Olá meu amigo!
Alvaro, what I think that may reduce the error is to measure thereal times,get an error factorbetween the real result and the Pro/NC result and then apply global parameters and global relations in the process manager toforce Pro/NC to output estimatedtimes closer than the real ones.
I´ve some material here I´m willing to share. Please email me at daniel dot santos at liebherr dot com and we can find out a manner to figure out how to solve your issue.
For the time being, that´s is my only guess to handle these issues... if everyone else has other ideas, pleasekeep it coming...
