Abstract
A method and apparatus for defining a reference position of a tool with respect to at least one direction of movement is provided. The reference position is defined by comparing a position to which the tool has been commanded with the actual position of the tool with respect to the direction of movement. Lag data indicative of the difference is compared to a predetermined lag value, and advancement of the command position is terminated in response to lag data exceeding the predetermined data. The reference position is defined with respect to such lag data.
