What kind of constrainst would be acceptable to make things easier? examples: each cut in y-z plane -- all cuts are in z and a rotary axis about x or y. This would allow probing in front of the cutter.
How irregualr is the pre cut surface? The concern her is: if one were to make a rolling or sliding hieght sensor, what kind of bad things might it encounter? A sensor to roll or slide over surface in front of the cuttong tool could be cheaper to implement. craig ScottV wrote: >>I would like to automate the cutting of objects found in nature that are >>roughly spherical and vary in radius.
