Improvement On Cnc Drilling Quality Using Vibration Suppression Fixture

Since high precision and high efficiency are the essential competitive conditions, machining tables and the vibration caused by machining have been disturbing manufacturers with machining systems as the production spindle. This study focuses on solving or eliminating defective surface roughness caused by the vibration of CNC machining center during drilling. The CNC machining center combined with self-designed passive vibration table is applied to discuss the effect on the surface roughness in drilled holes. In the research process, NI LabView and NI OPC are proceeded the software/hardware protocol on the self-designed passive vibration table to apply vibration frequency to the vibration table. By matching the practical experience with the optimization experiment with Taguchi Method, 8 comparatively more important control factors related to machining and vibration are selected for parameter grouping and machining experiment through L-18(2(1)x3(7)) orthogonal table and calculating the S/N ratio and standard deviation.
