Vector Map Touch Trigger Probe characteristics to Minimise lobing error

Many customers are not aware of the significant lobing error on a touch trigger probe. Currently we do not 'map' this lobing error other than average it. In some cases (long stylus length and higher spring forces)  the lobing can be significant and will result in errors whilst measuring, especially when single point measuring. PC-DMIS should be able of map the characteristics and thus provide more accurate measurements. This will give us an advanced over competitor software.

Awesome idea!

I measure a lot of things Least Sq when really I should be using Max Insc or Min Circ as the impact of lobing is so great on those calculation methods.
