3D Printed Tool for Machining Electric Vehicle Motors | The Cool Parts Show #39

Cutting tool maker Kennametal used additive manufacturing to answer a machining challenge in electric vehicle (EV) production. The motor housing of an EV includes a large, precise bore for the motor’s stator. Machining this bore rapidly calls for a large-diameter tool - potentially too heavy for the machine tool intended to use it. Enter additive manufacturing! Kennametal engineers designed a large, lightweight boring tool made through laser powder bed fusion along with carbon fiber composite.

How has this channel not blown up, like this the stuff I like learning about!

[@AdditiveManufacturing]

At the risk of sounding like a generic KZbinr, like, subscribe, and share it around! It really helps us out. Thanks for the support, we’ll see you at 10k!

[@scottetling3887]

Congratulations to team Kennametal.

[@iamthepeterman54]

What a great application! Great video AM!

[@sankalp3513]

Fantastic use case! Lightweighting, part/process consolidation, and topology optimization all demonstrated.

[@fadilojifinni9708]

It would be really nice to see this tool in action 🤩

[@divineikegod920]

This is great...nice!!

[@Niamato_inc]

Thank you for this one. More of automotive printed stuff.

[@AdditiveManufacturing]

We're glad you enjoyed it! We have a couple of other episodes that touch on 3d printing automotive parts. If you didn't catch them yet, here they are: 3D Printed Brake Rotor: kzbin.info/www/bejne/emLTnImciruja5Y 3D Printed part on a Ford Mustang: kzbin.info/www/bejne/iqSocpKjaNd9nNE

Here before 10k! Keep ‘em coming!

Seems like a great application for Generative Design, since the loads are known. I bet they could cut the weight further.

[@gitss7367]

hmm the carbide cutting teeth are mounted with bolts on not silver soldered like most carbide tipped cutting tools. interesting

[@SuperYellowsubmarin]

Well, like 90% of indexable cutters meant for production which enables the tips to be quickly changed when they wear out.

[@Stasiek_Zabojca]

What type of industry are you talking about? If you talk about simple, small tools like cutting saws for example, yes, they are soldered. But in CNC machining pretty much all tools with carbide inserts have them screwed. Milling tools are expensive and are not single use and you want this inserts to be fast and easy to unscrew, rotate or replace and screw back in to continue working again. Especially if tool have 20, 30 or even more inserts. Time is money.

big deal, I made one of these in my garage with a file & hacksaw

[@othoapproto9603]

Please, let's find a new word to replace "Light-weighting " How about "demassing" or "un-mass"
