Development of Parrametric Modeling for the Spindle of NC Milling Machine Based on ANSYS

Abstract

With the development of manufacturing technology, modern CNC machine tools are greatly improved in machine processing range, dynamic performance, the processing precision and reliability with the help of the modern design technology, process intensification and the new function part. The research object is mainly based on a CNC milling machine spindle system, using ANSYS software for the spindle of machine tool modeling, and then puting the design parameters into the already built parameterized model. It is known that the spindle is in high speed operation of the deformation and vibration characteristics by analyzing, the some unreasonable parameters were improved using some assumptions, so that the spindle is more stable and reliable in high speed and super high speed running dynamic performance, thus improving the processing precision fastly. Through the model analysis, this step is simplified in manufacturing prototype, thereby simplifying the cost, shorten the design cycle.
