"Multi-Axis > Rotary Pocket" - Rest machining does not seem to be cooperating for me :(

[tabone_6]

Hello,

I am having trouble figuring out why I am unable to rest-machine with Multi-Axis > Rotary Pocket operations.

The majority of the material is first removed with rotary pocket with a 1/16" 2-fluted end mill. The second operation is also a rotary pocket operation with a 0.0240" end mill selected. Both operations are within the same setup.

I have tried using method: Enter simulation for the first rotary pocket operation > forward to end of TP > right click > Stock > Save Stock as STL > Load into design and use for stock selection under a new setup. This does not seem to be working for me either.

I have also tried simply selecting "Rest Machine Enabled > From Previous Operations" and the generated TP is still showing cutting moves for already removed material.

I was wondering if anyone had any thoughts or suggestions on this issue?

I feel like I am missing something right in front of me 😞

(Attached is a f3d., snapshot of operation 1 (which is correct), and a snapshot of operation 2 (which is providing me a toolpaths with cutting moves for material already removed by the first).

Operation 1: Rotary Pocket (Working correctly!)

Operation 2: Rotary Pocket with rest machining enabled (not working).

no need for stock model if using Prev. Ops.

I didn't look for sure, but I think it's because your .02 stock to leave also applies to the floor. I'd also only be leaving about .005-.01 if this is wood.

The Rest machining is working just fine from what I can see, Have you actually simulated the part to see what's happening?

@tabone_6 

I have just turned off the Rest Machining in the first operation (Not needed) and also turned off the Stock to leave, seems to work fine now.

As @programming2C78B  previously said the Stock to leave is causing the floor of the pocket to be toolpathed again, see attached file. Hope that is of some help  🙂 🙂

Thank you so much again 👍
