Abstract : The patent application concerns a process for wearing away precision mirror surfaces in such a manner as to precisely control the angles and depth of the resulting seats. Circular laps are used with rotary motion to prepare circular seats and segmented laps are used with oscillatory motion to prepare local seat segments. Vibration excitation using a piezoelectric crystal is provided for in a plane perpendicular to and in combination with the rotary and oscillatory motions. Also disclosed is apparatus for positioning the laps in parallel alignment with an optical plane within positional accuracies of + or - .1 arc seconds.
