Beds, bases, columns and box type boxes are called "structures" in machine tools. In machine tools, 70-90% of the total weight of the machine is due to the weight of the structure. Researchers have worked with different types of materials such as cast iron, mild steel, granite and epoxy concrete for machine tool structure for different applications. Researchers suggest the profile of the machine tool and the selection of different reinforcements / ribs. The quality of the work produced on these machine tools depends directly on the quality and performance of the machine tools. To develop good products, design engineers need to study how their designs will behave in real-world conditions. The limitations of physical modeling techniques have led to the development of mathematical models representing a variety of mechanical structures. As in this approach, the entire structure is divided into finite elements, known as "finite element analysis". The FEA is a very useful tool in engineering today and has proven to be an important technique in the structural analysis of the machine tool. Thus, the Computer is an invaluable tool for a designer in his task of evaluating alternative designs to arrive at the optimum design and also to predict the static, dynamic and thermal behavior of the machine before reaching the final design.
The Young's modulus measures the strength of a material to elastic (recoverable) strain under load. A rigid material has a high Young's modulus and changes its shape only slightly under elastic charges (eg, diamond). A flexible material has a modulus of Young low and changes considerably its shape (for example rubbers). A rigid material requires high loads to deform it elastically - not to be confused with a strong material, which requires high loads to deform it permanently (or break it). The stiffness of a component means how much it deviates under a given load. This depends on the Young's modulus of the material, but also how it is loaded (tension, or flexing) and the shape and size of the component.
