Deformations for foundations under static load are studied in present work, the effect of changing stiffening plates shape and cutting conditions such as type of cutting process and angle of cutting forces on these deformation are investigated using finite element program (ANSYS5.4) also effects of these parameters on the foundation natural frequencies are obtained. Keywords :machine tools, foundations, free vibration, static analyses, structure, finite element method. 1.Introduction: 3. The combined center of gravity of machine and foundation should as far as possible be To perform satisfactorily a machine tool must be in the same vertical line as the center of both s
