Here comes my best tips and techniques for #surfacing a wooden board on the CNC - what to think about, what bit to use, speeds, step over rate etc... I have an AVID CNC machine, however the principles would apply to whatever your setup is like

Really brightened the day to watch your cnc in operation. Love the cam clamps.

@wolfgangschmidtke8023 Год назад

Hallo Linn wieder und alles prima geklappt danke für deine Einladung und alles gute und tschüß 🥳 aus Düsseldorf Germany

@MCsCreations Год назад

Great tips, Linn! Thanks! 😊 Stay safe there with your family! 🖖😊

Hey Linn, while I'm fortunate to have access to a 4'x8' CNC with a vacuum table, for those who don't, it might be a good idea to delve into some of the details (pump manufacturer and model, the various components, method of securing the vacuum pods to the table, best practices and limitations, etc.). Thanks, as always, for creating and sharing such wonderful content. Be well.

Nice work on the slab surfacing I am running a 5" cutter at 8000RPM 250 IPM .1 DOC Slabs come out perfect then they are sanded with a CNC Floating Sanding head Total time to process a 2 x 4 foot slab is about 20 minutes sanded to 320 Grit. What you are doing is the best way to flatten a slab. I do both sides to equalize stress in the wood. Well Done

The way I learned to use one of those surfacing bits was, make the cutting area larger than the actual part needing to be surfaced by double the amount of the diameter of the cutter in the length and by the diameter of the cutter in the width. So a 1 1/2 in. cutter you would add 3 in. in length and and 1 1/2in in width. As those cutters do not cut in the middle of the cutter, you would want to start off or the edge. Then you would set the pocket tool path to raster making it always cut with the grain of the wood, as you might get tear-out when cutting across the grain.

If I had one of these things I’d never get anything done as I’d be playing with it forever. :D Also: .01 is 1 hundredth is it not? So a .001 difference would be a “thou”(santh)? Keep up the good work!

@w.thomasphelps2175 Год назад

definitely 5 hundredths not 5 thousandths

If you wanted your final part thickness to be 0.500 inches, how would you setup your job for that?

@Gustins85 Год назад

Nice job! Just wondering - why don't you just set finish depth in vectric to whatever is needed and add multiple passes at 0.05 inches so you don't have to come back and edit it after each pass? Or other option - set new "0" for Z axis after each pass and rerun the same gcode? :)

@bitsurfer0101 Год назад

Does that set the final thickness of the part?

Is the presentation for a specific purpose, as it's all over the place and not for beginners. It might be interesting for other woodworkers.

@TheMonkdad Год назад

Does this CNC provide a finish fine enough for basic sanding? I built a flattening rig that uses a 2” router bit, 3hp router and stainless rails and ball bearings. It’s manual but similar to a CNC flattener. However it leaves a slight scalloped finish which is too rough for basic sanding but requires a trip through a wide planer.

@darbinorvar Год назад

Because it's a cnc you can set how you want to do the passes, better = a lot longer time, otherwise you might get swirl marks. But in general the finish is pretty perfect.

turn it around Aspire by Vectrik :)

Det låter lite "swenglish" när du pratar😊!

Vectric by Aspire? :) It is Aspire by Vectric :)

@darbinorvar 8 месяцев назад

Sorry! Brain freeze, somehow Vectric by Aspire has gotten stuck in my brain even though it's incorrect!

@pinterelectric Год назад

I would spend hours with a belt sander

@HdtvTh Год назад

I mean it's interesting, but only if you are in to CNC as a specific thing, it's kind of slow, quite a bit slower than proper use of hands planes, and very much slower than industrial woodworking machines, and the price of a good CNC kind of enters that category, and you still have to sand or plane it smooth after. So I guess it's not a good idea to rely on a CNC for flattening wood.
