Novel non-traditional mechanical drilling process with squeeze motion

摘要: Abstract High-performance micro-drilling technology for printed circuit board materials is indispensable achieving further sophistication of electronic products. In this study, a novel mechanical drilling process, squeeze (SQUD) with non-rotating drill tool was developed. A an anisotropic stiffness characteristic designed based on the vibration mode. When excited in axial direction, it vibrates motion (combined translational and rotational directions) rather than rotating at ultra-high speed. Mechanical through intermittent cutting can be realized simply by applying vibration. addition to being able obtain high peripheral speed more easily speed, SQUD applied simultaneous machining multiple points. Experimental results indicate that process principle reliable holes. Additionally, ratio directions important characteristics success.
