Kinematic diagram - Wikipedia

A kinematic diagram or kinematic scheme illustrates the connectivity of links and joints of a mechanism or machine rather than the dimensions or shape of the parts. Often links are presented as geometric objects, such as lines, triangles or squares, that support schematic versions of the joints of the mechanism or machine. A kinematic diagram is sometimes called a joint map or a skeleton diagram.

Abstract. The substitution of many lapping processes by face grinding on lapping machines offers a new field of application for the kinematic model of relative motions in lapping. The selection of path types and velocities between parts and grinding wheels does not, as in lapping, primarily serve to avoid the profile wear of the wheels.
