Research of Grinding Concave Paraboloiding Piece by Spherical Grinding Wheel
Aiming at the ultra-sophisticated combined working machine tool that was developed, the motion style of the machine tool when abrasive machining a sort of inward-curving-parabolic shape optical aspherical surface device is analysed, according to the equation of the machined part’s surface, the relative movement locus between the cutter and the machined part can be established while using a spherical grinding wheel as grinding cutter. The caliber of the paraboloid that to be processed is analysed, and the grinding wheel's installation angle is chosen, as well as the cutting speed of the cutting spot is analysed, the abrasive model in ideal condition is analysed, the basis is based for error compensating.
