Volume : II, Issue : VII, August - 2012 Design Optimization Of Cnc Verticalmilling Machine Bed B. Malleswara Swami, K.Sunil Ratna Kumar, CH.Ramakrishna DOI : 10.9780/22307850, Published By : Laxmi Book Publication 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. Keywords : Article : Cite This Article : B. Malleswara Swami, K.Sunil Ratna Kumar, CH.Ramakrishna, (2012). Design Optimization Of Cnc Verticalmilling Machine Bed.
