Machine tool construction calls for subassemblies with reduced weight while retaining excellent dynamic properties. Modern frame components do always meet required static stiffness but often display oscillation problems due to low component wall thickness. Breaking down solid steel structure into wide-area sandwich designes such as steel-aluminium foam-steel panels good static properties to be combinde with excellent properties since these sandwiches have 30 to 40 times the flexural strength due to their major geometrical moment of inertia in relation to adequate-mass steel sheet metals. In addition, the foam core dampens oscillations. Studies on foamed steel sections indicate that 2 to 3 times damping is likely in relation to unfoamed steel section. These benefits were the motivating for the relation to unfoamed steel section. These benefits were the motivating for the andwiches with dimensions of 1,500 mm x 1,000 mm. Dedicatingeforts to this new field of study has provided more favourable conditions for research of metal foams.
