Analysis of chatter in contour grinding of optical

2002-8-1 · Contour grinding is used to generate both spherical and aspherical surfaces. In contour grinding, a rotating grinding tool moves simultaneously in two orthogonal directions, X and Z, and the workpiece rotates about the Z axis, as shown in Fig. 2.The motion in the X direction is called cross feed. The motion in the Z direction controls the surface figure and depth of cut (d c).
