Hardcore Aluminum milling on an S3


(Neil Ferreri) #247

I took a guess on what to do based on reading a lot of differing opinions. I did use a climb cutting pass to finish the sides.

And I think I did this right after the HDZ upgrade. I think I could’ve cut deeper. I was thinking that it’s probably better to engage as much of the cutting edge as possible for heat and end mill wear. I know I cut at least 3mm DOC with the stock Z.

I’d like to see what @Vince.Fab would do with that part now that he’s going faster.

I’m pretty much winging it too. When something works, I’m usually pleasantly surprised.

Same here.

Neil, ran the file you posted at 30k, 2500 mm/m same doc and optimal load, single flute .25” HSS end mill.

It was so nice to have a complete cam path to study. Thanks!

Will be cutting another with more aggressive doc.


(Neil Ferreri) #249

How’d it turn out, Griff?


(Griff ) #250

Work in progress, truth be told. Excited the adaptive worked out so well! Experimented with finishing passes with a 62 degree bullnose, not so happy with that. But, I have a baseline, only way to go now is up!

Vince, sorry we’ve hijacked your thread. Learning a lot though!!

Yes sorry to hijack your thread too Vince, please keep the good stuff coming

No worries guys. As long as information is flowing, everything is gravy

@stutaylo I’ve tried that style single flute in 0.125 and they were garbage. Easier to use a tried and true hss amana imo. Cut down the variables

I have a few more aluminum projects for this week. Trying to hold off with upgrades until paying work is completed lol.

Always gotta up the challenge


(Daniel Story) #253

Plan on using a round-over (aka corner rounding) end mill or just gonna use a ball end mill for those outside edges @Vince.Fab?


(Vince) #254

Been having great luck with a 0.125 Destiny chamfer mill and could change everything to 45°, but might go 0.250 three flute finish ball. Customer wants a few extra sets of them for his other race cars because its a hard sensor to mount easily.

How long do these HSS endmills last you? I’ve always seen comments about how they dull quickly but you use them with great results.

Is it a candy dish ?


(Griff ) #258

Hey Vince, check it out!

Mine are fluffier haha, not quite so aggressive.


(Graham Gerhardt) #259

Maybe you could open an Etsy shop and sell it - need a good product name…

Piss your wife off no end magic silver stuff…

Ha, way ahead of you there, she’s threatened to not allow me in the house after a day in the shop shod nor clothed.

I just got a call at work day before yesterday from my wife, she said no more shop till I could figure out a way to keep sawdust and wood chips in the shop and not in the house. I bought a couple rubber mats with tall pips to put at the entry/exit. So far so good. Aluminum chips are a little different as they can really get buried into your soles. For that I’d recommend a pair of shop shoes that you take off , then leave a pair of house shoes just inside. Doesn’t matter how much I sweep or how good my dust collection is, I still track that stuff in, hopefully the mats will help

Awesome to see it all the bits you’ve made on the shapeoko in the final piece of art. It looks so tidy! (That’s Australian for F***ing awesome mate)

Thanks for sharing, a lot of people have learned a lot from this
