Lathe Rough Bore Z- to Z+

Recommended Posts

I am having a problem getting X3 lathe to rough bore from the chuck out to the face, Z minus to Z positive. Before I waste anymore time on this, can it be done in MC? If so, any idea what I am overlooking. Yea I know, it could be anything and everything but I have been programming lathes on MC for a few years and have tried everything I can think of. That being said I think it is a brainfart and I am missing somthing simple. Thanks in advance.

try to switch the machining direction in the tool settings

 

i also use "use stock for outer boundary" to prevent tool collision

Did you chain the geometry starting at the back of the bore and ending at the part face? (opposite to the chaining direction for 'normal' boring)

Yes, chain direction has been addressed. Local reseller could not get it going. I hand wrote it and moved on. I presently do not have the time but I would like to figure out what is wrong. Thanks again.

I've got a file I can send you to get the ball rolling....several things to consider; Tool definition options(clearance, etc...) are somewhat limited on standard tooling but the custom tool type (even as a custom boring bar)

allows you to address primary plunge and cut directions....the primary cut for this will be opposite a "standard" boring bar....

 

Keep an eye on entry/exit vectors and motion too.

 

Lastly, using a point toolpath to guide the tool into the part is probably a good idea too.

careful with regeneration as you may have to repick the points.
