Analysis of the contact mechanics in machining using a novel high-speed tribometer

A new high-speed pin-on-bar type tribometer has been developed to study the variation of friction coefficient with respect local thermomechanical contact conditions between tool and workpiece when drilling C45 steel. The forces temperatures are measured over a range pin indent depths sliding velocities in open closed loop tribo-systems. tribometer’s ability recreate is demonstrated induced surface modification by tribology testing studied.
