Abstract: In a machine comprising a spindle configured for performing a machine process in positional relation to a table, a method of operating the machine comprises fixing a probe to the spindle and fixing an object to the table. A first orientation position of the object relative to the spindle is determined while the table is positioned in a first table orientation. The table is re-oriented to a second table orientation, and a second orientation position of the object relative to the spindle is determined. A position of a table reference point along a first direction relative to the spindle is determined by averaging the first orientation position and the second orientation position, and a position of the spindle relative to the table is adjusted based on the position of a table reference point along the first direction.
