Mastercam Lathe Stock problem

[pip]

I am new to Mastercam Lathe and have been trying to adjust the stock on a facing operation.

Could someone please explain how this should work. Do I need to define points on my geo, or can I just graphicaly select a point to adjust stock.

I could just adjust my geo to the inner diameter, but I would like to use the stock function.. All help greatfully accepted.  Thanks.

As long as the stock and part geometry are properly defined, you shouldn't have to define anything, just select "Use Stock."

 

Assuming you're already doing that, where do you think the stock is causing you problems?

 

If you have a ton of stock on the face, Mastercam has never been particularly good at recognizing that, so Canned Rough is often better there.

 

If the tool isn't turning down far enough in the X ( toward the bore / drilled hole ), which sounds like it might be the case, increase the Overcut Amount to bring the tool further down the face

Use margins if you want to leave stock for facing.

YES! Didn't think about that, because it is just automatic, but you're absolutely correct. If you're using bar stock, MC needs to know that there is stock on the face. If you're using a casting / pre-machined blank, the stock should already be there (chain it).

I use the position along z axis in the stock setup for the extra stock that needs to be faced and this works pretty good.  then mastercam sees it and when you face it off you can pretty much go with the default settings and let it rip. after you save it to the file you can go edit your facing settings to your liking .

I don't like the face t/p.   I use regular roughing and change the direction of the cut in the rough direction/angle drop down.  

As far as the stock,   I always draw my stock for the first operation, I use stock revolve then lathe stock preview after I finish the first operation and use it for the next operation and repeat.
