Abstract

Methods and apparatus to determine a plunge depth position of material conditioning machines are disclosed. An example method incrementally adjusting a first plunge depth position of a first adjustable work roll and a first fixed work roll between an initial first roll plunge depth position and a final first roll plunge depth position. The method includes incrementally adjusting a second plunge depth position of a second adjustable work roll and a second fixed work roll between an initial second roll plunge depth position and a final second roll plunge depth position. The method includes measuring first pressure values of a first actuator associated with the first adjustable work roll at each incremental first plunge depth position, identifying a first relative minimum pressure value of the measured first pressure values, and determining a first incremental plunge depth position corresponding to the first relative minimum pressure value.
