I have tried various tool settings but can not figure out why this is happening.
The first pic is just the rough cut but with ‘stock to leave’ set to zero so you can see what it suppose to look like. The second pic shows jagged corners get cut on the final pass (also happens when the part is actually cut). The 3rd pic shows the same final pass but with the angle set to 45 degrees, comes out even worse, or exaggerates the problem. All 3 pictures used the same 1mm bit for the example.
That looks like the tool is dropping down to reach the final depth. You might have to create a border around the 3D image and do a final contour cut to remove the rough edges. Another way would be to cut the 3D portion to the depth where it stops sloping and then use a cutout tool to make the final contour cut.
Yes, it looks like thats happening when trying to reach the final depth, but only on the final pass, the rough pass seems to work correctly. I am trying to figure out a way to ‘cut the 3D portion to the depth where it stops sloping’ so that I can use the final pass to at least smooth out the the surface tool marks from the rough pass… the rest of it can actually be done in 2D
