ABSTRACT
In this paper, a machine bed (Manufacturer: M/s Lokesh Machine Tools Ltd) is selected for the complete analysis for both
static and dynamic loads. Then investigation is carried out to reduce the weight of the machine bed without deteriorating its
structural rigidity and the accuracy of the machine tool by adding ribs at the suitable locations. In this work, the 3D CAD
model for the base line and the optimized design has been created by using commercial 3D modeling software CATIA. The
3D FE model has been generated using HYPERMESH. The analyses were carried out using ANSYS and Design
Optimization is done with the help of Optistruct. The results were shown with the help of graphs to analyze the effect of
weight reduction on the structural integrity of the machine bed before and after the weight reduction and conclusions were
drawn about the optimized design.
