4th Axis cam

Hi Everyone, I have been trying to tool path the attached and am having problems. I would like to not machine the bottom of the handle off the stock. I would like to cam it for a mill 4th axis. I am reasonably new to fusion and really struggling with this one, any help would be greatly appreciated

Extend the handle a little in your model, because I assume your cutting it off anyway. And create a boundary sketch to contain your 3D path. Machine one side, then rotate the 4th axis and machine the second side.

 

Fusion 360 only supports cylinder wrapped 2D paths at this time.

This part doesn't really require a 4th axis to machine but I assume your just using this model to learn. In reality this part could be milled 2D. :winking_face:

 

I attached the model that mills one side and then flips the part 180 degrees and does the second side.

Awesome, Thats what I was missing I hadn't thought of containing tool path with a sketch. Can you give me an example of 2d wrapped tool path , I have watched every video I can but still struggling with my model.

Appreciate the help as I have spent hours playing around with it

I've attached a simple model demonstrating how to wrap a line of text and mill it.

Not sure what I am doing wrong but I keep ending up with this result. I have made sure that the stock is dialed in 100%. It must be in the cam setup?

I am using my manual 4th axis

After your roughing passes (adaptive clear) you need to finish with a ball mill using an appropriate finishing strategy like 3D parallel or contour.

Yes but it will not finish one side as it is off set, Attached is the file, The 4th is dialed in with a dial indicator and is parallel with X

Are you certain your stock was on center with the rotational axis? In the model your origin is the center of your stock. Not sure what offset your referring to. I see you limited the depth per side by 5mm but that's all.
