Rest Machining between Setups not working for me

[djlunty]

I am trying to do Rest Machining and cannot get the second setup to generate a valid tool path.  I have followed the setps in the Autodesk  Knowledge Network - Continue rest machining between setups (Sep 20, 2021) but must be doing something wrong.  I do three setups, each with a different tool.  In the attached file, I do the first tool path with an engraving bit and engrave tool path.  I then clean out the cavity with a 1/8 inch cutter and then want to do rest machining with a 1/16 cutter to get into the corners that the 1/8 inch tool could not reach.  The tool path in the Setup1 (4) 1/16 Bit  does not generate  and gives the warnings "No passes to link" and "Empty toolpath".  I have selected the component "maple board:1" for all three setups and have rest machining selected in Setup1 (4) 1/16 Bit  and its associated tool path "[T11] 2DPocket (8).

What am I doing wrong or does rest machining not work for what I am trying to do?

Thank you 

Doug

Hi @djlunty 

I've had a look at your file. I don't really use 2D toolpaths with rest machining much but I'll try to help anyway.

For rest machining you do not need to create different setups. This continue rest machining is more intended for when you reposition the part and want to keep doing rest machining say perhaps flipping a part over 90 or 180 degrees to get to a different face. Also the continue rest machining function is only used for 3D toolpaths where it uses a stock model to calculate rest machining toolpaths. 

In your case you have used 2D pocketing and the rest machining is calculated by the input of the tool diameter and corner radius you input. I too struggled to get your final toolpath to work until I turned off "stock to leave" and then it generated however I do not think it has done what you are expecting. 

You may want to try using a "Pocket Clearing" toolpath I think this will give you the results you are after (screenshot below of the toolpath it generates with stock on). You can also put all your toolpaths into one setup and rest will still work - although you don't have to if you have another reason for multiple setups.

Hope this helps

Thank you for responding.   I will try the pocket clearing tool path as it seems to work for you.  As for the mutiple setups I do a setup for each cutter.  Usually one cutter does more than one type of tool path so most times less NC files created.  Not so in this case but a work flow that I have got used to.

Well I tried pocket  clearing for both the 1/8 and 1/16 bit but still does not do the rest machining.  Get the warning "

Setup4: Cannot verify that the stock is transferred from the previous setup for rest machining. Verify that the model selections in both setups are the same."

Could yoyu please send me the tool path parameters that you used. for both the setups?

Thank you

got it figured out - didn't hav erest machining selected in the tool path -----
