Abstract: A servo control system for a machine tool or the like requires only a single computational resource, such as a microprocessor, to provide coordinated control along multiple axes. No active control mechanism is required for any axis outside of the single resource. A real time multitasking approach enables the single resource to control multiple axes of motion, with the control of each individual axis being carried out by means of simple, yet effective, routines that conserve computing power. The routines also facilitate the generation of geometric designs in other media, such as the display of such shapes on a video screen or via a printer.

Abstract: A process for constructing machine tools. The process includes constructing a form, pouring concrete into the form, allowing the concrete to set, and grinding the sliding surfaces to be properly aligned and precision surfaces. Also disclosed are machine tools made by the process, and a method of assembling such machine tools.
