How do I set the Cut Depth when v-carving?
The V-carved Toolpath is unique because there is no way to set the Cut Depth. The toolpath requires a closed vector shape and will move the v-bit as deep as required to machine to the two vectors on either side of the bit.
The wider the gap between the two vectors, the deeper the v-bit will cut.
The narrower the gap between the two vectors, the shallower the v-bit will cut.
The higher the included angle of the v-bit, the more 'pointed' it is and the deeper it will cut.
The lower the included angle of the v-bit, the 'flatter' it is and will cut shallower
Note: As long as you have the Material Thickness accurately set in the Material Setup, the program will warn you if the depth of the v-carving will be deeper than the material thickness. How can I adjust the depth of my v-carving when it is too deep or too shallow?
If your v-carving is cutting too deep you have a few options:
Easiest solution is the use the Flat Depth option near the top of the V-Carve / Engraving Toolpath form. 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 90-degree v-bit will cut shallower than a 60-degree v-bit, and a 120-degree v-bit will cut shallower than a 90-degree v-bit. See eg.1 below for different angle V-bits on a 2" circle profile.
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.e., more pointed.
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. Now you know exactly which v-bit you need to purchase to complete the project.
