Simulation of a cylindrical form grinding process by the
As shown in Fig 1, the grinding wheel is rotating about the z gaxis while translating along the helix of the work gear in a helical motionThe helical motion is usually divided into a rotation of the work gear about the z gaxis and a translation motion of the grinding wheel along the axial direction of the work gearThe coordinate systems, S u and S r, are rigidly connected to the form
