Abstract
In industry the machine tool aims for high precision and repeatability while it is in operation. Generally machine tool contain several Structural components like base, saddle, headstock ,column of the machine tool play a vital role in helping to achieve consistent performance. Vertical machining center base selected for present study because base is the main structural part of the machine tool. It is a force bearing component of machine tool so it must contain high structural stiffness and good damping characteristics during machining operations. Otherwise it will affect accuracy and performance of that machine tool. So that to overcome this type of issue it is must need to analyze the structure. It is very difficult to analyse the structure analytically and the accurate results for stress, deflection etc. are the limitation of this method in Machine tool. So FEA is the best way to analyse the structural part of the machine tool. Static analysis is useful for estimating stresses, strains and deflections, whereas dynamic analysis deals with the prediction of natural frequencies and corresponding mode shapes, which will in turn, prevent the catastrophic failure of the machine tool .
