For the flat bottom you have do do a separate mop with the small polylines. You to do the same with the negativ 3D surface.
What I get are the toolpathes you see at the attached image 3. You need as well a roughing mop befor this finishing but this works the same way. The tooldiameter I use 1mm and I use a V-Cutter with a tip of 0.2mm. CamBam can use all this polylines in one mop for making boundariesĪs Profil 3D Method I use a "Waterline Finish" to get z-constant toolpathes. I select the first 3D object do a 3D profile mop, use a boundary method "selected shapes" and as the "boundary shape ID´s I select all the large polylines I make from the corners of the object. I use ->edit -> surface -> Plane Slize Z with a value of 5mm to get the corners of the 3D objects. Now I have two objects, a positiv and a negative. I make one surface with this values and one with the option "invert" I use a size from X 100mm, Y 100mm a Grid Stepover of 0.2 and a Z-Size from Max=0 and Min=-5 In CamBam I do -> Draw -> Surface from Bitmap Making a greyscale, but photoshop can´t use a 1bit image for using filters.

#Vectric forum pocket cut around 3d object software#
For doing what this software do you need, when working with cambam also gimp or photoshop. It has the capability of a software like photoshop or gimp and make some heightmaps. Lets have a look how vectric vcarve do this. Yes it would be nice to have a v-carve mop in cambam, but with a bit thinking you can do it in cambam also. Maybe this can be incorporated into a new MOP? The options are then set for "Inlay Start Depth" and "Inlay Flat Depth" settings. The Vectric software appears to create 3-D depth of cut paths based on the cutter profile and artwork profile width. I guess I am asking either for tips to accomplish V-carve, or a feature upgrade. I checked the G-code output and the Overcut paths are missing here too. Oddly enough, the "view cut width" shows the overcut path width - it is attempting to do the overcut? If I increase the roughing clearance to -.3" then I can get the sharp outside corners to return, but the cut path is smaller. The outside corners at the artwork level are rounded, and the Overcut paths are missing. Third attempt: Tried a side profile with 45 degree slope and -.2" Roughing Clearance. This did retain the Overcuts, but they switched to the outside points instead of inside corners, and traced to the points on the original path instead of being reduced. Second attempt: I tried using an Outside Profile MOP of the original art polyline with a negative. It appears that the Overcut feature only works at line intersections and does not detect curves smaller in diameter than the cutter diameter. I tried increasing the cutter diameter, but still no luck - the Overcuts are not created. When using Outside Profile MOP, the Overcuts are not created on the rounded corners. 2" negative offset polyline, which creates rounded corners on the inside corners. The male suface profile must be smaller than the artwork profile to fit down into the inlay pocket.Īnd it still must retain the V-cutter Overcut paths to fit correctly in the Inlay Pocket.įirst attempt: I drew a. The male inlay artwork is first inverted by using transform and rotating 180 degrees about the Y-axis. However I am having trouble creating the male inlay to match using the available MOPs. 2" using a 90 Degree V Cutter, so the cutter diameter is set at. I have gotten stumped with duplicating the method in Cambam, even with fairly simple shapes.Īs an test example, I draw a 5-pointed star closed Polyline which has both inside and outside corners.įor the inlay pocket, I am able to use an Inside Profile MOP set to V-Cutter tool and Overcut which creates the angled paths for crisp inside corners, and the remaining material will be removed using a Pocket MOP.
This method uses a V-tool to create the inlay, which allows detail that is not limited by end-mill cutter diameter. I am trying to reproduce the V-inlay technique described on the Vectric website:
