Abstract
The bed has a significant impact on a machine tool's performance. The Bed of the Machine Tool has to be appropriately robust to absorb all vibrations and rigid enough to avoid deflections under different cutting forces transferred over the tool-post and carriage to the Lathe Bed. In general, the various permanent and moveable Lathe parts are supported by the Lathe bed. Typically, cast iron or mild steel are used to make lathe beds. When dealing with really large machinery, the bed may be constructed from two or more segments that are connected together to achieve the appropriate length. Large and robust, the lathe bed has a large ability to absorb machine vibrations during machining.This paper summaries, static structural and mode forms analysis are done on the lathe bed under maximum load circumstances. By incorporating ribs and reducing volume where loads and deflection are less caused, these simulated outcomes are utilized to lighten the lathe bed without sacrificing its structural integrity and dampening ability. As an alternative material, FEA analysis of a modified lathe bed is conducted using CAST IRON, MILD STEEL, and CFRP, this is a blend of epoxy resin hardener and granite. The efficiency of both materials is compared with regard to generated stresses, deformation, and weight reduction. CATIAV5 Modeling software was used to create lathe bed CAD Models. ANSYS 16.2 was used to generate the FE Model. ANSYS is used to perform the analysis. The observations are calculated and presented as contour plots to analyse the impact of reduced weight on the machine bed's structural strength prior to and after weight reduction, and decisions on the ideal design are made.
