Aiming　at　the　axle　material　30CrMoA　high　speed　cylindrical　grinding　force　calculation　problems,　a　consideration　of　plowing　force　grinding　force　model　is　established　based　on　the　Werner＇s　theory　model　of　grinding　force,　and　the　friction　force　and　plowing　force　coefficient　is　defined　as　variable　parameters.　On　the　basis　of　the　finite　element　analysis　software　DEFORM-3D,　a　high　speed　cylindrical　grinding　simulation　model　method　is　presented.Through　the　theoretical　value　and　simulation　value　contrast,　a　mutual　authentication　of　grinding　force　model　is　proposed.　According　to　the　simulation　analysis　results　of　grinding　force　and　grinding　wheel　speed,　grinding　depth　and　the　relationship　between　the　workpiece　speed,　theoretical　and　technical　guidance　for　the　grinding　force　calculation　and　the　selection　of　grinding　process　parameters　are　provided.
