Dynamic Analysis of a CNC Machine Frame with a Focus on Different Definitions of Ball Linear Guides
Abstract
This article is written for the purpose of pointing out the problem that is focusing on creation of the FEM analysis by simplification detailed CAD model. Each simplification brings an error into the calculation. If designer do not fully understand to the design and specific simplification method, he can create the error that can lead to serious consequences. The created computational model shows the simplifications of the CAD model. To analyze response of the frame of the CNC milling machine based on different definition of roller linear guides, through MSC Marc for simulation and analysis, a simplified FEM computational model was created. Four variants of the replacement of the linear guides with the final evaluation of the results of each variant were described.
Keywords
