Newbie- Corner rounds

[bartL]

Hello,
I'm quite new with pro/mfg but I have a lot of experience with Pro/e.
Since I'm using it I can make some toolpaths pretty easy with different type of end-mills, except for the corner radius tool.
Does anybody know what kind of NC sequence I need to use for this tool. I've tried them all (like profiling, finishing etc.) but every time I want to select this tool it says "tool not valid".
Anybody who can help me?

Thanks,
Bart

Not completely sure about Pro-M, but in the past, with older cam systems, any tool that had intersections with normal vectors would be 'undefined'. I'd just define the tool like an endmill whose diameter is the pilot dia, then all you'd have to do is make sure the depth is correct.
Good luck.

Hi Bart,

No need to define any special shape tools. Just use the minor diameter (the small one at the bottom) and just use the height of the tool detial as your cut depth. Sometimes these types of tools are not great at cutting. You may want to precut most of the material that will be removed, or take a few passes.

Kind regards,

Bart,

I tried and could not find a sequence type it liked. I looked it up in help and it appears to be a tool used in Expert Machinist. Look up "Top Round Machining" in help for more detail. We don't have the Expert Machinist module for Pro/MFG

Zuma,

Thanks for your reply. I do have the expert machinist module installed but it's quite different than the standard module. I've found a corner round tool but I couldn't get it working. It seems you have to create the rounds in your part with this tool too, I'm used to complete the whole part with Pro/E before putting it in a NC assembly. It seems I still have to learn a lot about Pro/mfg.

Hej BartL,

You'll need to use a trajectory sequence in which you use a sketched tool.
Just look up sketeched tool in the help and you'll see how to use it.
The thing to remember is to place a coord sys in your sketched tool. This is used to reference your geometry. I.e. the tool will follow the chosen trajectory along with where you put the coord sys in the tool. So choose a wise location.
CL Data will still be output at the tip though.

Hope this helps, J

Jonas,
Hope you can help me with another question.
I've got a surface which I want to be machined with an indexable insert surface mill. But I've got two places which can't be machined in the same operation because of two clamps who are fitted there. How can I tell Pro/mfg it shouldn't mill those pieces of the surface?

Thanks,
Bart

In the Seq Setup you go to Check Srfs, which basically tells ProE to avoid certain surfaces which you define in there. If there are surfaces present to choose do so, if not define some of your own.
In the parameters you can set some parameter like: chk_srfs_stock_allow.
Thats not the name but it's similar(don't have ProE up and running as of now)
Set that parameter to a value how much you want to stay clear of that surface.
