Computer software for digitizing sensor signals from sensors, attached to mechanical objects or structures, that produce an electrical representation of mechanical forces, acoustical sounds, and /or electrical power, then analyzing the digitized data extracted from such sensors for variations in electrical characteristics, then producing a quantitative measure and/or representation of the physical condition of a mechanical object; e.g. fatiguing of metal, deterioration and/or decreased repeatability of a metal machining process, mechanical stresses in a rigid body, dullness of the tooling used in the machine of solid materials
