Abstract: In Industrial world CNC machines are dominating because of its versatile form of automation. The structural materials used in a machine tool plays a decisive role in productivity, accuracy and surface finish of the parts manufactured in it. The materials which have high stiffness and good damping characteristics are only used as structural materials in machine tool to withstand high operating speeds. The vibrations developed in machining operation gets transferred into machine tool structure. The conventional structural materials such as cast iron and steel develops positional errors due to vibrations transferred into the structure at high operating speeds. We know that by experiences, the proportionality of the life of a machine is inverse to the levels of vibrations that the machine is subjected. In this work, a machine bed is selected for the analysis on static loads. Then work is carried out to overcome the limitations in structural material, conventional materials are replaced with composite materials having high stiffness and good damping characteristics. The main aim of this work is increasing and reducing the structural weight. A 3D CAD model of the machine bed is created by using SOLID WORKS and analysis were carried out on different composite machine bed using ANSYS workbench.
