Model Rest Area Clearance used Unsafe segment removal result Tool Damaged

[peter.hsiao]

Toolpath H03 D26R3.5 used Unsafe segment removal.

Actually here still have stock.

 Next use Model Rest Area Clearance Calculate, Rest option choose toolpath H03 D26R3.5 used Unsafe segment removal, Calculate produce H07 R5_Error toolpath, Can see picture actually here still have stock, but There is no path result Tool Damaged.

Please give me assistance on how to solve this problem.

Hi Peter.hsiao,

Thanks for posting in Autodesk Community!!!

As I see your attached PowerMILL project in 2019 version, the model is missing from the project. Can you please upload it again.

Hi Peter,

You cannot use Toolpath for Rest Machining, because PowerMill don't see your previous toolpaths, just the one you defined in rest machining area. Thats why you have collision. You need to do rest from stock where you insert all previous toolpaths.

You can use Toolpath for Rest just if it is one toolpath before this one you want to machine.

So, this have nothing to do with Unsafe segment removal.

Hi Peter.hsiao,

Thanks for the timely response.

I am thoroughly studied your supplied PowerMILL project and concluded that something is mistaken by you in the project. As I have seen, the toolpath name - H01 D50R5 was already manually edited. That's why the rest machining toolpath not detecting the area to machined properly. I have edited those toolpaths, added the name modify in the prefix of toolpath and getting the desired toolpath as per your need. Please refer to the revised project. Hope this helps you to resolve the issue.

I absolutely agree with @rdbojan.......use a stock model for rest machining.

However, you must maintain your stock model correctly.

Meaning, if you edit a toolpath that's been applied to the stock model....then the stock model should become invalidated and require you to recalculate it before it can be referenced to another toolpath.

On the other hand...if you make a copy of  a toolpath that's been reference into a stock model,  and then you modify that toolpath....the stock model would NOT be updated correctly.

Personally, I've never trusted rest machining by "toolpath"
