Finite element analysis and structure improvement of CNC grinding machine lathe bed

摘要

CNC grinding machine is the most commonly used finishing machine, lathe bed is the foundation of the machine tool key parts, as well as the guarantee for the machine tool dynamic stiffness. Taking a CNC grinding machine lathe bed as the research object, using Pro/E software to create the geometry model, and using finite element software ANSYS Workbench of simplified lathe bed for modal analysis. Through the modal analysis and find out the weak link of lathe bed and resonant frequency. In order to improve the dynamic characteristic of lathe bed, without changing job characteristics and difficult processing conditions, puts forward several improvement program, again on the proposed solution to the modal analysis. By contrast, determine the optimal structure of lathe bed improved scheme, for the structure design of lathe bed provides a theoretical basis.
