A STUDY ON THE PREDICTION OF ROUNDNESS VARIATION IN HONING USING HONEDYNAMICS

This paper describes the simulation for estimating roundness variation according to the process variables in the honing process based on hon e dynamics. Honing experiments were carried out to confirm the simulat ion results. The mandrel rotation speed and the workpiece stroke speed were treated as the main parameters in the simulation and the experim ent. The honing force, which varies dynamically in the contact between the honing tool and workpiece, is the main cause of roundness variati on. Honing tool and workpiece were assumed as a second-order system, i .e., a spring, mass and damper system in the modeling and analysis.
