O/D Turning in X4

[albertamachinist]

Hey guys.

 

I'm new to this forum so hopefully I describe my problem in the correct way

 

I have roughed a long stem with numerous diameters to about 0.050" above size to allow for stress relief.

 

I now want to machine to finish size but I can only add a rough stock size as stock recognition. Is there a way of telling mastercam that I want to start at 0.050" above all diameters and not one generic rough size?

 

Thanks in advance

Mastercam ?

Lathe Rough between any two boundaries.

Try this…

I did this using X7, but I believe that it was the same in X4.

Do an XForm - Offset Contour to create the rough stock boundary.

Now when you go to chain a Lathe Rough toolpath, note the sequence –

If prompts you to ->

“Select the entry point or chain the inner boundary.”

Select your finish boundary and end that chain.

Now it prompts you to ->

“Select the outer boundary or select the retraction point or select done.”

Select your rough stock boundary.

This will do Z axis roughing passes, without cutting to much air.

 

If you want to “follow” the profile when removing this material you can do that using a Lathe Finish toolpath by setting the Finish stepover and the Number of finish passes.

(On the Finish Parameters tab a page).

Yes you can. Make a Solid and then use it as the stock.

 

BTW. Welcome to the Forum.
