Hey all,
I have a 2003 KIA SKT21LMS with a Fanuc 0i-TB, and I'd like to start using the subspindle. I have two use-cases in mind. One of those being a conventional slug transfer application (I *think* I understand how to do this), and the other is as a support for long parts.
I don't know whether I'm best off getting a spring loaded center or just leaving some extra stock and chucking on that for the turning of somewhat longer parts, but either way I would like to be able to monitor the servo load so I don't burn up a servo/drive or ruin parts.
This brings me to my problem though- on the servo monitor screen, I can only see X, Z, and Spindle 1. I have a B, Spindle 2, and milling spindle that I would love to be able to keep an eye on. Is there a parameter to enable display of the load on these additional axes?
If I can't see the axis on this screen, does that mean I can't use G31 torque skip with it? I'm tempted to program a slow feed move with a low load set to test this, but I figured I'd be best off asking here first before breaking something.
I'm also not sure how to program the subspindle efficiently; Should I use a macro variable to control the position, assign it a WCS, use absolute coordinates, or something else? I don't have (as far as I know) an M-code for simple subspindle turning like I know some HAAS and Okuma machines have, and the manual doesn't even begin to explain how it's expected to be used. I'd be interested to hear everyone's favorite subspindle workflow.
In any case, I get the feeling that I'll want to write some macros or subprograms to simplify operation.
I'm programming with fusion 360 CAM, but I am comfortable editing my post to make it cooperate with whatever I settle on for workflow. I can also just do a Manual NC passthrough to "hand code" from within CAM, so anything should be fine.
