These Nomad videos are awesome and much appreciated!

OHMYGOSH an actual real video in my feed. Next April 1 I'm going off the grid. Thanks Winston.

Hi Winston.

Cast acrylics is also less brittle as extrudet material, but extrudet has a more even surface and a 10mm sheet is 9.9mm to 10.1mm, where cast can vary from 9mm to 11mm.

And you can minimize chips wrapping around the tool by speed up when going Z down(about 3000mm/min or 120inches per minute), an if possible, combine it with a ramp down.

And at last, I always try to use only Single fluted tools, so the chips have more room to get out of the toolpath.

Do you provide a printed list of recommended speeds and feeds for different cuts? Like a collection of the screen pop ups in this video. Thanks Tom

[Stephen]

Not to mention you want to be careful with the chips clogging your v-wheels as they are incredibly static after being chipped off and will stick to the aluminum extrusions very quickly

1:41 What are your speeds and feeds for the finishing pass? How much stock are you leaving during roughing?

[elalconcel]

Hi Great Video!!! Do you have speeds and feeds for Vbits on Acrylic?

[LG-role]

Can you make a video for feeds & speeds when Vcarving oak? I keep getting a horrible rigid finish all of a sudden

[officeroinks]

Where can you source acrylic or do you make it yourself

[davenicholson]

Interesting video 👍🏻. Where can the cast acrylic be purchased? I can’t get it in a decent thickness here in Australia.

[manthanmohite]

What should be the grade of makrolon for high machinability?

[louiejayjayme]

hi!, I'd like to ask if you could go lower than 10, 000 RPM? for example like 4, 000 RPM? would that change the Feed rate, Depth of cut, and stepover?

[robertlawson]

Thanks for all the great videos, Winston. Hey, why not a video (or two) about Amana's Single Flute end mills? They work perfectly for both plastic and aluminum.

Oh and yes acrylic stinks when cut too hot. I remember cutting pieces on a table saw and the odor was horrendous

[kevincoates]

Im machining acrylic today for the first time but those parameters seem super low. .02 doc? seriously?
