Hello! I'm new to Fusion360, but have hobbyist experience with CNC and I'm a pro at other 3d animation software.
I will ask my question first and then give context after that. Hope someone can help.
QUESTION: Is it possible to ramp along a surface to essentially get a finishing pass in the first operation?
BACKGROUND:
I'm needing to carve a 1.3cm geometric design into each side of a 3cm cube (A). I want to make several of these so I want the process to be as optimized as possible. I don't want to switch out tools for multiple passes for ever single side.
A
I've been successful in doing this with flat gcode generated from Inventable's Easel program (B). The blue wax and wood pieces above were created that way.
B
The issue is with the overlap of the corners, it cuts into the design on the adjoining side (C)(Click to enlarge the image).
So, I've decided that if I could get the gcode to ramp into (or out of) the material to make a bevel at the edge, I would eliminate the flat overcuts. I've created an .stl model that does just this (D) in a 3d animation program. My designs (2d and 3d) are larger than my stock so it passes fully outside of the material.
D
I knew I was going to have to up my software game to do this, so I started to jump into F360. This is as close as I've gotten in trying to do this with one tool/pass (E). It's a lot of stair-stepping and jumps back and forth quite a bit.
SETUP: My setup is a Gen 1 ShapeOko (don't laugh) with upgrades (spindle & new GRBL board) with a 1/16" flat 2 flute end mill. Since it's not a very sturdy machine I keep my speeds quite low. I also 3d printed a quick-change jig for the cube so I can just slide it in and out after each side is done.
CONCLUSION: So here's my thought. The 2d carving from Easel takes about 6 min. with two depth passes of straight cuts (with my settings). Can I get Fusion 360 to create the same passes and just ramp out to create the slopes of the bevel? Seems simple in my head. Seems like it would make a smooth finish with only one process and one tool. Again, it's not a lot of carving, it's not very deep, have a lot of these to do, so I'd prefer to do one pass with no tool changeout.
Any tips, tricks, suggestions, and help would be greatly appreciated!
