Creating stock from a forging in X2

[trumper777]

I have tried to import .stl files for stock and it shows up as stock, but for some reason my tool paths do not look correct at all.

 

Is there a secret I am missing??

 

Thanks for any help you guys can provide.

What are your tool paths doing that is not correct?

Make them solids and put them on a level. When you do the verify grab the solid in the verify. If you are using the .stl as stock for a toolpath I can not be of much help.

Well let me start at the beginning. At our shop we primarily use forgings and do not start from bar stock or flat stock. In Mastercam when i start to write a program i go to click the create stock. I pull an .stl file for my stock option. (instead of rectangle, cylindrical etc..)

The material shows up on there but I can not machine on it. is there a way I can draw the stock to simulate my forging or is there any other way?

I have found that when I use an .STL file, it just gives me the periphery/countour of the stock and does not use it as for verify. For verification, bring in a solid (it will automatically import to a different level) and go into the verification, pick the yellow file folder with the exclamation on it, then pick the solid radio button and then the arrow to select your solid model. Save the file before doing this as sometimes it will delete the solid.

We don't start from a forging, but start from billet and go thru several steps. At each successive step, the model from the last step is used as the stock model for verification.

Sometimes, on the parameter screen for the solid selection, you may have to unselect Truesolid. Ours works sometimes and otehr times it doesn't.

Also look to see wether you have Translucent Stock selected on this screen.

 

Welcome

 

Hope this helps!

Use "Surface High Speed Toolpath" Rest Roughing toolpath type or Rough Restmill toolpath. On the Rest Material Parameters page check the CAD file or the .STL file option. On exit you will be prompted for the file to read. HTH

Is your stl stock just not in the right place for verify? If so, open the .stl in mastercam, translate it so it's super-imposed on your actual part. MAKE SURE VIEWS ARE SET TO TOP WCS, and save .stl from there. You can move the wcs all over the place for machining, and see all sides verified in one shot, but it's critical that you save the .stl in top.
