polishing process more effective, yet these technologies can cause trouble in CNC polishing machining. The elastic properties of the pad material change in the polishing time, but they do not have the main influence on the surface qual-ity [10]. It is more important to keep necessary accuracy be-tween the polisher and the workpiece [11].
