Verify using stl from previous op as stock

[grav400]

I am working on a part that has multiple positions. On pos 1 I ran it thru verify and saved the result as an stl file. The problem is that I have the next pos as another mill group in my operation manager. When I go to that pos in the ops manager I try to verify and use the stl file as stock. What results is the stock comes up in the wrong wcs not how it needs to be oriented to run this portion of the program. I have had trouble with this in the past and just keep "messing" with things until I get it to somewhow work.

 

Can anybody here save me some time...?

 

Thank you in advance.

Hello,

 

The easiest thing to do is to use the same stock view for every machine group. Just use System Top and it will work fine for you every time.

 

Thanks

A+ to Mike's suggestion

 

Also check and understand the setting in the "System Config settings" - "Converters"- World or Current WCS for STL file creation

 

The resolution value...

small # = fine = big file = may have toolpath calculation problems ( Error-not enough memory alarms ) as too many facets exist.

larger # = more coarse = quicker regens

Thanks Grav400 I have the same problem. What about an STL from a lathe. Right now I have one that I have to use Right side and left side on the mill and the STL is backwards and I need to flip it 180°.

Hi Connormac,

 

If you need to modify the STL, you could use the Xform - STL function.

XFORM STL if necessary, it's a little tedious but it works. IMHO I usually position the part for op1, setup stock, and then make multiple c/t planes for each additional op. Save each .STL from op1, op2, etc... and verify in order.

grav400 are you running this part on different machines sense you picked a a different machine compared to using a different tool path group for the same part?

[connormac]

Thanks all I will try it in the morning.

I also use 'Xform STL' quite a bit and have never had a problem.

 

There are usually several solutions to almost any problem. Find the one that you are most comfortable with and go for it.

 

Good luck!

I don't know if anybody else has come across this but when I save my previous operation stl and then use it for another Machine Group the RED Arrow needs to be in the previous Machine Group for it to be in the right location to run the next operation correctly.

A bug possible?

[Mike S @ S4A]

No. think about it. We're beginning to flirt with events on a timeline here...whichever machine group initially defines the stock needs to have the insert arrow in its toolpath group(s)

We present a sample conical part file in training that cuts five ops in two machines;

A 2 axis slant lathe starts out - big end turning (op1), a stock flip ,then small end turning (op2). A 4 axis mill does ops on a solid which is oriented small end to left rotating on X (this is the position the lathe "finishes" at)

the three mill ops use planes created from the solid geometry. To see the whole evolution in verify the insert arrow has to be in the lathe's toolpath group to pick up the lathe's stock def....there is no stock def in the mill group...

Thanks for the explanation that makes sense now.
