Horizontal Milling Machine Arbor Optimization by Parametric Iterative TechniqueDownload PDF
Milling arbor is may be considered as an extension of the machine spindle on which milling cutter are securely mounted and rotated. The arbor is subjected to complex stress conditions such as combine’s axial loads, bending and twisting moments and cyclic or dynamic loads . So it is necessary to analyze the behavior of the spindle under different loading conditions and with the use of different theories of failure. In this research paper milling arbor is analyzed using ANSYS software and the different stresses such as bending stress, torsional shear stress, principal stress and von-misses stress are determined . The results are validated against analytical solution and the errors are within the allowable limits, and shape optimization using iterative technique is done based on the stress valve obtained; an iterative process was carried out. A new Shape was formulated whose stress valve well within the limits.
