VzBoT ToolHead top plate machining CNC -  

First tip I can give you, your tools are too long. Rigidity is king in machining, especially on super light weight machines like this. And the best way to get more rigidity is less stick out. Shorter tool, ideally just longer than your cut is deep, with the absolute minimum amount of the tool sticking out of the toolholder. Second, drilling is the fastest way to remove material, I would never machine a round hole without hogging most of it out with a drill, unless the hole cost less time than doing a toolchange (production, every second counts). Also, everyone wants to use carbide tooling, but HSS cuts aluminum just fine, and is more resistant to breakage in lighter machines and less rigid workpiece and toolholding. Also, you want a tool with many flutes for cutting your chamfer, gives a better finish, and since it's a very light cut you're not so much worried about chip evacuation between the flutes. You may have had the chamfer tool too deep, if you're right on the corner of the cutting edge that may be giving you that tiny burr. Looking good though, not a bad toolpath.

The prototyping benefits are awesome, I look forward to seeing more custom metal parts!

On those ops where you're boring out the smaller hole you need to set your heights to "selected contour" and select your hole top. That will keep the endmill from spiraling from the stock top to the hole top. Just an FYI. I machine parts every day. You'll get all the tricks down. Great job man👍

Congrats on the Carvera! And may I suggest checking out Datron's High speed endmills. They work really well for machines that take lighter cuts but have very high rpm ranges like this machine does.

I would recommend getting a "mist coolant sprayer" and using ethanol, you don't need much to get an improved surface quality. While also improving tool life! Even compressed air will help with this, somewhat. But not as much as some coolant would. Ethanol is a good option, because it evaporates without leaving any residue on the parts or machine itself. Also can help with controlling dust build up, by having it "clog" up at the source of the tool cutting area, instead of blowing it away from the tool and in around the machine. It will help keep it down and on the surface of the "spoil board" and/or stock material, and afterward it's loose and can be vacuumed up without a hassle of scrubbing it loose beforehand. If doing it like this, you don't need a finish pass. Based on the tooling you have, it would become shiny and nice if the feeds and speeds are set appropriately. Also that the stock material, tooling and machine is rigidly set.

Nice little machine! It changes tool-bits on it's own :O

i love watching cnc machining videos

Not bad at all! You’ll get there 💪🏻

Unless your material is super wavy, you really don’t need lead-ins that long. A ramp with a spring pass would probably be the best way to do the outer contour. I’m interested to see you work with it. I want a mill myself, but I have been spoiled by Haas VF1s and there's no way I’m fitting one of those in my garage with all my other junk. Good Luck!

Wow! Great work Vez 🙂

Try to even out the Clamping points on the outside if u want to push it a little more , but for the beginning not to bad =D

Now a tricky but sometimes easy next step if you plan to make a part a lot is having a way to drill the holes down a bit to allow you to flip the part, pin in place, and chamfer the other side.

Hey bro, Do you allow remixes of your CAD files? If I were to remix one of the parts, would I be able to put it on say printables or something like that and link to you some how?

Hey Simon, are you still using Fusion as your prefered CAD software? I am loosing my student licence for Siemens NX and are looking for an other free CAD software. I think your VCBot rocks and wanted to ask you, in which CAD software you designed it :) Would be nice to hear from you :)

Nice man

Качество обработки удручает!!

For me it looks like faster than 400% cam speed, becouse if you put video speed on 0.25 it goes too fast for alu, but that is only my opinion

bingeing nyc cnc yet? where were your finish passes?

Could all current vzbot aluminium parts be milled on a Carvers? If so, where are the files located? Thx

Super cool, but I'm afraid you're going to outgrow it very soon if you're going to make more metal parts.

Maybe it was possible to add holes to reduce the weight?

Now Rac is jobless xD

The sides look a little rough, but I guess it's zoomed in a lot.

Is this real time or how long did it take?

Vez buddy lets get you a real machine
