Thank you very much, these two papers are indeed helpful!
TygerDawg, we're building a very specialized machine, and hoping to make it simpler and cheaper than the head-tailstock positioners available. We need only 2 positions for both tables and the supporting frame, which greatly reduces the...
Waross, could you show me how to arrive at the HP you specified? I can't seem to be able to wrap my head around the conversion problem, my moment of inertia is 260000 lb*in^2 (one table), and it would be nice to have the table flip 180deg in less than half a minute. I tried three different ways...
Thanks for your replies, gentlemen!
7another4, you got it almost right. The tables don't have the welding equipment, only the positioning clamps and the part to be welded. The two tables rotate independently of each other and the main frame.
I'm sorry, I don't have a picture before Monday...
Hi everybody,
I am building a rotational positioner for a robotic welding station. I am completely lost on how to tackle the driving problem - never dealt with motors aside from a class that I took 5 years ago (and failed it, the only failed class in my academic career).
I have 3 pivots, two...
