    摘要: A machine tool is controlled through a process incorporating the steps of (1) measuring geometric and thermal errors with accurate instruments, (2) creating a global differential wet model of machine tool position, and (3) using this model to control real time compensation of machine tool operation. A controller modifies encoder-type position feedback signals used by the machine to compensate for geometric and thermal errors in the manner dictated by the global differential wet model.
