Fusion 360: Rest Machining Between Setups

This video demonstrates a workflow that will allow a user to export the remaining stock from a Fusion 360 CAM setup so it can be used as the beginning stock for the next CAM setup. This also demonstrates how to place the stock in the workholding, or vise, used as the fixture of the next setup.

Great tutorial. This is something I want to incorporate with my designs for a better accuracy.

Glad it was helpful!

awesome thank you

[@jairosan71]

Thank you. I will do a great use what I learn today

Where does rest machining come into the work flow? I’ve always wanted to know what rest machining is; I still do! 😊

[@3DSteve52]

Rest Machining limits the CNC operations to only remove material that a previous tool or operation did not remove. It gets its name from REmaining STock. With this workflow, I am capturing my remaining stock from Setup 1 so I can use it as the stock for Setup 2. If I don't do this and allow Setup 2's stock to be the same size block as setup one, my operations will include passes to cut material that were already removed in Setup 1. I hope this explains rest machining better and explains the purpose of this workflow.

Here we are in November 2021 and the built in feature of setup rest machining still does not work :/

[@3DSteve52]

I can say that it has been working better for me. This video was a little older, but the built in function seems to be working as designed now.

I appreciate the fact that you're trying to help us out here, BUT 3 min. into the video I begin to wonder where you're going with this; then I notice the Origin setup relative to the stock and vice (yes, I know that it's yours, and that you may do as you wish) I then I think this is nowhere near any "standard" I've ever seen. While you definitely demo'd some useful points, the presentation was difficult to follow. I thank you for your efforts Sir.

Then what is the standard you've seen? Just need a little more detail for your critical feedback

@@macmaniacal Hi Derek, first, I just wanted to acknowledge your contact (it's about 0850 Saturday) I'll look at the video again and get back to you.

@@macmaniacal Derek, first, allow me to state that I have a background in teaching, from Disney workers to MD's, served as Medical training coordinator for a metro Fire service training more than 500 personnel on my days off from my normal duties. The general mantra was tell them what you're going to cover, teach it , then tell them what you told them. First, I commend you for putting together your video, but I was confused as to the "rest machining" (and yes, I'm familiar with it). What made you video questionable to me was @ ~ point 1:30, I'm looking at the "View Cube" and its orientation, and the orientation of the vice and the work piece WCS. They did not match up. You asked what the "standard" was: typically the "Z" is verticle, "X" is to the Right/positive, and "Y" is to the Rear/positive as used world-wide in the Cartesian Coordinates System; from this we are all working from the same sheet, or axes if you will. Typical work setup would have the Left side of the fixed jaw serve as a ref. point, OR the top left corner of the workpiece (rectangular) or it (WCS) could be the midpoint if you were working on some type of "Boss" feature. But again, I do respect the fact that it's your project/setup, and that is what dictates the WCS. The fixed jaw is preferred as it is the most stable/least likely to move. IMHO the points which I noted were those which would appear to be inconsistent within your video, and virtually impossible for someone with minimal experience to follow. I did like your Mesh to Solid demo. It might help you to understand my perspective if you look at KZbin Ch. Mechanical Advantage - Creating a Fusion 360 CAM WCS. Please understand that I in no way intended to offend you. I did find some useful material in your production. Best wishes, and good health to you Sir!
