<p>A method and apparatus for determining a force of a work tool as the work tool contacts a surface. The method and apparatus includes determining at least one non-contact force exerted on the work tool, determining a calibration factor as a function of the at least one non-contact force, determining a contact being made between the work tool and the surface, and determining the contact force of the work tool with the surface as a function of the contact being made and the calibration factor.</p> |
