Abstract

To perform satisfactorily a machine tool must be both statically and dynamically rigid. Its static stiffness determines its ability to produce dimensionally accurate parts and its dynamic stiffness affects both the quality of the component's surface finish and the maximum metal removal rates that can be achieved. Virtually all medium to large machine tools rely upon a concrete foundation to provide adequate structural support in-order that the machine is sufficiently rigid to perform satisfactorily. This paper describes the theoretical analysis and subsequent validation of an investigation into the static stiffness of the concrete foundation for a large moving gantry machining centre. The analysis was carried out using the latest Finite Element Analysis (FEA) software [1] and the results were physically validated by measurement of the foundation deflections under a variety of applied loading conditions.
