Measurement and Analysis of Threshold Forces in Diamond Roll Dressing

In this work, the forces and displacements in diamond roll plunge dressing are studied over a range of feed rates with the objective of investigating threshold forces. It describes the equipment, instrumentation, and data reduction methods used in the study. Building on previous work (King and Hahn 1986; Hahn and Lindsay 1970), this paper studies the normalized material removal rates and the normalized normal dressing forces as functions of time. Two regimes appear to exist as functions of feed rates. Each regime can be extrapolated to zero feed and makes a non-zero threshold with the force axis. The force threshold at feed rates above 3 mm/min. is 1.06 N/mm width of the grinding wheel, and the force threshold at feed rates below 3 mm/min, is 0.12 N/mm width of the grinding wheel.
