remove stock between two mills

[Anonymous]

I have a tight corner, and i have two operations, first is a clearing using a 1/4" mill, and then contouring out the finer details with a 1/16" mill. The problem is that due to the tightness of the corner, there is stock remaining between where the 1/4 was able to pass and the contour created by the 1/16". Without doing a full clearing with the 1/16", is there a cam operation that would only remove the little bits of the excess stock that the 1/4 couldn't remove using the 1/16? 

I've circled in red the little bit i want to remove using the 1/16 using the shortest operation possible:

Looks like you used 2D pocket for the first operation?  You can just duplicate that operation, change to the smaller tool for the second pocket, and then select the "Rest Machining" checkbox on the Geometry tab for the second pocket.  This will cause it to only remove what the first tool couldn't.

Hopefully what @Anonymous proposed makes sense to you. So it's really easy to do. If you duplicate the 1st tool path it should place an identical copy right after and you need to change the tool to the smaller one, AND apply rest machining.

I think that is a great example of using rest machining because no other method would be as efficient. If you want to attach your file other can play with that to see the effect.

Thanks for showing that!

@Anonymous actually @Anonymous was the post that a solution should be applied to as he supplied all the brainpower haha... I just thought this was a great example! I'll simple kudo is good enough for haha

Thank you both very much! I thought that's what Rest Machining was for, but it seems to only work when it's in the same setup. I had two different setups for each tool, but when i combined them into one it did exactly what I wanted.

Nice you got that working...  Typically you only need another setup when you are doing another actual flip of the part OR moving to another machine. I suppose the Rest function looks at only tool paths in the current SETUP as that insures it's a continuation of a process like it is on the same machine and orientation. 🙂

yep, that make sense, in a tutorial i saw a while back, it was suggested to have a different set up for each tool you use for easy selection and export into Gcode, but in retrospect, i agree that it's not that helpful anyways.

Just curious where you saw this tutorial that advised you so make a setup for each tool. I've seen that done when a machine has no means of tool offset registration, but that's not the most common.

Also, fwiw; 3D Contour is a great operation when you are working with 3D Surfaces, not so much intended for vertical walls (Although it can work, it does limit some options) In this case, 2D Contour is more than sufficient
