SUPER Smooth Finish With ZERO Sanding! CNC Tutorial

In this video, I use my desktop CNC router and a stepover finishing technique that will virtually eliminate the need to sand my project. This technique will save you a ton of time and give you smooth finishes!

In machining, this is common practice. It's much easier to get accurate parts when your finish pass is like .01" because there's a lot less tool pressure. You find that your depth of cut, speeds, and feeds all vary depending on material, but in general, when roughing, you have lower speeds, higher feeds, larger depth of cut. For finish passes, higher speeds, lower feeds, minimal depth of cut.

I’m new to cnc. I’ve been doing it 6 months and really appreciate this video. I just tried this Technique and WOW did this work. Great video. This will save me a lot of sanding time.

Thanks for the video. This is so true. It’s so easy to get into a mindset that the the CNC needs to produce the piece as fast a possible. Only then to realize you introduced an hour of complicated sanding to make things perfect.

Great video. Thank you for explaining that a little clearer. I've been looking for ways to gain time back in the shop, and this is huge. Thank you.

Most YouTube videos are made on the level of the person making the video.
Meaning that if you have 10yrs experience with a CNC then you make very advanced videos. It's great that Andy Bird takes the time to make some videos like this to help less experienced CNC users get the best results possible out of their CNC.

I was aware of the idea of a finishing pass, but the quick reference to the sizes of the tool and stopover was very helpful. Thanks!

What a Well Done Educational Video!!!
So Neat To Know! Thank You!!

Holy cow - I totally forgot about final finishing passes until I saw your video. Using a bowl bit (or a round over bit) with 10% step over and very shallow final pass in the key for me. Thanks for reminding me.

[roygault]

Thanks for the info. You have helped me immensely.

I'd recommend doing the last finishing pass twice. Wood compresses much more than you think and doing an extra finishing pass can make a difference.

Thanks! It's so simple! When you started discussing it, I was like, why the hell didn't I think of that?

Thanks Andy This new tome I will use on my next project "Daveyfriend Wood Designs"

[DerekMcCrone]

Very helpful!!

Any tips for doing a finishing pass on a contour cut in Carbide Create?

Great video! More cnc tip videos please 🙏🙏🙏

I have been doing something similar, my final tool path is .035 and I usually speed it up once it is going.

[MicroFourThirdsCorner]

I've been doing it this way for a couple of year now and generally it works well, though better on some woods than others. I do still like to sand to get that final critically smooth finish on some special pieces.

I have a really good result with a .25 end mil bit for roughing. then a .25 ball nose with a 35% step over. This has turned into my one of my fav bit sets a .25 end mil then a .25 ball nose then a 1/32 tapered ball nose 8% step over for the tapered ball then i use a 45V bit to clean up the edges. But this is for high detail. Rest Machining method has became my friend.
