Abstract: A modular surface element that can be arranged in a running bond pattern with other such modular surface elements. The modular surface element has a configuration comprising a decorative face, an opposed base, and sides extending therebetween generally orthogonal to the base. The sides are proximal to and within a modular perimeter defined by three non-alike pairs of opposed matching segments that are oriented substantially parallel to each other. At least two of the pairs of opposed matching segments are non-linear and at least two of the pairs of opposed matching segments are point symmetric. Optionally, the modular surface element may comprise two or more mating components.

Abstract: An EDM machine for machining a workpiece is disclosed. The EDM machine includes a machine frame having a central stationary machine body and a machining electrode to machine the workpiece. Machining occurs by producing a relative movement in at least one of an X axial direction and a Y axial direction between the machining electrode and the workpiece. The machine also includes a first axial slide for moving at least one of the workpiece and the machining electrode in the X axial direction, and a second axial slide for moving at least one of the machining electrode and the workpiece in the Y axial direction. The first axial slide is mounted in a substantially vertical plane on the machine body for lateral movement in a substantially horizontal direction.
