Some of them actually happened. If you want a constant Z depth with a V-bit, just use a Profile On toolpath and set your pass depth according to Dan's link. This will give you a v-groove but isn't V-carving.
In true V-carving the Z depth is constantly changing to match your image or text. If you are trying to calculate the max Z depth achieved during a V-carving, you are going to find it hard to lay out your design for that. When most people set up a V-carve design, you concentrate on making the image or text the right size for your project.
That controls the distance between the vectors. Then you select the appropriate angled V-bit to make the cut between the two vectors and not go too deep. If depth becomes a problem, you can then use the Flat Depth option to limit the maximum depth.
Not trying to find fault here, just remember you have shown a lot of interest in V-carving and want to be sure you are really trying to do what you asked. I will check it out.
Tim, What I want to be able to do, is determine the maximum width of any given vector and still maintain the v-carve profiles. I understand the flat-depth milling option, but there are cases where I or my client does not want a flat bottom, so I am constrained to determining the combination of vector width s and bit diameter and angle.
I am sure there will be instances where the specifications will just simply not work. Case in point: In the attachment, I have several simple vectors ranging from. The material is. The 1" wide vectors created a. Assuming the material thickness was specified as. This will allow me to vary these numbers and achieve the various looks the client wants within the. Not all the elements will be textual based vectors. Some will various artistic outlines that need to vary in width or depth, as a suggestion of a shape.
Another area of concern, is when I scale vectors, which changes the widths. I would like to determine how large I can scale the vectors and stay within specified parameters.
It also allows me to provide clients with pertinent information when they provide their own vector files.V-Carve Bits for engraving, and Dovetail cutters are two good examples. A V-Bit is a special purpose bit intended for engraving. They come in all shapes and sizes, but usually they look something like this:. They do a very nice job engraving, but feeds and speeds can be a bit tricky for a couple of reasons. First, that sharp point is a bit delicate and the geometry is not nearly as optimized for plowing through tons of material as a helical endmill.
Because of that, G-Wizard needs to do compensation to figure the effective geometry just like it does for a ballnosed endmill. Here is a diagram showing the effective diameter for a 90 degree V-Bit with a 0.
How can I adjust the depth of my v-carving when it is too deep or too shallow?
The effective diameter in an 0. To select a V-Bit in G-Wizard, treat it like an endmill. Once you select a V-Bit from the geometry menu, G-Wizard does several things:.
That will cause it to figure out the rpm and feedrate differently.
CNC Feeds and Speeds for V-Bits, Dovetails, and Other Cutters
BTW, 2linc is a great manufacturer for all things engraving and is one seller of V-Bits. Corner Rounding tools are used to apply a radius instead of a chamfer to the edge:.
Chamfering cleans up the edge quickly without those complications. For diameter, be sure to use the diameter of the dovetail, not the shank. The concepts are applicable to any form cutter if you think about it. Home Learn Blog. Back to Homepage.

CNC is Faster. They come in all shapes and sizes, but usually they look something like this: A V-Bit for Engraving… They do a very nice job engraving, but feeds and speeds can be a bit tricky for a couple of reasons. Some tips: — Be sure to open a slot as wide as you can with a regular endmill that is also slightly deeper than the dovetail. Definitive Guide to Feeds and Speeds for Wood.The degree point is more aggressive when new because it penetrates deeper into the ice.
The reason is that more of the weight is focused on the point. That is also why it dulls faster than the degree point. The degree point shares the load closer to the point. It is not as aggressive when new, but it will etch ice longer because the point dulls slower.
Another way to think about it is if what they were telling you was accurate, they'd be using surgical scalpels to cut down trees. You need mass for durability in abusive situations. Varying the cross section of the exposed carbide changes its performance and durability characteristics. Ice oval racing is done on relatively clean ice, usually free of rocks gravel and bare ground.
Maximum speed demands the maximum steering bite provided by a thinner cutting edge angle. Durability is usually not a problem, especially in sprint races. Thus, racing carbides use a 60 degree insert. Cross-country racers and trail riders face different problems. Wear bars must hold up through many paved road crossings, poor snow cover and close encounters with rocks. The object here is to keep the carbide from chipping and shattering.

Click here to visit the main Vectric site. This will still cut angled sides using a v-bit but the bottom will be flat and limited to the Flat Depth amount.
This can be visibly different than a design carved to full depth without a flat bottom, but may be your only option especially if you need to work with the v-bits you have on hand.
Use a v-bit with a larger included angle, which cuts a shallower v-groove. For example, a degree v-bit will cut shallower than a degree v-bit, and a degree v-bit will cut shallower than a degree v-bit.
See eg. Reduce the size of the vectors to reduce the gap. Typically not practical once the design is set, but may be one option if you have a limited number of different angle v-bits available. If your v-carving is cutting too shallow switch to a v-bit with a higher included angle, i. Tip: Sometimes you may find the best angled v-bit for your project is one you don't have.
Find out what v-bits are commercially available in your area and create tools for them in your tool database. Then use them with the Toolpath Preview until you get the results you want.

More optionsI just got into V-Carve and need some help. I know feeds and speeds and stepover are a nonstop topic among CNCers, but I need a bit of guidance on feed, speed, and stepover for a v-bit. Generic work, generic 30 degree bit. I just need some sort of generic guidance. I can learn and adjust as I go, but I need help finding a place to start. It is actually on Vcarve defaults. Other way to have correct parameters, you can create new V bit on tool database by giving all sizes for your bit, V carve automatically puts step overs and feed rates.
Keep step overs same, you can play feed rate and plunge. I forgot to mention that, practice 60 and mostly 90 degree V bits to have perfect carving. Thanks so much for the feedback Alan. That is so helpful. Good practice starts with simplicity. Timberbits usually sells bits matches generic brands. This one looks like standart 90 degree V bit. If it is Vcarve, all you have to do is check D parameters on built in V bit tool.
Thanks for the reply Alan! Does that sound right to you? Also cheers for the pro tip re Timberbits. I mean, I guess it did it but it was not liking it. Gonna try halving these values.
Cuts like a butter with no problem. You may want to lower your feedrate and plunge rate to half and have some experiment. Yeh, half seemed to be pretty on the money to be honest hey.
Just an update, looks like it was the pots on the gshield that needed a little more juice. Still doing tests but so far so good. Sorry for unearthing the thread but… Do you mean 60 - 90 degree bits are finer and create nicer carves?

I hope this helps somebody. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. I made this chart to show what the angles or degrees would look like. You should notice in the pictures, the wider the angle, the deeper the cuts are. The above pictures are a preview of the carves, using each one of the V-Bits, all cutting at. You will notice that the smaller the angle, the more detail you will get for small print lettering.
Notice the star shape, how it changes as the angle increases. So choose your V-Bits according to your cuts, if you have Vectric Aspire, do some toolpaths and preview with different V-Bits, you might be surprise. Thanks for checking out this Instructable, and I hope it helps somebody that are just getting into CNC's. Hello Dave, thanks a lot for your explanations on v-bits!
