ot..Fanuc 18i & Angular Axis control

[MIL-TFP-41]

just wondering if anyone has played with this feature & had luck with it. The book ( user manual ) is FAR from clear as to how to use this feature. Basically, I would like my X axis to move on say a 20 deg angle...that is move the x axis and the y follows suit.....

 

Somehow I think Fanuc loses a bit of info when translating their manuals...could be the broken english, but something tells me I am not getting the full story

 

Thanks!

James,

 

Are you looking at the G68 part rotation?

I wish it was that easy. Apparantly in this control you can rotate an axis in the parameters...so even in a manual mode you can hand crack the axis and it will move on whatever angle you specify. Trying to "easily" fit a part 82" long on a machine with 78" of travel...by moving diagonally.

what about setting it up on a sign bar and and rotating your geometry to suit. another option woul be to get 2 dowel holes at known locations clock up the first call it 0,0,0 then find the second location and move your geometry to suit

James,

From what you described, it sounds like you want to use the G68 Coordinate System Rotation. I use it similar to what I think you want to align castings. Just make sure to have your spindle at the part X,Y origin before using it.
