, for sure.

Seems helpful for mechanical cut understanding. I'd only wonder about the exact sizes of the tools

No, besides the fact that parts are deceptively wrong, it will not give MEs a "sense" of DFM or materials that come with machining

I would show this early in school not after, as a general introduction to the concepts. I would expect a Machinist coming out of a school to understand that tools can't cut square and to understand deflection.

The animation can help a bit. But in my experience, you see this in the workshop. I’d rather send them to the machines than have to explain off a board the parameters such as plunging depth, feeding speeds, flukes, etc. What could be interesting…

True.

That side cut animation is whack, unless there’s a new method of side cutting where the endmill rapidly moves in and out so it’s always pushing on the floppy wall. Also, super inconsistent animations, one shows actual cutting path the others just show a floppy bit and then a floppy metal. 6/10 for the animations, concepts are decent

People learn in different ways so put it all out there

Will do 🫡

I appreciate you sharing

During University covered by the Machining-Shop or CAD course.

not really

Honest.

I think it's fine. most of this stuff is kind of intuitive if you've worked with tools before, but the animation shows why if you're a wrenchlet

Oh 😯
