Beautiful.

Hi, can You tell what configuration are You using, as: 1) tool diameter and nº of flute. 2) rpm 3) feed rate 4) deep of cut Thanks

Yes, it'd be nice if they spec'd the machining parameters, but let's see what we can deduce: The machining produces a 300 Hz tone. If we assume a 1-flute tool: 300 Hz -> 1/min 18000 So probably 18k RPM, or maybe a 2-flute running at 9k RPM. For the feedrate: 19 seconds to do a pass around the piece, which looks around 30 cm diameter, so: 30 cm * pi / (19 s) -> mm/min 2976.2456718219093833 We do know the stock is 1.5" thick. We don't see all the passes, but it must be at least half a dozen. 1.5 inch / 6 -> mm 6.35 Maybe 4 or 5 mm per pass? Shrug. :) Calculations are in Frink syntax.

yeah, baffles me why they seem to think this is some kind of industry trade secret.

for that type of job - 21k spindel rate, 1500mm tool speed, 5mm for pass for a single flute tool - this is all you need to know for a good finish

Whats the router speed rmp if I may ask?

Fine cut. how do you hold the center piece to avoid moving at the final cut? i'm stuck on that part...

vacuum

What bit? What RPM and Feed rate?

Awesome. Question, I'd like to rout out a shape from Paulson Plus (I think it's acrylic, but it may be plastic, I don't know). Can I use a regular wood router bit to rout out a shape or will it cause tear out? Do I need a specialty bit?

Hi, great video. I would like to know what is the XY advance speed, what is the Z axis step down and what is the spindle rpm? Thank you very much.

I never understood why people 'blow' the excess waste rather than vacuum it up... I imagine the ultra fine plastic, metal and even wood particles ain't good for your lungs.

What is the feed, rpm and type brand of bit? I'm rewelding chips in material 1/4 and thicker. Thks

Hey Esteban, I personall use a 9.5mm Onsrud 3 Flute Up Spiral Finishing Bit (tool number 60-245) and cut in multiple passes at 4.75mm per pass (or less, the rule is to cut around the same depth as half the tool diameter per pass). Try a "last pass compensation" too, allow about +0.2mm bigger on the roughing cuts and bring the last pass in to the required size for a clean edge. I cut 25mm thick acrylic like this a few times a week. Feed : 2000mm/min Plunge : 1500mm/min (V-Ramp) RPM : 18000

Generally 2000mm/min, sometimes a little quicker if the chips are getting too hot and "clumping". Sharp bit makes a huge difference, try more and shallower passes with a final cleanup if you're struggling. Or, get a 120W laser! I'm doing 25mm thick acrylic on our 100W.

Marks on the side are tricky though, I usually end up with a matt finish that needs cleanup and polishing. I'd love a diamond finishing bit but at $1000+ Australian it's not an option. If anyone has tips for polished edges on the cheap, let me know too!

Kieron Lomax I've 'heard' that MAP gas torch will polish the edges. I've never tried as I didn't have the $50 to throw down to experiment, but I've read a few places that is how they polish sides

Kieron Lomax how you avoiding taper cut with such a depth? I have 40W laser and can only cut 5 mm in one pass but still laser beam is kind of cone shape

Man that's thick.

why is it not melting on the bit??

feed rate the chips pull the heat away.

It's cast acrylic. Extruded acrylic has a lower heat tolerance and it's more likely that the chips will weld back onto the material. Also, using the correct speeds and feeds solves melting.

pointless video without giving parameters. Cutter diameter, flute number, rpm, feed rate
