Hello,
Normally our shop programs in inverse time feed for five-axis machining. I am told that tool center point control (TCP - Fanuc) and TRAORI (Siemens) is the better way to go.
One of our techs says that programming with TCP / TRAORI is dangerous due to singularities in certain orientations. That in these positions, there are multiple solutions to achieving the same point and that the machine may pick the wrong one. The end result being that in certain orientations the spindle or table can whip around and smack into something.
My questions is. Has anyone here scrapped a part or damaged a machine using TCP / TRAORI? Is this something to be worried about? Is there someway of ensuring that this doesn't occur?
I plan to try experimenting with this on a 5-axis trunnion-type machine so it would be good to know before I break something.
