Precision grinding is the process of removing metal from a workpiece to achieve a specific size, shape, or surface finish. Surface grinding is a type of precision grinding that is used to create flat surfaces on metal workpieces. This process involves using a grinding wheel to remove tiny bits of material from the surface of the workpiece until it is smooth …

However, if the concave surface of the part is deep, the grinding wheel shank will interfere with the workpiece when the grinding wheel is placed perpendicular to the work. Therefore, the cross axis grinding method is mainly applied to the manufacturing of asphere with convex form or with comparatively large aperture [10].
