Lapping machine with a cycloid tool trajectory

Аннотация

A lapping machine with a cycloid tool trajectory is proposed for precision plane finishing. The configuration of the machine is described, as well as the kinematics of the primary motion and the forces pressing the parts against the tool. Methods of controlling the density of the network of tool tracks are presented. To boost the productivity and final surface quality, a trajectory with high cutting speed—for example, a cycloid tool trajectory with a low density of tool tracks—is specified at the beginning of machining parts and then, as the margin is removed and the flatness of the machined surface is improved, the density of the network of machining tracks is increased to form the required microrelief.
